Exploring the Evidence: 7 Comprehensive Reasons Why School Should Start Later for Enhanced Student Well-being and Academic Success

The debate on the optimal timing for school start times has gained considerable momentum, presenting compelling reasons why school should start later. This growing consensus among educators, parents, and researchers highlights the profound benefits such a shift could have on student health and academic performance.

Traditionally, schools have adhered to an early morning schedule, a routine that is increasingly viewed as misaligned with adolescent physiological rhythms and conducive to chronic sleep deprivation. This discrepancy between school schedules and the natural sleep patterns of teenagers has sparked a significant reevaluation of how educational institutions can best support the developmental and learning needs of their students.

Advocating for later start times is not merely a call for more sleep; it represents a holistic approach to enhancing the educational environment by optimizing the physical and mental well-being of students. The argument for delayed start times is supported by a wealth of research indicating improvements in various areas of student life, including academic achievement, mental health, and physical wellness.

7 Reasons Why School Should Start Later

Wendy Troxel attributes the lack of sufficient sleep among teens not to Snapchat, social lives, or hormones, but to public policy, specifically early school start times, and shares insights from her dual perspective as a sleep researcher and a mother in a must-watch video on how this affects adolescents during a crucial stage of their lives.

Now, let’s delve into the compelling reasons why school should start later, exploring seven key factors that highlight the benefits of adjusting school schedules for the betterment of student health, engagement, and academic performance.

1. Improves Academic Performance

Adequate sleep is essential for adolescents, who are at a pivotal stage of development and learning. The evidence linking sufficient rest to improved academic outcomes is compelling, suggesting that later school start times could play a key role in enhancing students’ educational achievements.

The correlation between adequate sleep and enhanced academic performance is well-documented. Studies by organizations such as the National Sleep Foundation underscore the critical role sleep plays in cognitive functions, including memory retention, focus, and decision-making processes. Adolescents, who are in a crucial phase of brain development, particularly benefit from extended sleep, as it directly influences their ability to learn and excel academically.

A later school start time aligns with their natural sleep cycles, allowing for a more alert and engaged mindset during school hours. This alignment not only fosters an environment conducive to learning but also translates into tangible outcomes such as higher test scores and grade improvements. Consequently, the shift to later start times could serve as a strategic approach to bolster academic success, addressing educational priorities and student well-being in tandem.

Why It Is Important

• Academic success is key for future opportunities, shaping higher education and career paths.
• Enhanced performance from later start times correlates with better cognitive functions: memory, attention, and problem-solving.
• Quality sleep, aligned with circadian rhythms, leads to deeper, more restorative rest, essential for learning and memory.
• Alert, focused students are more likely to actively participate and retain information.
• Benefits individual students and contributes to a positive, productive learning environment.
• Later start times are a strategic approach to enhance educational outcomes and prepare students for success.

2. Allows Teens to Get More Sleep

The mismatch between teenagers’ biological clocks and early school schedules is a significant barrier to their health and well-being. Recognizing the critical importance of sleep for this age group underlines the need for adjustments in school start times to support their developmental needs.

Adopting later school start times harmonizes with teenagers’ biological clocks, addressing the mismatch between early school schedules and adolescents’ sleep needs. The American Academy of Sleep Medicine’s recommendations highlight the importance of adequate sleep for teenagers, a demographic often burdened by early start times and societal pressures that encroach on their sleep duration. This shift not only ensures they meet the optimal sleep quota but also enhances their overall health and cognitive function.

The benefits extend beyond the mere number of hours slept; the quality of sleep improves, fostering better mental, emotional, and physical health. This holistic improvement in well-being is crucial during adolescence, a period marked by significant growth and development challenges.

