viva thesis meaning

Viva examinations: guidance

This guidance explains the viva process, how to prepare, what will happen on the day and what the possible outcomes are.

This information is for postgraduate research students. It covers:

• before your viva
• preparing for your viva
• during your viva
• outcomes of the examination

Before your viva

Entry forms.

You must enter the exam via Portico about four months before you are ready to submit. You may not submit your thesis until you have entered for the examination and your examination may be delayed if you have not done this.  

Find out more about examination entry

Your supervisor is responsible for arranging the appointment of your examiners. This should be done at the same time as you complete your examination entry form, four months before you are due to submit your thesis. Examiners are appointed by UCL for their professional services as examiners with expert subject knowledge. A minimum of two examiners, one from outside UCL and (normally) one from UCL are appointed to co-examine all research degree candidates. The examiner nomination form can be found here .

Submit your thesis

Find out more about formatting, binding and submitting your thesis.

Collaborative research projects

If you are contributing to a collaborative research project you must include this information in the introduction to the thesis. You must clearly identify the demarcation between the research you are submitting for examination as an original contribution to knowledge and the work of your collaborators. 

Viva arrangements

Your supervisor (or nominee) will liaise with you and your examiners to arrange and confirm a mutually convenient time and place to hold the viva examination. The viva must not be arranged before the examiners are formally appointed by UCL. It may take place at UCL, or remotely. Your examiners should have your thesis at least six working weeks before the viva and you will receive an email once the thesis has been sent to the examiners. At this point, you will be able to record the viva via the ‘Research Student Administration’ section in Portico. A user guide is available with step-by-step instructions for submitting this information. Your viva should then take place within three months of the dispatch of the thesis to your examiners.

Reasonable adjustments

If you or one of your examiners have a disability which UCL cannot accommodate, other reasonable arrangements can be made for the viva. You must make a request in writing when you complete the examination entry form to allow time for arrangements to be made. 

Preparing for your viva

We recommend that you re-read your thesis. Try to anticipate questions, comments and criticisms, and think how you would respond. Although you may not be able to anticipate actual questions to be asked by the examiners, this approach will encourage you to think actively about your work.   You should also refresh your memory of the relevant literature. Do not attempt to re-read every paper in the bibliography of your thesis; instead, re-read carefully some of the more recent key references. If you have left university after submitting your thesis you may be unaware of very recent work. Ask your supervisor a couple of weeks before the viva whether any work of direct relevance to your thesis has been published since you submitted your thesis.

You must not contact your examiners directly at any point leading up to the viva or afterwards.  All contact should be done by your supervisor or other relevant departmental staff member.  

A good way to prepare for your viva is to practice. Your supervisor should give you a mock viva, or arrange for this to be undertaken by a member of your upgrade panel.  

During your viva

A viva is an academic interview at which your examiners will be looking for an understanding of the subject matter of your thesis, an appreciation of its significance to established knowledge in the field, and an awareness of the breadth of the subject area. 

Your supervisor will be invited to attend your viva examination, unless you request otherwise; you must indicate this on your examination entry form. Your supervisor does not have the right to participate in the viva examination but may contribute if invited to do so by the examiners.  

The examiners will expect you to:

• show a critical analysis of your own work and of that of others
• appreciate the limitations of the methods employed and the results obtained by yourself and others
• understand how the broad conclusions of your thesis support, add to or conflict with previous work
• know the major concepts and recent developments in your subject

There is no formal procedure laid down for the conduct of the viva examination. Some examiners prefer to work through the thesis in the order in which it is written. Other examiners prefer to discuss topics. Very few examiners will perform a page by page criticism. You may be asked to prepare a presentation of your work in a suitable format.  

You are not expected to know your thesis by heart, but to refer to the appropriate page when the examiners wish to discuss a specific point. Please ensure that you bring to the viva examination a copy of your thesis paginated in the same way as the copies you have submitted to the Research Degree Examinations Office.

You should not simply answer 'yes' or 'no' to questions nor give a prepared exposition. Try to answer the question as it is put, remembering that you are engaged in an academic conversation.

Be prepared to justify your ideas and conclusions. If the examiners challenge your interpretation but you feel that your case is a good one, muster your arguments and be willing to present your case firmly but courteously. However, if the examiners have identified a genuine weakness, concede the point gracefully. Even if you feel the examiners are unreasonably critical do not become argumentative or allow the discussion to become heated. You can agree to differ and to reconsider the point. All participants in the viva must abide by UCL's Bullying and Harassment Policy . If you make any comments to your examiners which put them under moral pressure, for example alluding to what will happen if they fail you, or if you offer any incentive to your examiners to pass you, they must terminate the examination and report to the Chair of the Research Degrees Committee via Research Degrees in Student and Registry Services.

Outcome of the examination

The following are the three most often received results and the subsequent procedures.

We will email you with reports from your examiners, copied to your supervisor, instructing you to submit the following documents:

• the electronic copy of your thesis 
• thesis deposit agreement form (uploaded with the e-thesis)

We will award your degree once you have met the academic conditions, the Library have confirmed receipt of your e-thesis and the Deposit Agreement form, and you have cleared any outstanding fees. 

The electronic copy of your thesis and thesis deposit agreement form should be deposited to the Library via UCL's Research Publications Service. Please make sure that you remove, or blank out, all personal identifiers such as signatures, addresses and telephone numbers from the e-thesis. Any photographs that you have taken should not show identifiable individuals without their permission and any you have taken of children should mask their faces. If you have any queries regarding this aspect of the process, please contact the Library directly.

UCL no longer requires a printed copy of your final thesis. If you do wish to deposit a hard copy you can do so by sending it directly to the Cataloguing & Metadata department of Library Services by post, or in person at the Main Library help desk.  You will find more information about the process on the existing webpage for e-thesis submission. 

Find out more about depositing an electronic and printed copy of your thesis

Once you have submitted these, we will send an email containing the confirmation of award and your reports to your email address you have recorded on Portico. The degree certificate will follow approximately four months after the official award date.

In the case of an examination for specialist doctorates (including the EngD, EdD and MPhilStud), the award of the degree is also conditional upon students passing all taught elements of their programme of study. The modules should be entered on to Portico by the Department and confirmation these elements have been completed will be passed from the Examinations Department to Research Degrees.

Minor corrections

This is by far the most common result received from the examiners. 

We will email you with reports from your examiners, copied to your supervisor and Faculty Graduate Tutor. The deadline to submit your corrections officially starts from the date of this email, which will also indicate the name of the person designated to check your corrections. This deadline is for you to submit the corrections to the designated checker, and not to submit the final copy of your thesis.

Your examiners may have returned an annotated copy of your thesis to you and therefore you may already be aware of the work required. The designated checker should inform you of the format he/she expects to receive the corrections, although normally this will be in electronic format.

The designated checker should confirm the outcome of the examination within one month of receipt of the minor corrections to the thesis. This is usually done by sending an email directly to Research Degrees.

Once this has been received we will follow the procedure for a pass result.

Resubmission in a revised form

We will email you with reports from your examiners, copied to your supervisor, Departmental Graduate Tutor and Faculty Graduate Tutor. The 12 or 18 month deadline officially starts from the date of this email.

Unlike the outcome for minor corrections, where one person checks the amendments, the resubmission requires you to re-enter for the examination and submit two copies of your thesis for forwarding to the examiners. 

Your examiners may have returned an annotated copy of your thesis to you and therefore you may already be aware of the work required. 

Once you have completed the corrections, you will need to:

• submit a new exam entry form to Research Degrees at least two weeks prior to the expected submission of the thesis
• submit an electronic copy of your thesis to Research Degrees via the UCL Dropbox.  

Find out more about formatting, binding and submitting your thesis. Your supervisor will be emailed to confirm that the examiners are still willing to act and provide their current contact details. This is to avoid the thesis from being sent out incorrectly. We will then send an email to your supervisor and examiners reconfirming their appointment and send the thesis to them via the UCL Dropbox.

If the examiners have requested a second viva, your supervisor will arrange this. In these circumstances, the procedure will follow that of a typical research degree examination.

If a further viva is not required, your examiners are only required to submit a joint report. They cannot award another 18 month resubmission, but can allow minor corrections.

Once the reports are received we will follow the procedure for either the pass or minor corrections result.

Other results

If the result falls outside the above descriptions, we will email you detailing the procedure you will need to follow.

Defending your doctoral thesis: the PhD viva

Format for defending a doctoral thesis.

Every institution will have specific regulations for the thesis defence. In some countries or institutions, the convention is for thesis defences to be public events where you will give a lecture explaining your research, followed by a discussion with a panel of examiners (opponents). Both your examiners and the audience are able to ask questions.

In other countries, including the UK, the oral examination is usually conducted behind closed doors by at least two examiners, usually with at least one being from another institution (external examiner) and an expert in your topic of research. In the UK the supervisor does not participate in the viva, but may be allowed to observe. Sometimes someone from your own institution is appointed as an independent chair. Although it is now becoming more common for the candidate to have an opportunity to give a public lecture in UK institutions, this does not form part of the examination and may or may not be attended by the examiners.

Viva preparation

Take the preparation for your viva seriously and devote a substantial amount of time to it. The viva preparation checklist may be useful to help you prepare.

Your institution may offer courses on viva preparation and there may be opportunities to organise a practice viva. Take advantage of these opportunities: they can be extremely valuable experiences.

Things you may wish to take with you

• your thesis – mildly annotated if you wish
• a list of questions that you might be asked and your planned responses
• any questions that you want to ask your examiners
• additional notes which you have made during your revision
• list of minor corrections that you have come across during your revision.

During the viva

Your study will have strengths and weaknesses: it is essential that you are prepared to discuss both. You could think of any weaknesses as an opportunity to demonstrate your skill at critical appraisal. Examiners will seek to find and discuss weaknesses in all theses. Do not interpret criticism as indication of a possible negative outcome.

Examiners have different personalities, styles and levels of experience. Sometimes a candidate may feel that a challenge is made in a confrontational way. Experienced, effective examiners will not be inappropriately confrontational, but some will. Do not take offence. A relaxed, thoughtful, and non-confrontational response from you will help re-balance the discussion. Having an independent chair can help maintain a constructive environment.

Useful tips for during your viva:

• Ask for clarification of ambiguous questions or ask for the question to be repeated if necessary
• Take time to think before answering
• Be prepared to ask questions and enter into a dialogue with your examiners
• Be prepared to discuss your research in context of other work done in your field
• Be ready to admit if you don't know the answer to a question
• Be prepared to express opinions of your own

You are not expected to have perfect recall of your thesis and everything that you have read and done. If you get flustered, or need to refer to notes your examiners will understand. They have been in your situation themselves!

After your viva

There are several possible outcomes   of a thesis defence. Most commonly, your examiners will recommend to your institution that you are awarded your degree subject to minor corrections, although in some instances they might ask for more substantial work.