• Adequate sleep is crucial for teenagers’ physical and mental development, supporting growth, immune response, and emotional regulation.
• Recommended sleep leads to fewer behavioral issues and improved decision-making.
• Important during adolescence, a time of significant development.
• Sufficient sleep is linked to better mood regulation and reduced risk-taking.
• Schools can help teens get the necessary sleep, promoting academic success and well-being.
• Recognizes the link between physical health, mental health, and academic achievement.

Behavioral and social scientist Wendy Troxel explains how early school start times essentially cause daily jetlag for students and advocates for a change in their morning routines in a compelling video worth watching.

3. Reduces Absenteeism

Healthier students are more likely to attend school consistently, underscoring the impact of sleep on immune function and overall wellness. By adapting school schedules to allow for more sleep, educators can directly contribute to reducing absenteeism and enhancing the learning environment.

Later school start times contribute to a healthier student body, which directly impacts attendance rates. Sleep deprivation compromises the immune system, making students more susceptible to illness and, consequently, more likely to miss school. By ensuring that students get sufficient rest, schools can see a reduction in absenteeism.

This not only benefits students’ academic performance and continuity of learning but also contributes to a more vibrant, participatory school environment. Improved health outcomes due to adequate sleep thus serve as a preventive measure against common ailments, ensuring that students remain present and engaged in their educational journey.

• Regular attendance is essential for continuous learning and success.
• Each missed day is a lost opportunity for learning and interaction.
• Absenteeism creates knowledge gaps, affecting confidence and curriculum engagement.
• Reducing absenteeism with later start times ensures full participation in education.
• Improves academic outcomes, social integration, and school connectedness.
• Alleviates administrative and teaching challenges, leading to a more efficient educational process.

4. Lowers Risk of Depression and Mental Health Issues

The crucial relationship between sleep and mental health, particularly in adolescents, cannot be overstated. Addressing sleep deprivation through later school start times is a preventative measure that could significantly improve students’ mental health outcomes.

The interplay between sleep and mental health is critical, especially during the volatile adolescent years. Inadequate sleep has been consistently linked to increased risks of depression, anxiety, and other mental health issues. By shifting school start times later, students are afforded the opportunity to align their sleep schedules with their biological needs, significantly mitigating these risks.

This preventive approach to mental health is of paramount importance, considering the rising incidence of mental health challenges among teenagers. Providing an environment that supports adequate sleep can be a fundamental strategy in promoting mental well-being, offering a buffer against the stressors and challenges of adolescence.

• Mental health’s critical role in students’ well-being and success is undeniable, with adolescence being a particularly vulnerable period for the onset of issues like depression and anxiety. Sleep deprivation significantly exacerbates these conditions.
• Ensuring adequate sleep is foundational for robust mental health, enabling students to better manage stress and the myriad challenges of adolescence with greater resilience.
• Schools that implement later start times contribute to a proactive approach to mental health care, leading to a noticeable reduction in the incidence and severity of mental health issues among students.
• This initiative fosters a supportive educational environment where every aspect of student well-being is nurtured, promoting a healthy school climate conducive to learning and growth.

5. Reduces Drowsy Driving in Teens

With the initiation of driving coinciding with the teenage years, the risk of drowsy driving becomes a pressing concern. Adjusting school start times to ensure teenagers get enough sleep could be a critical step in enhancing road safety and reducing accidents.

Teenage years coincide with the commencement of driving for many, introducing risks associated with drowsy driving. The CDC has identified sleep deprivation as a key factor in teen driving accidents. By enabling teens to align their sleep schedules with natural rhythms through later school start times, the incidence of drowsy driving can be significantly reduced.

This has the dual benefit of enhancing individual safety and contributing to broader public safety outcomes. Preventing accidents through such measures not only saves lives but also fosters a culture of responsible driving habits among young individuals.