How the viva process works

The viva is a long-established part of the examination process for a research degree. The main focus of the assessment is on the written thesis/dissertation (and other outputs, for a Practice as Research students). However, the viva, which is the oral part of the assessment, is used to inform the examiners’ final assessment decision.

The viva gives the examiners the opportunity to explore any issues in detail and provide inspiring advice for your future research career. Examiners may have a strong sense of the outcome from reading the thesis, but the viva gives you an opportunity to defend your work, as well as to validate the thesis and demonstrate your skills in participating in academic discussion with research colleagues.

Viva arrangements

Your department is responsible for nominating two examiners: one internal and one external, whose names must be approved by the Faculty Dean (Postgraduate).

The internal examiner is expected to undertake any arrangements necessary for conducting the viva. You’ll then be contacted to confirm the arrangements for the examination of the thesis, including the date and time of the viva.

The viva should be held no later than two months after your examiners receive your thesis for examination unless exceptional circumstances prevent it from happening. In the case of a staff candidate, the department must nominate two external examiners, rather than an internal and an external, and an Independent Chair is appointed to oversee the examination process.

Students who fail to engage in viva arrangements, to the extent where it has not been possible to conduct a viva, shall be deemed to have withdrawn permanently from the University.

Viva format

Two formats are available as standard viva examination formats of the University: Video Link Vivas and In-Person Vivas. The availability of both video link vivas and in-person vivas means that the most appropriate format can be sought, to support any individual needs and adjustments appropriately, including cultural and/or interpersonal challenges.

Video Link Vivas provide the ability to expand the network of external examiners internationally as potential barriers, such as financial constraints, time commitments and our environmental efforts to reduce our carbon footprint, are removed. There are both financial and time-saving benefits for all viva attendees, including candidates, who will not have to bear the costs of returning to campus for their viva.

The diverse nature of some thesis and viva formats (including, but not limited to, Practice as Research examinations) are potentially not well-suited to the video link format, so this should be considered when deciding on the viva format.

In advance of the thesis submission, students should discuss with their supervisor which examination format is most appropriate and preferred. Where possible, the department will look to accommodate a student’s preference, and will liaise with the examination team before making a decision.

Venue (in-person vivas)

In cases where the viva is taking place in-person, the venue for the viva should normally be on campus, reasonably quiet and allow the viva to proceed without interruption.

The Faculty Dean (Postgraduate)’s approval is required for a viva to be held at a venue outside the University of Essex or one of its Partner Institutions.

Technical preparation (video-link vivas)

The University recommends the use of Zoom as its preferred and supported video- conferencing software. The Graduate Administrator within each Department/School will be responsible for arranging the Zoom meeting, and wherever possible a University video- conferencing room should be used.

Technical assistance will be provided by Audio Visual Services as required. This will include practical advice on the protocols of communication by video link. Time should be allowed before the start of the viva to ensure the software and equipment is working correctly, and that all parties are satisfied with the arrangement.

Who attends?

The viva will normally only involve the internal examiner, the external examiner and the student.

The Faculty Dean (Postgraduate) may appoint an Independent Chair, who is a senior member of the Academic or Research staff of the University of Essex, to oversee the conduct of the oral examination in line with the Policy for the Appointment of Independent Chairs for Research Degree Vivas  (.pdf).

The student’s supervisor can only be present in exceptional circumstances, approved on an individual basis by the Faculty Dean (Postgraduate) and with the agreement of the external examiner.

The length of a viva will vary but if it is longer than two hours the internal examiner will recommend an adjournment for a break.

If you feel the need for a break earlier than two hours, please feel free to inform the examiners. Any breaks taken will not affect the outcome of the viva.

Discussion between examiners

Once you’ve submitted your thesis and the examiners have been appointed, copies of the thesis/dissertation and examination paperwork are sent to the examiners by the Postgraduate Research Education Team.

The examiners must not contact each other to discuss their assessment of your thesis, nor engage in discussion with you ahead of the viva, except for when making logistical arrangements. On the day of the viva and before seeing the student, the examiners will have a pre-viva meeting at which they discuss their initial assessment and agree the approach to the viva, including the areas of questioning.

It is the responsibility of the internal examiner to oversee the proceedings at the viva and to ensure that the University’s Principal Regulations for Research Degrees are adhered to, unless an Independent Chair has been appointed.

The start of the viva

At the start of the viva, the internal examiner will introduce the examination team, confirm the purpose of the viva, and explain how the viva will proceed. If there is anything you’re unsure of, now is a good time to ask.

Questioning

Remember, no one is perfect. There will be strengths and weaknesses to your research and your examiners will want to explore these in more detail.

Normally, the examiners will start with some general/introductory questions that will ease you into discussing your thesis and research. These will be followed by a discussion of strengths and weaknesses of the thesis. It will be an opportunity for you to demonstrate your abilities of self-analysis and reflection, exploring things you’d do differently in future and what you’ve learnt during the process.

The examiners will be asking questions to provide clarification, and seek explanation and elaboration where appropriate. Please remember that each examiner has a different style, and some questions may appear quite direct and challenging. In this situation, it’s important to stay relaxed and take your time to give a thoughtful response.

If you are asked a question which you don’t understand, feel free to ask for clarification.

Reaching a decision

Once the viva has finished, you’ll be asked to leave the room, whilst the examiners reach a conclusion about the recommended result. The result will be one which is listed in the University’s Principal Regulations for Research Degrees .

You’ll then be invited back into the room to be told the recommended result and the reasons for the decision. If corrections are required, you’ll be sent a written list of corrections after the viva.

What is a viva? PhD viva, viva voce, viva process and more

If you are a PhD candidate and preparing to take the biggest step in your academic journey, you might be overwhelmed by the thought of your impending viva voce or the oral defense of your thesis.

Worry not, we are here to demystify the process and provide you with actionable tips to successfully navigate this crucial academic milestone.

Here, we will guide you through the viva process, shed light on the perspective of your examiners, and help you understand how to prepare for this pivotal examination. 

Whether you’re just beginning to wrap your head around what a viva entails or are already deep in the trenches of preparation, this blog is designed to offer you comprehensive, step-by-step guidance.

By understanding the process, expectations, and preparing effectively, you can walk into your viva with confidence, ready to defend your thesis and demonstrate your deep understanding of your research area.

What is a PhD viva or viva voce?

A PhD viva or viva voce is an oral examination where you defend your thesis in front of internal examiner(s) from your institution and/or external examiner(s) from another institution specializing in your subject area.

There may be up to 5 people on your viva panel. 

They are testing your knowledge and thought processed to be admitted into the degree.

Typically lasting for an hour and a half to two hours, the viva is a conversation between experts, giving you the chance to elaborate and clarify your research.

Preparation for the viva can involve ongoing conversations, with supervisors and focused development after thesis submission.

As the viva voce derives from the Latin for ‘living voice,’ let your passion for your research come alive in your defense.

As nerve-wracking as it might be, remember to relax and use this opportunity to share your contribution to your field. 

Supervisors will (or at least should) conduct mock vivas to help you prepare for questions and build confidence. Ask for a mock viva if one is not offered by your supervisor. 

During the viva, your supervisor may be present as a silent observer, ensuring examination conduct.

Outcomes of a viva range from:

• passing without corrections,
• passing with minor or major corrections,
• or not passing at all.

Examiners won’t necessarily spot all mistakes, but they read your work thoroughly, engage in a comprehensive discussion, and submit independent reports before the viva.

Understand what’s expected of you in your viva (Examiner point of view)

From an examiner’s point of view, in your viva, you are expected to confidently explain and defend your thesis.

You should be well-prepared, recognizing that examiners will carefully read your work and may identify minor mistakes.

Keep in mind that examiners may not know your thesis as well as you, so be prepared to clarify and elaborate on your research. 

They may ask some really simple and basic questions of you – particularly early on in your thesis defense.

It is essential to demonstrate your understanding of the topic and address any questions posed by the examiners.

You may have the option to include your supervisor or other supportive figures from your institution during the viva for moral support and to witness the examination’s conduct.

Understand that examiners typically work independently and exchange reports just before the viva, so be ready to engage in a comprehensive discussion about your work.

Focus on showcasing your:

• research abilities, and
• significance of your thesis

during the viva.

How to prepare for your viva exam

To prepare for a PhD viva, follow these actionable steps:

1. Familiarize yourself with your examiner’s and supervisor’s work (4-5 days): Know their research interests, potential biases, and recent publications, and consider how they might relate to your thesis.

2. Understand your thesis deeply (5-6 days): Be able to explain your research question/hypothesis, aims, theoretical framework, methods, and key results concisely. Review all the papers you discussed or mentioned in your thesis, noting their relevance to your work. Address any weaknesses in your analysis, and justify your study’s merit to earn a PhD.

3. Practice summarizing your thesis: Prepare a 200-word summary of each chapter and a 2-minute explanation of your whole thesis. Be ready to clarify your work in one or two sentences.

4. Anticipate general questions : Examples include summarizing your thesis, stating your research question or hypothesis, and discussing your main results. Prepare answers for potential questions from both a general and discipline-specific context.

5. Conduct mock vivas with your supervisor: Simulate the viva experience to get comfortable with the format, build confidence, and receive feedback on your performance.

6. Review general questions and answers (last 1-2 days): Brush up on your prepared responses and make any necessary final adjustments.

Remember, most PhD students pass their viva, so focus on preparing and confidently discussing your research.

Things to keep in mind during your viva – top tips

Here are the top tips to keep in mind during your viva:

1. Ask for clarifications if a question is unclear. Be polite and ensure you understand the question before attempting to answer it.   2. Don’t interrupt the examiner while they are asking a question. Give them time to finish, as it shows respect and allows you to fully comprehend the inquiry.

3. Be honest if you don’t know the answer to a question. Prepare a polite response for unexpected questions you cannot answer.

4. Maintain confidence without arrogance. Display a level of nervousness that reflects your dedication to the process, but avoid overconfidence or disrespect.

5. Keep your answers concise and structured. Use a clear format when providing your response, such as breaking it down into key points.

6. Speak at a moderate pace. Avoid talking too fast or too slow, as it can be distracting for the listeners. Practice controlling your speech rate during your preparations.

7. Give yourself plenty of time before the defense to prepare and relax. You should be in the right state of mind for your viva.

8. Be familiar with the protocols, format, and panel of your viva. Attend other thesis defenses, read your institution’s guidelines, and research the background of the examiners on your panel.

By following these tips, you can enter your viva well-prepared and have a successful defense. Enjoy the experience and demonstrate the hard work you have put into your research.

Wrapping up – thesis viva

Concluding our comprehensive guide on the viva process for PhD students, the final thought we leave you with is this: your PhD viva, or viva voce, is an opportunity to defend your research, a unique chance to demonstrate your motivation, strengths, and even your limitations as a researcher.