• The safety of teenage drivers is a paramount concern, with drowsy driving posing a significant risk not just to the drivers but to the community at large. The alertness of drivers is crucial and is directly influenced by the amount of sleep they have received.
• By pushing school start times later, we can mitigate the risk of accidents caused by sleep deprivation, significantly enhancing public safety and specifically safeguarding teenage drivers, who are often less experienced and more vulnerable on the road.
• This measure not only prioritizes the health and safety of students but also contributes to the broader goal of ensuring safer roads and communities.

6. Helps Teens Feel Happier

Sleep deprivation negatively impacts adolescents’ mood and overall happiness. Schools that adopt later start times can help align students’ schedules with their natural sleep patterns, fostering improved well-being and a more positive school experience.

Aligning school schedules with teenagers’ natural sleep cycles can significantly enhance their overall happiness and well-being. The dissonance between early school start times and adolescents’ biological predisposition for later sleep and wake patterns can lead to chronic sleep deprivation , affecting mood and well-being.

By adopting later start times, schools can help rectify this misalignment, allowing students to adhere to a more natural sleep schedule. This adjustment can lead to improved mood, greater resilience, and a more positive outlook on life, which are crucial for healthy adolescent development and academic success.

• The well-being and happiness of students are essential for their active engagement and enjoyment of their educational journey. Students who are well-rested show a marked increase in engagement, curiosity, and motivation.
• By aligning school start times with teens’ natural sleep cycles, there’s a significant improvement in students’ overall mood and outlook on life, which in turn enhances their social relationships and reduces conflict.
• This positive adjustment has been linked to not only a more vibrant school environment but also to tangible improvements in academic performance, demonstrating the deep interconnectedness between emotional well-being and educational outcomes.

7. Reduced Stress

The stress induced by early mornings and lack of sleep can significantly affect students’ academic and social lives. By moving the start of the school day later, schools can alleviate a major source of daily stress, contributing to a healthier, more conducive learning environment.

The impact of sleep on stress levels cannot be overstated. Starting school later can significantly reduce the morning rush, a source of daily stress for many students. This reduction in stress can have a domino effect on various aspects of students’ lives, including their academic performance, social interactions, and overall mental health.

By mitigating one of the many stressors in students’ lives, schools can create a more supportive and productive learning environment. The benefits of such a change extend beyond the individual, positively affecting the school culture and community at large.

• Stress stands as a formidable barrier to both learning and mental health, with its ability to impair cognitive function and negatively affect academic performance. The rush and pressure of early mornings contribute significantly to students’ stress levels.
• Adopting a later start to the school day offers students a schedule that is more in sync with their natural sleep patterns, effectively reducing morning stress and allowing for a calmer, more focused start to their academic activities.
• This reduction in stress is beneficial not only for students’ academic performance but also for their mental and physical health, contributing to a more positive, supportive, and productive educational environment.

The Potential Drawbacks of Starting School Later

1. scheduling sports and extracurriculars becomes more difficult.

The integration of later school start times presents a unique set of challenges for the scheduling of sports and extracurricular activities, which are vital components of a student’s holistic development. The shift could potentially disrupt the delicate balance between academic commitments and extracurricular engagement, affecting students’ ability to participate in these valuable experiences.

One potential drawback of starting school later is the complication it introduces to scheduling sports and extracurricular activities. Many students are actively involved in after-school programs, including sports teams, clubs, and other organizations that play a significant role in their development. This presents a clear argument for why school should not start later, as it could lead to conflicts with extracurricular activities that depend on fixed schedules. This can result in logistical challenges for both students and program coordinators, potentially causing students to miss out on opportunities that contribute to their growth beyond academics.

In response to this challenge, schools and communities can adapt by rethinking and possibly reinventing the scheduling and structure of extracurricular activities. Flexibility in planning, such as holding some activities in the morning or making more efficient use of weekends, can ensure students continue to benefit from these programs. Moreover, a later start time might actually enhance student participation and performance in extracurriculars, as students would be better rested and more focused, potentially leading to a richer extracurricular experience.