It’s important to understand the viva definition in its entirety: a viva voce is an oral test undertaken in front of a panel of examiners.

This panel usually includes one internal examiner from your institution and one external examiner from another. It may also include other experts depending on policies and practices.

Preparation is key when you get to the viva stage.

To that end, arranging a mock viva with your supervisor could help you anticipate the types of questions you’ll be asked. This practice could enable you to put your best foot forward during the real deal.

Don’t be surprised if the viva examination lasts anywhere between one and four hours.

You may be asked to elaborate on your PhD thesis, defend your field of study’s claims, discuss its strengths and weaknesses, and suggest future research opportunities. Your response to the assessment task should be in-depth and thoughtful.

Under the current COVID-19 conditions, many students are having their viva over Zoom or Skype.

In these cases, it’s important to arrange your setting to minimise distractions. Feel free to ask for clarification if the audio cuts out or you miss a question.

In preparation for your viva, review the academic profiles of your panel members, anticipate questions they might ask, and keep a copy of your thesis at hand.

Also, remember that while it’s important to provide an in-depth response, a concise explanation is ideal to avoid going on a tangent. If you’re asked about any weaknesses or limitations in your work, be honest and thoughtful in your response, highlighting your problem-solving skills as a researcher.

You’ve worked hard to reach this stage; now it’s your chance to shine! Best of luck!

The Oral Examination (viva) - Doctoral degrees, MSc and MLitt

If you have not been advised of the date for your viva within six weeks of submitting your thesis, you should contact your Degree Committee.

Location of the viva

The viva will normally take place in-person in Cambridge, but you may choose to be examined remotely by video conference. You should inform your Degree Committee of your preference when you notify them of your intention to submit/apply for appointment of examiners. Please also make your supervisor aware of your preference as it may affect the choice of available examiners.

Arrangements where you and one examiner are co-located in Cambridge, with the second examiner participating by video conference, where both examiners are co-located and you participate by video conference, or where you and the examiners are all in separate locations, are permissible provided all parties agree.

In-person oral examination:  In-person examinations may be delayed depending on the availability of the examiners as travel time will need to be factored in. Students who are overseas and returning to Cambridge for their viva should contact the International Student Office for visa advice if their student visa has expired or will be expiring soon.

Video conference oral examination: A guide to conducting vivas by video conference can be found here .

The choice of in-person or video conference viva does not constitute procedural irregularity grounds for complaint should you fail the examination.

Adjustments to the oral examination on the grounds of disability

If you wish to notify examiners of a disability or request adjustments on account of a disability for your viva (either your first year assessment or final examination), you can do this via your Degree Committee by completing and submitting the voluntary disclosure form . It is recommended you do this at least four weeks before your expected date of examination to allow time for appropriate recommendations and adjustments to be made. 

Once you have submitted the form, your Degree Committee will contact the University’s Accessibility and Disability Resource Centre (ADRC) who will advise the Degree Committee on the appropriate course of action. You may be contacted by the ADRC if additional information is required or to provide you with an offer of additional support.

The information provided on the voluntary disclosure form will be kept confidential and will not be used for any other purpose.

If you already have a Student Support Document (SSD) that includes recommendations for adjustments to the viva , and you have given permission for the SSD to be shared with the Degree Committee, you do not have to complete the voluntary disclosure form but may do so if you wish.

What happens at the viva?

• The viva will normally take place in Cambridge, although some may take place via video-conference (please see above)
• It is carried out between yourself and the two examiners and is conducted in English
• It may include an Independent Chairperson if the Degree Committee requires this
• There is no set duration, but a viva will normally last between 90 minutes and three hours
• You may be required to do a presentation - please check with your Department whether this is the case. If you are required to give a presentation, you should be informed at least two weeks in advance of the viva
• The viva cannot be recorded
• Your supervisor cannot attend the viva

Your Department should advise on any department-specific conventions or procedures.

Purpose of the viva

The viva gives the opportunity for:

• you to defend your thesis and clarify any matters raised by your examiners
• the examiners to probe your knowledge in the field
• the examiners to assure themselves that the work presented is your own and to clarify matters of any collaboration
• the examiners to come to a definite conclusion about the outcome of the examination

Possible outcomes of the viva

The possible outcomes are:

• Conditional approval - pass without correction (but for doctoral degrees subject to submission of hardbound and electronic copies of the thesis ); or pass, subject to minor or major corrections 
• Revision and resubmission of the work for a fresh examination
• Revision and resubmission of the work for a fresh examination or acceptance of the MSc/MLitt without further examination (but possibly subject to corrections)
• Not to be allowed to revise the thesis, but offered the MSc/MLitt without further revision or examination (but possibly subject to corrections)
• Outright failure

Notification of the result of the viva

Your examiners are asked not to give any direct indication of the likely outcome of the examination as the official result can be confirmed only by Student Registry on behalf of the Postgraduate Committee. Following your Degree Committee's meeting they will forward their decision to the Student Registry who will email your reports to you, copying in your Supervisor.

Process following the viva

5 tips for passing your PhD viva

Every Doctoral researcher is expected to defend their thesis through an oral test - so discover how to prepare for your PhD viva and ensure you make a good impression on the examiners

What is a PhD viva?

A viva voce is an oral test, which literally translated means 'with the living voice'. It's a focused discussion giving you the opportunity to present your PhD thesis and then defend it in front of a panel of academic experts.

1. Understand what's expected of you

Traditionally, your thesis would always be discussed in person, with the interview style viva exam overseen by at least two (internal and external) examiners. Afterwards, they would provide you with a joint written report detailing any corrections that need to be made.

However, following the coronavirus (COVID-19) pandemic, the online PhD viva has become more commonplace with this examination more likely to take place via Microsoft Teams, Skype or Zoom.

The virtual experience will still typically follow the same format, but you'll be briefed in advance about the arrangements and any technical aspects to bear in mind. You can prepare for an online PhD viva by reading our video interview tips .

The chair of the viva is usually the internal examiner, although it can be an independent person. If you and the examiners agree, your PhD supervisor can also be present.

The examiners' main objective is to ascertain that you've written your own thesis, so if you have and are ready to talk through how you completed it, there's no need to panic. You may even enjoy the viva voce test.

In addition to assessing your thesis, the examiners are also there to assist you in deciding how and where this research might be published.

There are various results between a 'pass' and 'fail' but it's very rare to slip up at this point of a PhD. Most Doctorate awards will be made upon the condition that a number of minor corrections are made, with re-submission requests far less common.

However, while the pass rate is high, the viva exam itself can still be intellectually demanding. This is because you'll be debating issues that are conceptually complex, so preparation is crucial to your success.

At the end of it, whatever the outcome, be prepared to take on board any advice, as the examiners are there to help you improve your argument or the presentation of your thesis.

2. Know your thesis inside out

While you can be sure this isn't a memory test - as you're fine bringing notes and a copy of your thesis with you to the PhD viva - it's still important to gain a good understanding of what you've written and be knowledge about your field of study.

You'll need to think carefully about where this original piece of work would be placed in the context of the wider body of research carried out in this field. Questions will surely be asked about this, as well as whether the project could possibly be developed further through any future research.

As you'll be explaining parts of the document to the examiners (who'll also have a digital or physical copy), make sure the pagination is the same in your version as the one they're looking at to avoid any issues regarding everybody being on the same page.

If you get stuck at any point during the viva exam, you can use looking at the thesis as an excuse to re-focus and gather your thoughts.

3. Anticipate the viva questions

The examiners will have prepared a series of questions for you to answer at the viva voce, but this is nothing to get too concerned about. The questions will all be based on your thesis - what it's about, what you did and what you found out - and why this matters, in relation to your field of study.

So when getting ready for the viva, consider the types of questions you're likely to be asked, including:

• What original contribution has your thesis made to this field of study?
• Explain the main research questions you were hoping to address.
• What are the strengths and weaknesses of your thesis?
• If you had to start the thesis again, what would you do differently?
• If funding was no object, describe how you'd follow on from this project.
• What are your plans for the future?

It can be helpful to practise your answers beforehand, ideally vocalising them by arranging a mock mini viva - although, as you aren't restricted in terms of referring to notes in the exam, you can leave room for spontaneity, and you don't need to learn it all off by heart. If your viva is being held online, you can ensure any technical issues are identified before the day by having a run through with your supervisor or a friend.

While it may sound simple, stick to answering the questions posed. It's really easy to go off on a tangent and this can open up other lines of enquiry from the examiners - possibly in areas you hadn't expected to be quizzed about.

On the other hand, it's completely fine to bring personality to your reasoning and use stories as a means of describing the learning process you've gone through and the techniques mastered over the last three or four years that have brought you to this point.

4. Learn about your examiners' own work

The senior and well-respected academics who'll be reading your thesis will have their own ideas on conducting PhD standard research. Therefore, it's worth taking a look online at their academic profiles to discover if there's any correlation with the research they've had published and your own work.

From this, you should be able to gain a better idea of their motivations, their possible views on your thesis and the kinds of questions they might wish to discuss after having read through it.

You should research up-to-date theories, read any recent papers on the subject and speak to others who've recently had their own viva exam. Think about how your work differentiates from the research carried out by others in your chosen field.

Prepare to provide any supporting evidence asked of you by the examiners - for example, they may request to see experimental data you mention once the exam is over.

It's also necessary to check the policies and practices in place at your university and be sure of what the roles of the examiners are and how the viva panel will be structured. In many cases, Doctoral students can choose the examiners conducting the PhD viva.

5. Plan towards the viva exam

From the moment you know the date of your viva voce, work backwards and plan the steps you'll need to take before the day itself. Allow enough time to assess and review your work so that as the day approaches, you can focus on the practicalities.

This encompasses everything from making sure you relax, eat and sleep well the day before to arranging transport so you get to the viva on time - if you're attending in person.

An online PhD viva will present its own challenges, so ensure your working space is presentable and you still make an effort in terms of what you'll be wearing.

It's always advisable to adhere to interview etiquette and go with something that's both smart and comfortable. By looking the part, this should get you in the right frame of mind to communicate in a professional manner.

In the build-up, avoid any situations that might make you feel stressed and instead try to adopt a positive attitude, one that results in a genuine eagerness to engage in a debate about the work you've been toiling over for a substantial period of time.

If you're travelling to the examination, be sure to check that you have everything you wish to take with you, including the thesis, plus any notes or other materials that will help support your claims.

The PhD viva can last between one and four hours - usually two - so it's necessary to pace yourself to get off to the best possible start.

Remember, the examiners aren't trying to trip you up - they want you to pass and are primarily there to hear you talk about your project. So, after the polite introductions they'll typically start with an icebreaker to put you at ease and help calm the nerves.