2. Increases Childcare Costs and Logistical Challenges for Working Parents

Transitioning to later school start times poses significant logistical and financial challenges for working parents, necessitating adjustments in childcare arrangements and potentially disrupting daily routines. This change can introduce added stress and financial burden on families, complicating the work-life balance that is crucial for the well-being of both parents and students.

The shift to later school start times can increase childcare costs and create logistical challenges for working parents. Parents may find themselves needing to arrange for additional morning care or adjust their work schedules to accommodate the change. This can add financial strain and complicate the balance between work and family life, creating stress and potentially impacting the overall well-being of families.

However, the community and employers can play a crucial role in easing this transition. Workplaces could offer more flexible working hours or remote work options to accommodate the needs of parents. Additionally, schools and community organizations might develop affordable before-school programs to support families. This approach not only addresses the logistical and financial concerns but also fosters a community-centric solution that benefits both students and their families.

3. May Make After-School Jobs and Activities More Difficult

Adjusting school hours to start later in the day could inadvertently impact students’ ability to engage in after-school jobs and activities, critical for their personal development and financial support. This shift may limit the time available for such commitments, posing challenges for students who depend on the afternoon and early evening hours for work and extracurricular participation.

For students who rely on after-school jobs for income or participate in non-school activities, a later dismissal time can significantly reduce the available hours for work and other commitments. This could affect their ability to support themselves or their families financially and limit their engagement in valuable community or personal development activities.

On the flip side, a later start time can lead to more alert and productive students, potentially making them more efficient in balancing work, activities, and school responsibilities. Schools and local businesses could collaborate to offer flexible working arrangements for students, recognizing the mutual benefits of supporting adolescent development while maintaining their contribution to the workforce and community engagement.

4. Reduces Time for Homework and Family Activities

A later dismissal time from school may compress the window available for homework, relaxation, and family time, essential components of a student’s well-being and academic success. This reduction in available time during the evening can increase stress and limit opportunities for meaningful family interaction and adequate academic preparation.

With a later end to the school day, students might find themselves with less time for homework, relaxation, and family activities in the evening. This compression of non-school hours could lead to increased stress, less downtime, and diminished family interaction, which are all important for a student’s well-being and academic success. Uncover persuasive reasons against adopting year-round schooling in “ Comprehensive Analysis: 8 Strong Reasons Why School Should Not Be Year-Round ” highlighting its possible effects on both students and educators.

This challenge necessitates a more efficient approach to homework and after-school time management, potentially encouraging schools to reassess the volume and nature of homework assigned. With strategic planning and support, students can learn to manage their time effectively, ensuring they have sufficient opportunities for both academic responsibilities and family engagement. Additionally, the quality of family time can improve when students are less stressed and more rested, making the time spent together more meaningful.

The Impact of Delayed School Start Times in Seattle School District

In the 2016-2017 academic year, the Seattle School District embarked on a pioneering initiative to address the chronic sleep deprivation affecting its secondary school students. Recognizing the mounting evidence on the importance of adequate sleep for adolescents’ physical, and mental health, and academic performance, the district made a decisive move to delay the start times of its secondary schools from 7:50 am to 8:45 am. This change was aimed at aligning school schedules more closely with students’ biological sleep needs, thereby enhancing their overall well-being and academic outcomes.

Researchers from the University of Washington seized this opportunity to conduct a comprehensive study, both before and after the implementation of the new start times. Their research included students from two public high schools in Seattle, providing a valuable case study on the impacts of such policy changes.

The findings, published in Science Advances, revealed significant benefits stemming from the later start times. On average, students gained an additional 34 minutes of sleep per night, increasing their total nightly sleep from six hours and 50 minutes to seven hours and 24 minutes. This increase brought students closer to achieving the recommended sleep amount and marked a reversal in the century-long trend of gradual sleep loss among adolescents.