It's meant to be an open and honest conversation about your work, so feel free to politely disagree with the examiners, especially on areas you feel strongly about. Don't forget to use examples from your thesis to back up what you're saying, remembering to be clear and concise.

If you know your way around your thesis and can explain your thinking and way of working, this test shouldn't be a problem. And if you don't know the answer to a specific question - admit it, as it's better to concede your limitations in an area than ramble on and hope they don't notice you're struggling to come up with an explanation. No research is perfect, so it's important to appreciate this during the discussion - but don't be too overcritical about your work either, as that's not your job.

Finally, as the PhD viva can quickly move from a series of friendly questions to those that are more in-depth, take some time to think before answering. Don't worry about any periods of silence from the examiners, as this certainly isn't an indication that you're doing badly.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future. This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

Five top tips to pass your PhD viva

Research assistant Kirsty Devaney , who successfully completed her doctorate , provides five invaluable pieces of advice on passing the PhD viva.

First thing's first...what is the PhD viva?

Officially called the viva voce , meaning ‘living voice’ in Latin, the viva is an oral examination that sees a PhD student defend their thesis and showcase their knowledge to a panel of academic experts.

The viva takes place after you have completed your thesis and sees these experts ask you various questions to ensure you understand your work and have become an expert in your field.

Now, over to Kirsty…

1). Make your own learning space

"It's important on the lead up to the viva voce to have a space that's designated for your preparations. This could be at your university, in a coffee shop or at home.

"For instance, I took over my dining room table for a good two months. I had all of my resources there - my books, my thesis and lots of post-it notes."

2). Take some time away from your thesis

"I had a three-month wait in between submitting my thesis and sitting my viva, but I knew I couldn’t spend that time prepping as it would be far too intense. I took a full month off from revising and returned with a clear idea of what I needed to do."

3). Make a plan of action

"A month before my viva, I made a list of things I wanted to achieve before the day.

"One was to read through my thesis in full three times. I also committed to tabbing all of the important chapters, diagrams and data in my thesis, so I could refer to them quickly if needed.

"I then compiled a series of questions which I thought might come up in the viva and put them all into a pot. Once I’d got enough questions, I’d ask my husband to pull out one of the pieces of paper at random and ask me the question. 

"Some days I would also catch up on any recent literature I may have missed that could be relevant.

"All of this proved incredibly useful for when my viva arrived."

4). Know your examiners

"When you’re close to completing your doctorate, you might have a conversation with your supervisors about the people in the field who might be external examiners.

"Once you know who they are going to be, it’s really important to get to know their research, what their research interests are and what methodologies they use."

5). Become the expert

"BCU does a mock viva, which I found incredibly helpful as it meant I could work on any difficulties I faced.

"One issue that arose from my mock was that I had to become a lot more confident and assertive about my research and my findings.

"When you walk into the room to do your viva, you are making the leap from being a student to having the certainty of an expert."

How scary was the PhD viva?

Kirsty, who also runs the successful Young Composers Project , says it’s important not to be too fearful of the examiners.

"They are there to challenge you, but they’re not trying to be mean for the sake of it,” she explains. “They want to make sure you know your stuff and haven’t just plagiarised the material.

"However, it’s important to breathe and take your time – they’re not expecting rapid-fire responses."

Kirsty credits the support of the  School of Education and Social Work  for getting her through her PhD.

"They really got it right,” she says. "They have been incredibly supportive. I never felt alone."

How to survive a PhD viva: 17 top tips

Just handed in your PhD thesis? Now it’s time to plan for the next hurdle: a viva. Academics offer their advice on how to best prepare

• Finishing your PhD thesis: tips from those in the know
• The key to a successful PhD thesis? Write in your own voice
• PhD: so what does it really stand for?

H anding in your PhD thesis is a massive achievement – but it’s not the end of the journey for doctoral students. Once you’ve submitted, you’ll need to prepare for the next intellectually-gruelling hurdle: a viva.

This oral examination is a chance for students to discuss their work with experts. Its formal purpose is to ensure that there’s no plagiarism involved, and that the student understands and can explain their thesis. It involves lots of penetrating questions, conceptually complex debates and is infamously terrifying.

How can PhD students best prepare? We asked a number of academics and recent survivors for their tips.

Preparing for the viva

1) Check your institution’s policies and practices

Institutional policies and practices vary. Find out who will attend your viva (eg will a supervisor attend, will there be an independent chair?) and what their roles are. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

2) Re-read your thesis – and keep up-to-date with research

Don’t underestimate the amount of time the examiners will have spent reading and thinking about your thesis – however, you should remember that you are still likely to be the “expert in the room” on this particular topic. Check to see if any relevant recent papers have emerged since submitting the thesis and, if so, read these. Dianne Berry, dean of postgraduate research studies, University of Reading

3) As an examiner, you tend to stick to things you’re an expert in when driving the questioning

Your viva panel will consist of an external expertise in your subject area and an internal which may be in a subject field associated or directly related to yours. The external examiner is the one who mainly calls and fires all the shots and so it’s pretty important to have a knowledge of their published contributions, especially those that are related to your thesis in any way. Dr Bhavik Anil Patel, senior lecturer in physical and analytical chemistry

4) Think about what you will or won’t defend

Consider carefully what you will defend to the hilt in the viva, and what you are prepared to concede. It’s important to defend your claims about the originality of the thesis and its contribution to knowledge. However, no research is perfect, and showing that you have considered what could have been done differently, or even better, is not a bad thing. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

5) Draw up lists of possible questions – especially ones you dread

I collected questions from a bunch of different places ( listed here ) which I then tailored to my PhD. Somebody I worked with also recommended that I put together my 10 nightmare questions. I found this really useful, by writing down and thinking about my dreaded questions, they were no longer so bad – it was almost as if I’d faced the beast.

Generally speaking, I was able to predict the questions that I was asked. There were a couple that were unexpected but they were either conceptual points or based on literature that I just didn’t know. Richard Budd, research assistant, University of Bristol who sat his viva in summer 2014 and has blogged about the experience

6) It’s not like sitting at a laptop where you can edit a sentence as you go along

By the time you finish your PhD you’ll know your thesis inside out. One of the things you won’t be as practised at is talking about it. When I was preparing for my viva, I practised vocalising answers. It’s not a case of needing to learn to answers verbatim – this would only work as a technique if you could guarantee the exact way your examiner will ask a question – but it is about thinking about how you will articulate certain things. A viva isn’t like sitting at a laptop where you can edit a sentence as you go along. Richard Budd, research assistant, University of Bristol who sat his viva in summer 2014 and has blogged about the experience

7) Bring a printed copy that is exactly the same as that of your examiners

Ensure you and your supervisor have a printed copy that is exactly the same as that of your examiners (specifically the same pagination). Mark with tabs the key sections and highlight for reference important quotes and points you might want to refer to. If you have some key diagrams it may help to have these printed larger on A4 sheets that can be used in a discussion.

There is a chance, albeit slim, that an examiner will wish to see some piece of experimental data, software, or other supporting evidence. Have this all neatly archived and accessible. You can do this after submission. Anthony Finkelstein, dean of the UCL faculty of engineering sciences who has blogged about surviving vivas

During the viva

8) Get off to a good start

Give a few detailed answers in the opening 15 minutes, demonstrating knowledge, describing your thinking and working - then the examiners are likely to relax into the viva. If the first few answers are short and non-specific, not demonstrating knowledge, this can begin to raise concerns, and that can set the tone for the whole viva. This is avoidable. Rowena Murray, author of How to Survive Your Viva: Defending a Thesis in an Oral Examination

9) Prepare for the icebreaker

Every viva opens with that dreaded icebreaker that is supposed to break you in gently but often seems to be the thing that gets students into a pickle. It’s so basic, students almost forget about it. Most often this would be to give a five to 10 minute introduction to your work and your key findings. This is such a common question that not preparing for it would be silly. Dr Bhavik Anil Patel, senior lecturer in physical and analytical chemistry

10) Silence doesn’t mean bad news

Don’t assume that you will be given any indication of the outcome at the start of the viva. The examiners may or may not offer comments on the thesis at this stage and candidates should not interpret a lack of comments at this point as a negative sign. In some cases institutional policy prohibits it. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

11) Don’t point out your own weaknesses

Avoid shooting yourself in the foot by highlighting the weaknesses in the thesis by being overly humble (eg “I didn’t think this would be an acceptable piece of research given the way I handled x or y”) or by saying what you “failed to achieve” or “did not manage to carry out in a robust manner” etc. Leave that to the examiners to pick up in their reading, they don’t need help. Dr Mariana Bogdanova, lecturer in management, Queen’s University Belfast

12) Don’t talk like a politician There’s a danger of trying to over-prepare. Don’t learn answers off by heart – it removes the spontaneity and is obvious to examiners. If a student has pre-prepared answers they become a bit like politicians, answering questions they weren’t asked rather than the ones they were. I have come across mixed views on mock vivas. Some people really like them – and they can settle nerves – but other times it can remove spontaneity and steal your thunder. Jerry Wellington, head of research degrees at University of Sheffield and author of Succeeding with Your Doctorate

13) You may need to move from friendly questions to complex debates

Vivas can appear friendly and then suddenly go very conceptually complex. The language used is an alternation between accessible normal language and really specialised arguments. The student needs to be able to move orally between the two. Gina Wisker, professor of higher education and contemporary literature at Brighton University

14) If things get on top of you, use the excuse of having a look at the thesis

Make sure that before the viva you get plenty of sleep, eat properly and de-stress. If things get too much when you’re in there, use the excuse of having to look something up in your thesis. You could also pause and say “Can I write that down for a moment?” Stall for time until you get yourself back together again. Gina Wisker, professor of higher education and contemporary literature at Brighton University

15) Focus on your contribution

One of the most important things that the examiners will be looking for in your thesis, is the “contribution to knowledge”. It is the contribution which makes your work doctoral level. Be sure that you understand exactly what your contribution is, and that you are able to express and explain it clearly and concisely.

Write it down in a paragraph. Discuss it with you supervisor and fellow students. Make sure that you can relate your contribution to other work in your field and that you are able to explain how your work is different. Peter Smith, author of The PhD Viva

16) Expect your viva to last between one and three hours

Students frequently ask how long the viva is likely to be. Obviously they vary. Discipline differences are important. Our research suggests that most natural and applied sciences vivas were completed in one to three hours, whereas arts, humanities and social science vivas were typically less than two hours long. In the natural and applied sciences 43% of vivas lasted two hours or less, compared to 83% in arts, humanities and social sciences. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination Process: A Handbook for S tudents, Examiners and Supervisors

17) Enjoy it

The best advice I ever got was “Try to enjoy it”. It seemed ludicrous at the time, but I actually found myself really getting into the discussion as the viva went on. It’s one of the earliest chances you get to talk to someone who not only informed your research (ideally) but is also conversant with your own. It’s a great chance to explore the contours of your research – treat it as such, and it doesn’t seem quite so daunting. Michael James Heron, school of computing science and digital media, Robert Gordon University

Hopefully you will have had some experience of discussing your research either in seminars, progress reviews, or at conferences and you can build on this when preparing for your viva. Supervisors may offer the chance to do a practice, or mock-viva, which can be a very useful experience.