The benefits of this policy change extended beyond just improved sleep duration:

• Improved Sleep Duration: The policy change led to longer sleep times for students.
• Enhanced Academic Performance: Observations showed a significant increase in students’ academic achievements.
• Increased Punctuality and Attendance: Notably higher rates of on-time arrivals and attendance, especially in economically disadvantaged schools.
• Narrowing Socioeconomic Learning Gap: The change suggests the potential to reduce disparities in educational outcomes between low and high socioeconomic groups.
• Reduced Daytime Sleepiness: Students experienced less sleepiness during the day, indicating better sleep quality and its positive effect on daily engagement and functioning.

Dr. Tara Narula reports on a Seattle school district that transitioned to a later start time, showcasing the positive outcomes of the study, making it a highly recommended video to watch for insights on the impact of such changes.

Despite the success observed in Seattle, such shifts in school start times remain relatively rare across the United States, where the typical start time still hovers around 8 a.m. However, the Seattle School District’s experience stands as a compelling testament to the benefits of later start times, supported by the American Academy of Pediatrics’ advocacy for this change as an effective countermeasure to the widespread issue of sleep deprivation among teenagers.

The Seattle School District’s initiative demonstrates a proactive approach to student health and education, providing valuable insights and evidence for other districts contemplating similar adjustments. By prioritizing the sleep needs of students, the district not only improved their academic and health outcomes but also set a precedent for the importance of aligning educational policies with scientific research on adolescent well-being.

Persuasive Essay About Why School Should Start Later

Table of contents:

• Introduction
• Body paragraphs

It’s one of the favoured topics among high school students. You’re tired. After being up late last night, your school day started at 8:30 am this morning, and you want to know if anything can be done about it. Or perhaps you’re an early bird and like the time that school starts in the morning. Well, you can write a persuasive essay, and maybe if it’s good enough, your voice will be heard, either way.

Start off by taking a firm stance with your thesis statement. Whether you feel school should start later in the morning, or should not, you need to figure out why, and the reasons and benefits (or negatives) in your own mind, first of all. Make a quick outline with your statement of purpose at the top, followed by each point you want to make and the evidence you are going to use to support each point. Remember that you can use any evidence you like in a persuasive essay; it need not be restricted to facts and figures, but can be anecdotal, emotive, or statistical. Think of yourself as a politician trying to persuade an audience to vote for him or her.

Introduction examples

Pro: It’s been proven in many studies that teenagers do better with a later start to the day. With this in mind, why do we still start school at 8:30 in the morning?

Con: Starting later in the day at school interferes with parents’ working days, encourages students to stay up late, and would cause problems with after-school practices for sports.

Moving on into the body of your essay, carry on following your outline, setting up each point and presenting your evidence as you go. Have a look at potential titles, too, which should be reflective of your thesis statement.

Body paragraphs examples

Pro: Teenagers in high school should start at about 10 am. This would allow for a leisurely morning, making the day start off less fraught and stressful. A teenager could stay up until midnight or 1 am and still get a decent amount of sleep, which doesn’t happen when they have to wake up at 6:30 or 7 am. Traffic, too, will be more spread out, easing congestion, and students can take the time to get a good breakfast and be really mentally prepared for the day.

Con: Parents worry about getting themselves to work on time even when school starts at 8:30. A lot of working days would have to change significantly for people to get to work on time if high school started at 10 am instead. This could lead to large amounts of business disruption, and possible discrimination against parents for needing more flexible working hours.

Your conclusion is your last chance to leave an impression on your audience, so make it significant and meaningful. Start by briefly reiterating what your points were, and finish with a bang by calling on your audience to take some action in response to your essay.

Conclusion examples

Pro: Starting later results in benefits for teachers, benefits for students, and also for parents. Think about how rested you’d feel if you had a full eight hours or more sleep each night, and how much more you could get done in your day.

Con: A later school start will throw Australian cities into chaos and maybe even cause some parents to face consequences at work. The way things are now is fine, and there’s no need to fix what isn’t broken.