Reminding yourself that you are the expert in your research, and anticipating a range of possible questions will help you prepare thoroughly for having a good viva. The advice on this page offers further suggestions and strategies for viva success.

A viva voce is an oral examination (usually referred to as a viva). In some courses, students are given vivas as part of the undergraduate or Masters assessment process. However, it is more usually found as part of the final assessment process for PhD students.

Its main purpose is to assess your research and subject knowledge . The viva will generally be conducted by an external examiner and an internal examiner. Although the format may vary, it will involve a discussion of your research topics and conclusions. You will be asked questions that will give you the opportunity to show the examiners your research skills and the originality of your ideas.

In some academic cultures, this examination is known as a 'thesis defence'. However, in the UK, it is more commonly seen as a dialogue: an opportunity for you to explain and expand on your research to examiners who are experts in your field.

Format  - Make sure you know what the format will be. It may be helpful to look at the University's Rules for Submission of Theses and Guide for Examiners of higher degrees by research (link below). The Doctoral and Researcher College's 'Surviving the Viva' guide also has more explanation of the specific procedures here at Reading, and can be found as part of their Guides for Students. In addition, talk to people who have recently gone through the viva process in your department. Your viva will not be exactly the same as theirs, but it will give you a better idea of what might happen.

Prepare - It is crucial that you prepare well for your viva. This will help calm your nerves and also ensure that you make a good impression on the examiners. Know your thesis well; reread it and annotate it - you will be expected to take a copy into the viva, and it will be helpful if you can find key areas quickly. Also keep reading the latest research in your field - this will keep you aware of current developments and stimulate your thinking. If you find something new that you think you should have included, don't panic - just make a note and be prepared to talk about it in the viva.

Practise - Ask your supervisor if it is possible for you to have a practice viva. This will help you familiarise yourself with the whole process. For more suggestions about speaking in public, see our LibGuide on Giving presentations .

Who is your examiner?  - It will help you to feel more confident if you know a bit more about who will be examining you. Find your external examiner online and make sure you're familiar with their area of expertise and publications. You will not be expected to tailor your thesis to your examiner as it is your project and it should be able to be examined by anyone with sufficient expertise in the field. However, knowing your examiner's own research preferences may help you to see what areas of your thesis they will be most interested in discussing. Finding a photograph may also help to calm your nerves.

Make a list of possible questions - There may be obvious questions you're likely to be asked, and preparing the answers to these questions is always helpful. Some of the broad questions that most vivas will cover are:

• "What have been the significant contributions of your research?
• "What would you do differently if you were setting out to do it today?"
• "Where do you see this kind of research moving in the future?"

You might also want to think about anything in your thesis that is controversial or new. What would you say if you were asked about these?

Often the examiners will want to put you at your ease as much as possible, so may start with a general question to help calm you and establish a good relationship, for example:

• "Tell me about your research"
• "What motivated you to do research in this area?"
• "How did you develop an interest in this topic?"

These type of questions can be unnerving, even if they are not intended to be, as they seem very broad and simple. Think about how you might answer them clearly and concisely to get the viva off to a good start.

There are more examples of potential viva questions in the Graduate School's 'Surviving the Viva' in their Guides for Students

Explain it to a friend - When you've been working on a complex project for a number of years, it can be hard to see the bigger picture. It can help to get your ideas straight in your head if you have to give a simple explanation to someone outside of your topic.

Don't rush your answers - Take your time. Listen carefully and allow yourself time to process what the examiner has said, or ask for clarification. Your examiners are not expecting (or wanting) you to jump in with an answer as soon as they have finished speaking. Have a drink of water, or use phrases such as 'That's a good question' to give yourself time to think.

Discuss and explain - Don't answer questions with 'yes' or 'no', but justify your comments with examples or evidence. Some questions may explore areas of your thesis that show weaknesses. This is normal; your examiners are not expecting perfection and they recognise that all research has limitations. They want to see that you have thought about any weaknesses, the reasons behind them, and how these limitations may be overcome in future. Therefore, it is important to consider and explain any weaknesses, as opposed to trying to dismiss or hide them.

Answer with confidence but don't be defensive . The examiners are likely to challenge you in a constructive way and press you to justify your approach and findings, but they are not there with the intention of failing you - they want to hear what you have to say about your work.

Stay calm - Don't forget, this is the one exam where you are likely to know more about the subject than those giving the marks! The examiners want to get the best out of you. As long as you do the preparation, you'll be fine.

• Advice on vivas from the THES A useful article with tips from an academic experienced in examining theses.
• What happens in a viva? A short video made at the University of Reading to show what a viva might look like and offer some tips for the day.

In some cases you may be told the result of your viva straight away, but more often the examiners will ask you to leave the room and wait nearby while they take a little time to discuss before making a decision. The four possible outcomes are:

• The degree will be awarded 
• The degree will be awarded subject to minor corrections (to be completed within three months) 
• The student is required to make major amendments (to be completed within 12 months)
• The student will not be awarded the degree for which the thesis is submitted (in some cases the examiners might award an alternative degree).

It is very unusual to pass without any changes - almost everyone has to make some revisions.  

The outcome of a viva is not usually a clear pass / fail result. Nearly all students will have to make changes, ranging from minor corrections to major amendments. Being asked to make revisions means having the chance to improve your work in light of the comments of experts in your field - it does not mean you have 'failed'. It will also strengthen your work for the future.

Understandably most postgraduate students see their viva as the end of their PhD journey, but for almost everybody there will be a few more steps to go. It may be difficult for you to get back into working mode when you thought you had finished. Below are some suggestions to help you manage your corrections and revisions, and get your changes done.

Allow yourself some time off

Give yourself a chance to recover and refocus on your goals Remember your reasons for doing a PhD and use these aims to motivate yourself in the final stages

Get another perspective

Having been involved in intense study activity (and probably anxiety) in the run-up to your viva, it is not surprising if you find yourself feeling quite emotional and even confused afterwards. This can be the case whether you have passed without corrections, have minor amendments or major revisions to complete.

Many students have found that talking to someone who has not been involved can help to put the whole experience into perspective. This might be a Study Adviser, who can also help with your organisation and time management to get revisions completed, or someone from Student Wellbeing.

Get the list of corrections

The examiners will produce a list of the changes they require you to make. This will usually be forwarded to you from the Examinations Office or via your department.

Make sure you get this as soon as possible, as you will need to demonstrate that you have made all these changes satisfactorily; it will form the basis of what you do next.

See your supervisor - soon

Talk through with your supervisor what you plan to do for each correction, and check that this is what is needed. Arrange a deadline for making the changes and confirm that your supervisor will be available to give feedback on your changes.

You and your supervisor may decide that a fresh perspective is needed, so your supervisor might suggest a colleague that could advise on the corrections.

Clarify what you need to do

Check with the examiners (if possible) or your supervisor (if not) what they want for each correction. For example does "Expand on method in Chapter 3" mean write a few more sentences explaining the method, or add a whole new section to Chapter 3 going through the methodology in fine detail?

Draw up a timetable

Normally, minor corrections have to be made within 3 months, and major amendments need to be made within 1 year of the viva.

Draw up a realistic timetable for making the changes – taking into account outside pressures like your funding ending, returning home, finding a job, family commitments. Just like when you were writing the thesis, break the corrections into tasks that need to be done, and set aside specific times when you will do them.

Don't leave it too long

Although you might not want to look at your thesis ever again, it is better to get going while it is fresh in your mind. The longer you leave it, the harder it is to get started again.

• Start with the smaller tasks that are easier to complete, like correcting typos, to get back into the flow of working.
• Recognise when you are procrastinating and overcome this by setting yourself small goals and rewards.

Stay focused

Don't agonise about getting changes "perfect" and reworking the whole thesis. At this stage you need to be clear what the examiners want and give it to them. Be thorough, but be efficient. It is well worth spending time getting the corrections right as they will strengthen your thesis, but also recognise when you may be going beyond the bounds of what is required, and try to be as business-like and objective about making the corrections as you can.

Check the changes with your supervisor

You don't want to have to make any further corrections after your resubmission, so check with your supervisor that you have covered everything the examiners require.

Your supervisor may be able to point out places that you can strengthen or reword to ensure you meet the examiners' criteria.

Once you and your supervisor are happy that you have made all the necessary corrections and completed them thoroughly – resubmit the thesis.

Ensure you are clear on the University procedures for resubmission – the examiners may have the option of asking for a second viva.

Remember: In years to come no one will ever ask you about your corrections. Many top academics had to make major changes to their theses and this has helped, not harmed, their careers.

• Student wellbeing Online guides, Life Tools talks and counselling appointments.

Appeals are possible in the case of irregularities in the examination procedure, exceptional circumstances, or evidence of prejudice and bias. Appeals cannot be made against the academic judgement of examiners. Check the University procedures for appeals (which can be obtained from the Examinations Office) and contact your supervisor or department if you are considering appealing. You may also find it helpful to discuss your reasons for appealing with a Reading University Student Union Student Adviser who will be able to give you confidential advice on your appeal options.

5 Tips for Preparing for Your PhD Viva

• By Zebastian D.
• December 13, 2019

You’ve just passed a massive milestone: writing and submitting your PhD thesis. This has been the culmination of at least three years of work and is definitely a cause for celebration. But the journey’s not fully over just yet – you still have the viva to pass. In the UK the viva usually lasts a few hours and involves a detailed discussion of your thesis with two expert examiners; your primary supervisor may or may not sit in this. Expect the viva to be tough – you’ll need to be able to defend your PhD thesis and respond to questions designed to probe your understanding of your subject. But if you prepare for it well, you’re likely to come out of it having had an enjoyable experience discussing your work with people genuinely interested in your project.

Here are some tips to help you prepare for the day.

1. Know Your Thesis

You should expect your examiners to have spent a considerable about of time going through your PhD thesis and the content of it will be fresh in their mind; make sure it’s fresh in yours too. Yes, you’re the one that’s written it but, if you’ve planned well , you may have written some of your chapter content quite a while ago. Equally, I would definitely recommend checking to see if any new papers in your field have been published since writing your chapters and submitting your thesis.

2. Know Your Examiners

Your examiners will be experts in their fields, and at least one (if not both) will be experts in the same field of your research. Make sure you look up papers they’ve published and think about how they fit in with your work. It’s likely that some of their line of questioning in the viva will be based around their contributions to the research area.