Let’s learn about why schools should start later.

Most U.S. high schools start before 8:30 a.m. — too early, according to experts

When school times start later, teens tend to feel better and do better in school.

January 17, 2023 at 6:30 am

One of the hardest things about going back to school after a break is waking up for it. And unfortunately, many schools start too early, according to scientific experts.

The American Academy of Pediatrics says that middle and high schools shouldn’t start before 8:30 a.m. That’s because as people go through puberty, their internal clocks naturally shift . It becomes hard for them to nod off before 11:00 p.m. But teens still need an average of nine hours of sleep per night. So, when they have to get up before the sun peeks over the horizon, they miss out on crucial shut-eye.

Dozing in class is only the most visible of problems cause by this lack of sleep. That sleep now lost to early alarm clocks is vital for helping the body grow and heal from illness or injuries. The brain also loses out on time to process memories. Sleepy teens are more likely to feel anxious or depressed, as well as use drugs or alcohol. And sleeping in on weekends is no replacement for lost zzz’s during the week. Binge-sleeping poses its own health risks .

Some schools have shifted their start times to later in the morning. Researchers are now tracking the impacts. It seems that teens who start school later do get more sleep. They’re more likely to get to class on time and stay awake during the day. They even seem to do better in school .

21% of teen motor vehicle accidents are caused by drowsy driving. Drowsy, exhausted students are often complaining about their school start times being way too early. Because they have to wake up so early, it makes the school day very exhausting for them. Teen tiredness is now considered to be a public health pandemic. School starting at a later time is beneficial because it helps students catch up on sleep, it helps students stay out of trouble, and it helps students’ ability to learn. (5)

One reason school times should start later is because it will help students catch up on sleep. “Sleep deprivation has become virtually epidemic among American teenagers. Research suggests that adolescents require about 8.5 to 9 hours of sleep, but according to the National Sleep Foundation, only 14% achieve this goal” (Peorgers 4). To not get the recommended amount of sleep causes a repercussion on the human body and brain. Lack of sleep increases students chances of depression and suicidal thoughts. It can also potentially weaken the immune system. The school day is hard enough on a child and not getting enough sleep does not make it any better. School starting later will benefit many teens on getting the rest they need in order to take on the challenging school day. There are 15% of schools in America that start after 8:30. Because those schools pushed back start times, it improved their students energy at school. Even pushing back the start time by just 30 minutes has helped a lot in students behavior. (9)

Another reason why school should start later is, it will help students stay out of trouble. “Later school days mean less unsupervised time for teenagers, meaning that bored youth would less likely to get in trouble” (Late 1). In some places, schools get out as early as 2:30. To get out that early leaves students with a lot of time on their hand. If school were to start at a later time, it would mean that it would end at a later time. This could potentially help students stay out of trouble. To decrease the number of hours students have after school, it will help them stay occupied with their education. (7)

“Grades would improve, it is argued, because teenagers seem wired to sleep in later and so would arrive at school less tired and more willing to learn” (Late 1). If students obtain the correct amount of sleep it is known to increase their ability to learn. Students will show up to school with a more optimistic outlook on their education. To not get enough sleep, students show up to school very irritable and in a bad mood. When irritable, it causes students to lash out at people who do not deserve it. And when everyone is irritable, school then becomes a negative place for students due to everyone’s grouchy attitude. In the classroom, teachers struggle to teach their students when all they see is eyes that are half open or eyes that are not open at all. (7)

Although there are many excellent and logical reasons as to why schools should start at a later time, there are also many logical reasons as to why it should not. “If students were to be pampered by a late school start, we would get a rather big shock when, further down the track, our employers would expect us to begin work at 8am” (Leave 7). For school to start later, it would mean the students with after school jobs cannot put in as many hours as they would be able to if the school ours were left alone. Students are also involved in sports that require after school practices. School getting out later means that practices will run later too. Because the practices would run late it would leave students less time to complete homework, not to mention the students who live out of town and have a long drive to get home. (5)