3. Think of Possible Questions

It’s a good idea to spend time with your supervisor to think of possible questions the examiners may ask you. In particular, can you predict the tough questions that might come your way and how you might best answer them? Are there any areas within your work that you would consider as limitations for your studies and that you should be prepared to acknowledge? Some preparation here and even a mock interview will go a long way in making the actual thing feel easier.

4. Bring a Copy of Your Thesis

Make sure you have your own printed copy of your PhD thesis that you bring along with you to the viva. Make notes and highlight pages and sections within it that you especially want to bring attention to. You might also find it useful to print separate larger copies of key results (e.g. graphs or figures) that you think would be useful to discuss. Some props that help explain concepts (if relevant) can also be a brilliant way to guide the discussions to areas you’re most comfortable with.

5. Focus on Your Strengths

Try to view the viva as an opportunity to showcase the new knowledge you have added to your field of research. Focus on the positives that have come out of your work; all projects will have some areas of weakness but there’s no need to highlight these to your examiners unless directly asked about them. Coming into your viva with one or two papers published (if possible) is a great positive – it’ll give you confidence that your work has already stood up to peer-review and is a very good way to present your contributions to research.

Learn about defining your workspace, having a list of daily tasks and using technology to stay connected, all whilst working from home as a research student.

The scope of the study is defined at the start of the study. It is used by researchers to set the boundaries and limitations within which the research study will be performed.

What is a PhD Viva Like? Sharing Graduates’ Experiences

When you’re trying to prepare for a PhD viva it can be really difficult to know what to expect. Unlike pretty much every other exam you’ll have experienced, the viva isn’t a standardised exam so you won’t find any past papers to practice on!

In this post I’ll be sharing the inside scoop on what a PhD viva is like. Both from my own experiences plus those of a few other PhD graduates.

Preparing for your viva? You may also want to take a look at some of the other PhD viva content I’ve written:

How to Defend a Thesis: An Introduction to the PhD Viva

Common phd viva questions.

Note: Every viva is different, in this post I’m focussing on my viva which took place in the UK. Two PhD graduates in Spain and the US also share their experiences.

What is a PhD viva?

For those who aren’t already familiar with what a PhD viva is, I’d highly recommend reading my full post on How to Defend a Thesis: An Introduction to the PhD Viva . This delves into how a PhD viva is assessed, who is present, the potential outcomes and what follows after.

As a quick recap, a PhD viva (also called a defense in some countries) is the final assessment a PhD student undertakes in order to pass their PhD. The format the viva can take varies from country to country and even institution to institution, but it typically involves discussing and defending your PhD thesis with experts in your field.

In this post you’ll hear about the viva experiences of three PhD graduates, each with a slightly different format.

To get the best understanding of how PhD vivas take place at your university I’d recommend:

• Checking out any webpages your university have which formally outline the viva process
• Speaking to your PhD supervisor
• Chatting to colleagues such as postdocs who’ve been through it

Viva Experiences from PhD Grads

Prof elizabeth bondi-kelly , phd from harvard university, usa. assistant professor in computer science at university of michigan.

What was your PhD viva like? At my (virtual) defense, I had my committee, adviser, labmates, and family/friends. I was fortunate to give my job talk presentation again for my defense, so I had already had a lot of practice with presenting it and being asked questions about it.

How do you suggest people prepare for their PhD viva? For anyone who hasn’t had that opportunity, I highly recommend practicing to get a polished talk and practice answering questions about it.

Prof Raúl Santos-Rodríguez , PhD from Universidad Carlos III de Madrid, Spain. Full Professor in AI at University of Bristol.

What are PhD vivas like in Spain? The viva process in Spain varies from university to university. In most cases there are a few previous filters (internal/external reports) that make it such that, once you are through those, most of the pressure is off for the actual defence. The viva consists of a public presentation (usually with colleagues, friends and family in the audience) followed by questions from a panel, with each member asking their questions in turns. Both presentation and Q&A tend to be time limited (around 45 minutes each). 

What was your PhD viva like? My viva experience was nerve-wracking but rewarding too. I remember how the exercise of putting together the presentation with the panel in mind actually gave me quite a different perspective on how to tell the story of my thesis. The event took place in a rather formal lecture room in our faculty. The panel consisted of five examiners (three externals including one from abroad, and two internals), all of whom were experts in my field of study. The panel asked me a wide range of questions, covering both very specific details and very high level matters. Once I answered their questions to their satisfaction, and after a short deliberation, I was given the good news. Overall, I found the viva to be a challenging but stimulating experience — and a good memory.

How do you suggest people prepare for their PhD viva? In terms of advice, I would suggest to:

• Expect to be surprised by unexpected questions about your research
• Be clear and concise, allowing examiners to ask for more details if needed
• Practice your presentation without being constrained to say the same things every time
• Not be afraid to ask for clarification if you don’t understand and take your time to respond
• Enjoy the interaction with the examiners as they are experts that have a lot to add to your work

Me! PhD from Imperial College London, UK. Research Fellow in AI at Bristol.

What was your PhD viva like? My viva, which took place over Microsoft Teams, included just an internal examiner, external examiner and myself. I gave a short presentation giving a summary of my PhD then about five hours were spent giving suggestions to improve content I was preparing to submit to journals. It was much less intimidating than I was expecting.

How do you suggest people prepare for their PhD viva? I mainly suggest to not over prepare! Sure, reread your thesis and swot up on any content you don’t feel comfortable describing (for instance certain techniques you’ve used), but I would caution against rehearsing too much: come to terms with the fact that you won’t be able to predict all the questions you’ll get asked.

I’ll be sharing more details on my viva experience in the rest of the post.

How To Prepare For a PhD Viva: The Advice I Was Given

Ahead of my own viva I typically got told to:

Relax and take your time in replying . This is somewhat sensible advice but a bit like telling someone to calm down: it doesn’t always work. Furthermore, relaxing can be hard to do when you also get told to…

Be prepared to answer questions about every part of your work . At face value this can seem reasonable: if you did the work, and deserve a PhD, you should be able to explain your work. Like many of us I heard the horror stories of examiners asking students to provide an explanation of fundamental techniques from first principles such as: “derive energy”!

However, I don’t think any rational examiner can expect a student to be able to answer every possible question about their PhD work. Not least because many students aren’t relaxed during the viva and instead are filled with nerves.

Thankfully, the reality is that examiners simply need to check that you’ve done the work and understand it. Therefore, yes you should be able to give a broad explanation of the techniques you’ve used but you can’t be expected to know everything about every technique.

Once it strays from your work to underlying principles I suggest that you explain as much as you feel comfortable then push back – the internal examiner (who acts as a moderator) should also step in if unreasonable questions are being asked. For more details on what PhD examiners are looking for, read this section of another post I’ve written .

How I Prepared for My PhD Viva

The time between submitting my thesis (14th February) and viva (25th March) was shorter than for most people. On top of that I didn’t spend long writing my thesis, meaning that the time between finishing my actual research and my viva was pretty short (around two months). Therefore I didn’t feel the need to “revise” for my viva. As in, sometimes you’ll hear of people reminding themselves of how certain experimental or analytic techniques work, but it was pretty fresh in my memory.

Instead, about 48 hours before my viva I started to read through my thesis. This is going to sound really bad but this was actually my first (and only) time properly reading through my thesis. No, I didn’t outsource or use ChatGPT to write my thesis!

When I submitted my thesis I had of course assembled all the chapters but had never given it a proper cohesive read all the way through. I read through the thesis over the course of 4-5 sittings. Reading fiction is definitely more fun .

I personally didn’t prepare by trying to come up with answers for lots of potential questions. But if you’re keen to have those to hand, read my Common PhD Viva Questions .

Preparing for your own viva? I’ve created a set of viva preparation worksheets which are available for free in the resource library. Click the image below for access!

Why didn’t I prepare more?

I felt pretty relaxed about my viva. This isn’t because I am crazy clever or knowledgable. In fact, like many of us I’ve felt imposter syndrome, waiting for the moment that my lack of knowledge gets discovered: and if there ever a moment you’d expect this to happen it would be at your viva.

These three things relaxed me for the viva:

• The external examiner seemed nice from the time I’d met him in the past at a conference. Certainly not a sure-fire sign that he wouldn’t turn into a scary beast during a viva but it seemed like a good starting point.
• It was virtual. My viva took place right at the start of COVID and as such took place over Teams. For some reason this felt reassuring, as if I could get away with just unplugging my internet connection if they asked anything particularly scary. Thankfully I didn’t ever feel the need to try this out!
• I had published PhD work in a well-ranked respected peer-reviewed journal. This was far and away the most reassuring thing. As mentioned in another post, examiners have to be confident in all of the following things to let you pass your PhD viva. If you have published some of your work somewhere respectable you tick many of the boxes immediately:

Oh, and I also didn’t prepare much because I was preoccupied with moving from London the week before my viva because of COVID and the start of lockdowns. Unexpectedly I ended up moving in with my girlfriend’s parents. It was rather chaotic but probably a useful distraction too.

My PhD Viva Experience

Who was at my viva.

Unlike vivas in other countries, such as the two international experiences shared above, a viva in the UK usually only involves:

• PhD student – me in this case!
• Internal examiner – an academic working in the same research area from the host university. They’re there to moderate the discussion and check that the university’s viva regulations are followed.
• External examiner – another academic working in the research area from a different university. In my case this was someone who was a leader in the field who came from another UK university.

Optionally the PhD student may ask their supervisor to attend. I’ve known of a few people who’ve had their supervisor there too, though it’s pretty rare and unnecessary in my opinion.

How long did my PhD viva last?

All in all it was about five and a half hours.

This was much longer than I anticipated. When we scheduled the viva to start at 10am I naively expected us to be finished by lunch. Admittedly the examiners did suggest stopping for a break at lunch time but again I naively thought we’d be done shortly afterwards, so declined the opportunity for more than a 5 minute comfort break. In the end we finished up around 3:30pm.

How was my PhD viva structured?

• Introductions (2 minutes) . I’d actually never met my internal examiner (who should act as a moderator) so introductions were necessary.
• Presentation (10 minutes) . A few weeks in advance of the viva I asked whether or not the examiners would like a presentation, and if so of what length. They said yes, 10-12 minutes. My supervisor strongly suggested making it on the shorter side: short and snappy is good and you’re about to have hours to discuss the details.
• Discussion (5 hours, yes, really!) . More on this in a moment.
• Decision and final comments (10 minutes) . I was asked to leave the metaphorical room (Teams call, remember!) and after a few minutes was invited back in after which they told me I’d passed with minor corrections. They gave a summary of the next steps, which were mostly administrative with paperwork, and briefly went over what changes/corrections they were expecting to the thesis.

What did we discuss for five hours?

Before my viva I had visions of it being like a job interview that lasts for hours and hours. They ask a slightly tough or awkward question, you try and answer, rinse and repeat x 100. The reality was really different.

The experience was much less intense than I was expecting. The examiners said from the outset that they were happy with the quality of the work and just aimed to give feedback to improve both the thesis and publications.

The vast majority of the viva was spent going page by page through the thesis covering points that the examiners had written down: not questions, merely suggestions. Very little of the viva involved me getting questioned: most of what I said was probably along the lines of “I agree, that’s a great idea”.

The examiners commented that they liked the [short] length of the thesis (140 pages before references) which may have helped. I was expecting at least a few dodgy questions such as explaining the content of a particular reference or deriving something from first principles. In all honestly I’m not sure I’d have been prepared for some of this, so was fine with not getting a hard time of it.

There were very few questions in general which was somewhat of a relief, though I was kind of looking forward to more of a discussion around the project. There were only two actual questions I think I got asked: one explaining why a particular technique wasn’t representative, and secondly a much more fluffy question of what would I do differently if I was starting again. That was it. I was really expecting more questions.

Every viva is unique so I can’t claim that my experience is representative but I will say that it was a relief to get through it unscathed.

What I wish I’d done differently

Asked more questions myself . The viva is one of the few times you’re likely to have hours of access to academic experts with such a keen interest in your work.

Was it tiring?

A little, just as any meeting which lasts over five hours would be. But because I didn’t feel like I was actually getting quizzed the whole time it was nowhere near as tiring as it could have been. Mostly I was tired just from having to pay attention for that long: I usually don’t sit still for more than 20 minutes!

What happened afterwards?

My viva was in March 2020, at the start of lockdown. I’d moved from London just the week prior and had to cancel the scheduled celebratory drinks with colleagues. So instead I had a glass of champagne with my girlfriend and her parents (who I was staying with).

After that, I got cracking right away the next morning on making the examiners’ suggested changes to my thesis.

How do i prepare for a phd viva, phd viva presentation, phd viva questions.

It is a matter and pride great amount of pride to get done with your Ph.D. degree. A great number of efforts goes into making it happen. But preparing dissertations, thesis and getting it reviewed by the panel is no less than a herculean task. Even though you are done with preparing your thesis, yet the journey continues. There exists one big task to complete or to say a bridge to cross before finally getting your thesis approved and being conferred with the doctorate. This essential part during the doctorate or Ph.D. program is the viva. After you have prepared your thesis, the next step is submission to the panel wherein it will be reviewed and the student will be intellectually tested for their knowledge that they have put into the process.

Passing through this hurdle will ensure your doctorate degree which requires little more labor and a lot of sharp wits. So, before heading on to discuss how one can manage or survive the rig-ours of Ph.D. viva let’s take a sneak peek through the actualities of why the viva is conducted and later move towards tips and tricks to ease the entire process:

Why is a Viva required?

Viva is an oral examination wherein students are tested on their thinking caliber in front of a big panel of experts. The primary purpose of a viva is to understand how much does the student know about the topic and to understand their level of contribution. Well, doesn’t that make you read through your work and prepare well for the viva before getting through the actual process?

What does Viva include?

As any other viva session, a Ph.D. viva includes a lot of question and answers with you on the latter side of the panel. The thesis prepared by you will be thoroughly reviewed by experts right from the topic to the format. The formal purpose is to have a direct discussion with the students to test their knowledge of the subject.

Ph.D. being an important degree and thesis being the most essential aspect of the course. Thence one cannot deny its level of crucial and importance. Viva also includes Ph.D. viva presentation wherein the student will be required to prepare a PowerPoint presentation surrounding the topic. The PowerPoint presentation will include all the minute points and details most importantly those points which you wish to highlight in your study, mentioned in a gist. This not only makes the entire process less cumbersome or writing, preparing and presenting viva but also throws out light about the student’s knowledge of the topic.

Summarizing of the topic

The Ph.D. viva begins with the student asked to summarize the entire topic in a gist. The student must thus prepare themselves in advance to speak about your topic, the reason for choosing the topic, what does it convey. Additionally, it is recommended to read the entire thesis well before the presentation and viva, jotting down important points which can be put forth as questions. The summary will be the first ground to set your impression on the invigilator. The topics may also lead to debates, wherein your caliber and expertise in the subject will be tested further.

When preparing for Viva:

Be well abreast with the university’s terms and policies. Each and every institution and university have their own set of terms and conditions. Therefore, it is imperative to primarily read through the conditions and accordingly prepare yourself for the big day. You could also try to find about the panel that would be conducting the viva and get an understanding from peers about the kind of questions they pose and what to expect during the viva, which will prove to be cherry on the cake for your preparation.

• Go through your thesis

Go through your theses, but now not as a student but as a third person. This will help you see through the prism of your thesis and help you gauge any loopholes and whether the research is up-to-date. Moreover, never underestimate the time spent by the examiners in reading through your thesis. And thus, this calls for you to be an equal expert who can handle the questions tactfully.

Along with reading through your thesis, check whether there have been any recent papers which are published in the particular topic same as yours and if so, ensure to read through them to be abreast with the latest happenings.

• Hit the bull’s eye

During a Ph.D. viva, there are usually two examiners who would be present during the process. One who is an external expert from the field, who is not usually from your university and the other an internal one who is a subject expert associated with your field. Your onus is to win the minds of both. It is usually the external examiner who will be shooting the questions. Thus, being pretty updated with the subject knowledge, reading about the contributors who are related to your topic in some way is the best way out for winning the doctorate.

• Prepare your answers

This is an important aspect of the viva and it all depends on how you defend your research.From this perspective, it is necessary to defend your point of view and claims, explaining your contribution and knowledge of the topic. Remember that no project is ever perfect, however, letting the examiner know you have contributed your best to the project is all the more important. For this, you can kick-start with anticipating some of the most sought questions and probable ones which you consider will be asked during the viva. Primarily looking for those which are most asked during a Ph.D. viva will ease your task to a large extent. Mostly the questions will be related to your literature review and conceptual points.

• Practice the technique of answering

Well, you are not going to get a chance for reading your answers from your laptop verbatim in front of the examiner. However, being well prepared like knowing the answers like the back of your hand is the most important aspect. Articulate your answers and try to present yourself an answer in the tone you would be using for answering the examiner.

• Take a printed copy of your thesis at the time of viva

It is always better to have an extra copy of your thesis present with you at the time of viva. In this copy, mark the important points and highlight them which you think might be useful at the time of viva. This will surely leave an impression on the examiner about your commitment to and involvement in the topic.

Now coming to what to do during a viva:

• First impression matters

The first few minutes of introduction is all that can create an impression. Therefore,,keep a calm demeanor with no pinch of nervousness (though it is bound to exist). You will be getting a total of 15 minutes to articulate your knowledge to the examiner regarding the project. You must hence prepare well for your answers which showcases your knowledge of the topic, thinking-process and more importantly your confidence.

Avoid short and non-specific answers, this can turn the whole viva upside down.Thus, ensure you break the ice of silence and march ahead in the journey of achieving the Ph.D. degree and adding the prefix of Dr. to your name.

• Do not think negative

Often examiners do not render comments to the students. This gets students into a pickle wherein they consider the answers to be either wrong or not so impressive to the examiners. Most often the institutional policy prohibits giving comments and sometimes the examiner notes it in the thesis remark.

• Be ready for a healthy debate

A presentation or viva might not always be a smooth ride. There might be moments of debates that would require you to showcase your prowess. So don’t miss the opportunity, answer each question tactfully. The student here must know when to be more tactful, conceptual and when to apply a friendly tone.

• When in doubt better to get it clarified

No one is a wizard and during the viva, there might be moments due to nervousness and a constant hit of questions when you need to look through your thesis for reference. Thus, herein you can ask your examiner for some time to write it down and during the time conceptualize your answer.

• No time bar

Be well prepared and know that your viva might go on for one to 3 hours or even more. So accordingly, be well prepared with your answers and focus on explaining and expressing your contribution to the topic in a precise and concise manner.

While it might seem stressful, a Ph.D. viva is quite easy if you have a good understanding of the topic and confidence in yourself.

So running through the whole points:

• Be confident
• Read through the thesis
• Mark important points

Be tactful with your answers to sail through the viva smoothly.

How to structure your viva presentation (with examples)

Most PhD vivas and PhD defences start with a short presentation by the candidate. The structure of these presentations is very important! There are several factors and approaches to consider when developing your viva presentation structure.

Factors to consider when developing a viva presentation structure

Structuring your viva presentation traditionally, structuring your viva presentation around key findings, structuring your viva presentation around key arguments, structuring your viva presentation around case studies, final thoughts on viva presentation structures.

A PhD viva or PhD defence is often one of the last steps that PhD students have to pass before receiving a doctorate. The viva or defence usually starts with a short presentation of the PhD candidate on the PhD thesis.

Presenting a whole PhD in a short amount of time is very challenging. After all, a PhD is often the result of several years of work!

It is simply impossible to include everything in a viva presentation.

Therefore, tough choices have to be made in terms of what to include, what to highlight, and what to exclude.

The structure of a viva presentation plays a crucial role in bringing across the key messages of your PhD.

Therefore, there are several factors to consider when developing a viva presentation structure:

• Available presentation time : Viva presentations usually last between 10 and 20 minutes, but every university has different regulations. Developing a structure for a viva presentation that lasts 10 minutes is different from developing one for a presentation that lasts 20 minutes or more. Thus, find out how much time you are allowed to present!
• The key contribution of your thesis: The structure of a viva presentation should reflect the content and key messages of the PhD thesis. For instance, if you have written a very theoretical PhD thesis, it makes no sense to structure your whole presentation around your data collection and analysis. Make sure that the viva presentation structure is in line with your main messages.
• University standards: It is recommended to discuss your ideas and plans for your viva presentation structure with others, as each university may have may be different (and even unspoken) rules and standards. Ask your supervisors about their preferred viva presentation structure. And talk to your peers who defend their theses before you.
• Clear storyline : Every presentation should have a logical structure which allows the audience to follow a crystal-clear storyline. This is also true for viva presentations. Thus, clarify your storyline and develop a presentation structure that supports it.

A very traditional viva presentation structure simply follows the structure of the PhD thesis.

This means that the viva presentation covers all parts of the thesis, including an introduction, the literature review, the methodology, results, conclusions, etcetera.

The advantage of this rather traditional format is that it provides information on each thesis chapter. Furthermore, it is relatively easy to prepare.

The disadvantage of this traditional format is that it is very challenging to fit all the information in a – let’s say – 10-minute presentation.

Furthermore, it can result in a presentation that is quite boring for the examiners, who have read the thesis in preparation for the viva.

One interesting way is to structure a viva presentation around the key findings of the PhD research.

For instance, you can select your three main findings which you each connect to the existing literature, your unique research approach and your (new) empirical insights.