Students would greatly appreciate getting extra sleep even if it has it’s disadvantages. If all schools delay the school start times it will help students catch up on sleep. It will help students stay out of trouble. And last but not least it will help students and their ability to learn. For students to get the required amount of sleep it will decrease the number of motor vehicle accidents. All in all, delaying the school start time has proven to improve students’ school day. (6)

10 Reasons Why School Should Start Later (Top Benefits!)

Research demonstrates that school starting later is good for adolescents . It can give them more time to sleep and even improve test scores.

Nevertheless, school starting later does have some downsides. Parents need to get their children off to school early so they can go to work and earn money for their families.

Here are my top 10 reasons why school should start later.

• Helps students focus
• Caters to their natural sleep timetable
• Reduce the risk of car accidents
• Reduces risky behavior
• Improves information retention
• Helps teens feel happier
• Improves attendance
• Reduces stress
• Increases breakfast consumption
• Caters to their needs

There are a number of reasons school should start later, and it’s not just because the teenagers are being lazy and want to sleep in. The rest of this article will address the scientific reasons defending a later start for schools.

Don’t miss the other side of the debate: Reasons School Should Start Earlier!

Reasons Why School should Start Later

1. school helps students focus.

One of the primary reasons school should start later is that it helps them focus. For students who are naturally inclined to stay up late and sleep in, going to school earlier can disrupt their circadian rhythm, diminishing their capacity to retain information.

What teachers often mistake for laziness is often the student’s body being negatively impacted by an unnatural biological cycle, compounding in a lack of focus on schoolwork.

In fact, a study by Lufi et al. (2011) found that an extra hour of sleep for adolescents significantly increased their attention levels on the “Mathematics Continuous Performance Test”.

By contrast, students that have a hard time focusing are also often singled out for misbehavior, which can affect their self-perception and make them less inclined to put in effort at school.

2. Caters to Their Natural Sleep Schedule

Another important reasons why school should start later is that a later start is better for students’ natural sleep cycle.

Especially for teenagers, the tendency is to stay up late and sleep longer, needing 8.5-9.5 hours to be fully rested. For a student who goes to bed at 11p.m., they would need to sleep until 7:30-8:30a.m. to be fully rested, a time frame when most schools have already started.

At the end of the day, better sleep means better performance in school. Students who feel refreshed in the morning are more likely to be optimistic about the day’s work and more receptive to learning.

3. Reduces the Risk of Car Accidents

Aside from improving student learning, a longer rest period for students who drive reduces the risk of car accidents.

For teens who are just learning how to drive, adding on an early school start is just a recipe for disaster. Teenagers make up over 50% of all car accidents that involve fatalities, and it certainly makes one wonder just how many of them are caused by sleep deprivation.

Lack of sleep slows down motor reflexes (Taheri & Arabameri, 2012) and makes a driver far more likely to make an error in judgement and cause an accident. Paired with their biological need to sleep longer, teens who start school earlier are more likely to get into accidents in the morning.

4. Reduces Other Risky Behaviors

Sleep-deprived teenagers are more likely to engage in any risky behaviors, not just driving dangerously.

While, of course, there are other factors that contribute to adolescent risk-taking (not least of which is an underdeveloped brain ), there’s no denying that sleep-deprived students aren’t using their mental faculties to full effect when it comes to risky decision making.

Switching to a later start time can help students, especially teenagers, feel more rested, emotionally stable, and less sleep-deprived so that they maximize their chances of making intelligent decisions.

5. Improves Information Retention

As well as helping students focus in the classroom environment, a later school start helps students retain information during class, especially those first and second period classes getting into the swing of the day.

Retaining information requires a lot of brainpower, something that students might struggle to conjure up if they are sleep-deprived.