A viva presentation structure around key findings emphasises the unique contribution of a PhD thesis, particularly in empirical terms.

A challenge of this structure, however, is to narrow down the presentation to a handful of key findings.

Furthermore, it might be tricky to find enough time during the presentation to discuss your theoretical framework and embed your discussion in the existing literature when addressing complex issues.

A viva presentation structured around key arguments is very similar to one that is structured around key findings. However, while key findings place more emphasis on the empirical data, key arguments operate at a higher level:

Arguments are sets of reasons supporting an idea, which – in academia – often integrate theoretical and empirical insights.

So, for example, your key argument 1 is your stance on an issue, combining your theoretical and empirical understanding of it. You use the existing theory to understand your empirical data, and your empirical data analysis to develop your theoretical understanding.

A viva presentation structure around key arguments is probably the most difficult viva presentation structure to choose.

However, if it is well done, it is probably the most academically strong and advanced way of defending your PhD.

Another common way to structure a viva presentation is around case studies or study contexts.

This structure is only applicable when the PhD thesis includes a comparative (case study) analysis, which is quite common in the social sciences and humanities.

A presentation can, for instance, first discuss the theoretical framework and research approach, then present Case 1, and then Case 2 or more if applicable.

A viva presentation structure around case studies can be easy to follow for the audience, and shed light on the similarities and differences of cases.

However, as always, you need to reflect on whether the structure supports your key message. If your key message does not centre around similarities and/or differences in cases, this is not the structure for you!

Every PhD thesis is unique, and therefore also every viva presentation structure should be unique.

The key to a good viva presentation is to choose a structure which reflects the key points of your PhD thesis that you want to convey to the examiners.

The example viva presentation structures discussed here intend to showcase variety and possibilities and to provide inspiration.

Never just copy a viva presentation structure that worked for others .

Always think about what fits best to your thesis, asking yourself the following questions:

• What is the main message of my PhD that I want to share during my viva?
• How do I develop a crystal clear storyline to bring this main message across?
• How can I structure my viva presentation to support and facilitate this storyline?

Ace Your Viva Presentation: Tips and Tricks

The thought of an oral presentation can be a huge source of stress and anxiety for many students, while some just blossom in such situations. If you’re one of the former, though, don’t panic. With decent preparation and practice, you too can successfully master your viva presentation.

But first: what is a viva presentation?

Viva voce is a Latin phrase most often translated as “by word of mouth.”  In academic circles, a viva presentation is an oral exam in which you defend your thesis.

After the thesis is defended, it’s discussed by a small panel. Among those present are the examining professors, but there may also be research assistants, members of the relevant department or even fellow students.

The purpose of this defense is to show examiners how knowledgeable you are on your research topic, that you have internalized what you have learned and know how to apply it.  In effect, it shows that you are well prepared to enter into academic discussion.

In principle, the viva presentation won’t make an entire grade’s difference, but it can tip the proverbial scale in your favor. It does offer some major advantages: You can clear up any ambiguities, assuage any doubts your examiners may have, and show that your stand by your research.

Preparation is key

After months or even years of hard work, the thesis is finished, the last formatting mistakes corrected, the bibliography painstakingly checked one last time and hooray, it’s finished! Time to celebrate! And then you get an invitation to the viva …

So, the wine bottle is re-corked and it’s back to the desk. But the good news is: you’ve actually already done most of the preparation. That’s what all the in-depth research you did to create your thesis was. You’re already an expert on your topic, so now you just need to explain it to your examiners clearly and calmly. That’s why it doesn’t make sense to start preparing for your viva before your thesis is finished and you’ve answered all your own questions.

Your supervisor should already know what to expect and the purpose of the viva is to present your results. Some people just hand in their thesis with huge relief and then put the whole thing out of their mind for a while.

This isn’t necessarily a problem but when the viva presentation is due, you really need to give yourself time to familiarize yourself with the topic again. Re-read your thesis a few times to get your results and methods fresh in your mind and you’ve already done much of the prep work for your viva.

Organizational details

You need to check the examination regulations of your institution to find out what will be required of you during your viva presentation. How long should the presentation last? Who will be present? How will the discussion group be structured at the end? Studies have shown that anxiety is significantly lessened if you know exactly what to expect. Don’t ignore these details.

Make sure you have the right power supply for the projector and whether your slide format is compatible with the projector. An article on slide formats and the difference between 4:3 and 16:9 can be found here .

Know how long your presentation should be. This often depends on what type of work you’re presenting. Be sure to keep this in mind as you create your slides.

Also, think about whether or not you want to provide a handout. Even if it isn’t explicitly required, examiners will often use a handout as a guide when asking their questions, allowing you to better control the discussion that follows.

You can find helpful tips on handouts here .

Lastly, think about what you’re going to wear for your viva presentation. If you’re not sure, take a cue from your examiners. If they wear a suit or dress to other viva presentations, it’s safe to assume that the dress code for your viva will be on the formal side. It’s important to look neat and tidy, but you should also feel comfortable. The wrong shoes or clothing that is too tight can negatively impact the way you present. You can find more helpful tips on clothing here .

Technical details

The most popular tool for giving a viva presentation is PowerPoint. On the day of your presentation, get there early to make sure your devices are working. It also helps to be familiar with PowerPoint’s features, such as Presenter View. This fantastic tool will help you stay on track during your viva presentation. For more information on Presenter View, click here .

In general, the rule for viva presentations is: Keep It Simple . This is a defense of your academic research and your slides should express that. Keep it classic and factual. Use a uniform font and a neutral, preferably white, background. You can use backgrounds from PresentationLoad:

In principle, you should use as little text and as few key points as possible, but it’s also essential to document your research accurately. Room for interpretation can be very dangerous here.

Naturally, it depends on the preferences of the examiners, but a little more text than in normal presentations is definitely allowed. If the nature of your work allows, graphics, photos or flowcharts are a good way to offer some variety and to clearly present complex issues.

How to structure a successful viva presentation

Like your thesis, your viva PowerPoint presentation should follow a certain structure. It is advisable to follow the structure of your thesis. After all, you have already given it a lot of thought and made sure that everything is in a logical context.

This way you can save yourself additional work. But remember – the presentation is not about retelling your thesis word for word. Just give the most important and interesting aspects.

Follow these points to create a solid structure for any viva presentation:

1) Relevance

Your thesis dealt in depth with a particular question, a specific aspect of research. In the first part of your viva PowerPoint presentation you introduce it and explain why it is relevant. What is the benefit for academic understanding, the general public, a specific avenue? Why this question in particular?

This allows you to show your audience why you chose your topic and why they should pay attention to what you have to say. All this needs to be supported by a professional introduction. You can find tips on how to do this here .

2) Background

This is where you set out the background of your research question in more detail, i.e. the most important theories and approaches that already exist on the topic, or which prompted your question. This helps your listeners prepare for any complex interrelationships, and clarifies the basis on which you have built your work.

In this part you set out how you approached your work. Was your research qualitative or quantitative? Did you conduct interviews, analyze data, evaluate a particular body of literature? This is your chance to show your examiners how carefully you worked and explain why you chose this particular method.

4) Findings

Now to present the results of your research. Were there any surprises? If so, how did you deal with them? Are the results consistent, where did you encounter difficulties, and how did you solve them? Use this section to talk about your research in a transparent and honest way. It’s an opportunity to show that you have dealt with the topic seriously and in depth, rather than just choosing the easiest way.

5) Conclusion

At the end, summarize your work clearly and concisely, and answer the research question posed at the beginning. You can also express your personal opinion as to whether you have achieved the result you expected or whether your research has come to a surprising conclusion.

Finally, you will need a well-rounded conclusion to your viva presentation. You can read tips for the perfect presentation ending here .

Whether you have to present your sources at the end of your viva is something to discuss with your supervisor or read up in the regulations. If in doubt, however, it’s better to be on the safe side with a list of sources.

Viva presentation: example

Since every viva is different, there is no one example of a great PowerPoint viva presentation. In our blog you will find numerous examples of how a well-structured and appealing PowerPoint presentation can look. For example, here . These should serve as a guide; it’s important to adapt the presentation to your personal requirements and your audience.

Make sure your narrative is clear and consistent throughout your presentation (as it was in your thesis).  It might be a good idea to ask your supervisor to show you good viva presentation example from previous years or to give you tips on where you should focus your attention.

General tips for a successful presentation

Almost there! You’ve created and double-checked your PowerPoint viva presentation and you’re feeling confident about your research work. For many people, though, creating the content is the easy bit; it’s the thought of speaking in front of others that terrifies them. It’s just a fact that in order to defend a thesis, you first have to be attacked .

1. Be prepared for critical questions and comments. Think through what possible aspects of your work might attract criticism, and prepare your rebuttals in advance. It helps to let friends or family read your work and ask questions.

2. The same friends and family can be amazingly useful as a practice audience. Deliver your presentation a few times in front of others and in a relaxed environment. This will help you feel more confident when it comes time for your viva presentation. Your trial audience may discover inconsistencies you’d missed, and can often provide valuable feedback on how your slides look, your speaking style or your body language.

3. Body language is very important when you’re giving your presentation; it can affect your persuasiveness. Stand upright (or sit if you need to). A small amount of movement can emphasize your engagement with the subject, but try not to look restless.  Getting your words across means you mustn’t turn your face away from the audience. Small gestures can underline your words, but too much fidgeting will look like nerves. 

Practising giving your presentation will soon get your body language expressing ease and confidence. To learn how to best prepare for a presentation, read our blog article on the right body language

4. Many people tend to speak far too quickly in presentations, probably to get the whole thing over as quickly as possible. While this is understandable, it means the audience misses half your words! Try to breathe calmly and speak evenly.

Time can seem to speed up when you’re in a stressful situation, so speak more slowly than you think right. And taking a proper breath in between phrases will help ground you.  You can find tips on how to prepare your speaking voice for your viva presentation in this blog post .

Your test audience can give you very good feedback here. When you practice your presentation, use a stopwatch to make sure that you stay within the given limits. Once you know that you won’t overrun even when speaking calmly, you can avoid the temptation to rush during the official presentation.

5. Pro tip: Do you have to give your viva presentation online? If so, some things will of course be different, starting with what program you use to stream your presentation. You can find out what options you have in this blog post . Click here to read more about what to pay attention to when giving an online presentation.

While knowing what you want to say is important, DON’T try to learn your entire presentation by heart. Even if you somehow did manage to, it would end up sounding artificial and you could be easily thrown off track if you miss a word or someone interrupts with a question. The best strategy is to memorize a few key points and speak freely.

Take a deep breath before you start and remember that you have no reason to be nervous. Nobody knows your work as well as you do; you’ve done all the research and can consider yourself an expert on your topic.

And if a mistake does happen, here are some tips on how to react to it with confidence.