A later start gives students more time to prepare themselves mentally for the day of learning ahead, helping them retain more information along the way.

One of the most extensive systematic reviews of the literature on school start times found that mid- to long-term memory retention is mildly improved with increased sleep in adolescents (Marx et al., 2017).

6. Helps Teens Feel Happier

When school starts early, teenagers can feel as though their natural circadian rhythm is off all the time, negatively affecting their mood and sense of well-being.

In fact, well-being is one of the most positive outcomes from research on late school start times (Marx et al., 2017).

Anecdotally, teenagers seem to be inclined to go to bed later (perhaps due to less self-governing abilities than adults). They also tend to need longer periods of rest than adults because they are going through significant physical and cognitive changes.

With that in mind, a later start to school is more in line with their biological needs and can positively affect their happiness.

7. Improved Attendance (Potentially)

Students who struggle in school or don’t see the merit in education often have a hard time motivating themselves to work hard, or even attend school at all.

When classes begin before 8:00, which is common in most schools, students on the periphery may feel more inclined to skip first period altogether to catch up on their sleep.

Starting a little later removes that concern and helps students who are struggling to motivate themselves take a little more time in the morning to prepare for the day ahead.

8. Reduced Stress

In a similar vein, students face a lot of stress that can negatively affect their performance in school, and the prospect of starting school so early is yet another factor that may contribute to stress in their lives.

Starting school later may on a case-by-case basis reduce stress, especially when it comes to attending first period. For example, the systematic review by Marx et al. (2017) found that some research shows that children often “are less tense at home, and school nurses have reported fewer stress-related complaints and illnesses.”

9. They Eat More Breakfast

A later school starting time may mean students will consume more breakfast.

Marx et al’s (2017, p. 13) systematic review found that some evidence points toward this outcome:

“There has been some indication (especially in Wahlstrom 2002) that students in later starting schools eat breakfast more often.”

Of course, intuitively this makes sense. They will have more time in the morning to prepare for school, meaning there is extra space in the day to allow young people to prepare and eat their breakfast.

The benefits of eating breakfast are vast – including heart health, better memory retention, and more stable moods.

10. Caters to Their Needs

Lastly, and in summation, starting school later than 8:00 helps cater to what the students want and need.

Most students would prefer not to have to run through the routine of preparing for school early in the morning if they could start later, and for teenagers especially, starting later could be a way to address their wants and needs .

There are a number of reasons school should start later than it does, and most students would jump at the chance to shift their first period back by just an hour. Starting school later helps students get a better night’s sleep, focus on their classwork, and improves their chances of success.

How to Write a Thesis Statement | 4 Steps & Examples

Published on January 11, 2019 by Shona McCombes . Revised on August 15, 2023 by Eoghan Ryan.

A thesis statement is a sentence that sums up the central point of your paper or essay . It usually comes near the end of your introduction .

Your thesis will look a bit different depending on the type of essay you’re writing. But the thesis statement should always clearly state the main idea you want to get across. Everything else in your essay should relate back to this idea.

You can write your thesis statement by following four simple steps:

• Start with a question
• Write your initial answer
• Develop your answer
• Refine your thesis statement

A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.

The best thesis statements are:

• Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
• Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
• Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

Prevent plagiarism. Run a free check.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .

The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts and among young people more generally is hotly debated. For many who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.

You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.

You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?

For example, you might ask:

After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.

In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.

The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.

In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.

The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.

A strong thesis statement should tell the reader:

• Why you hold this position
• What they’ll learn from your essay
• The key points of your argument or narrative

The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.

These examples are more specific and show that you’ll explore your topic in depth.

Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:

• In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
• In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

The thesis statement is essential in any academic essay or research paper for two main reasons:

• It gives your writing direction and focus.
• It gives the reader a concise summary of your main point.

Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.

• Ask a question about your topic .
• Write your initial answer.
• Develop your answer by including reasons.
• Refine your answer, adding more detail and nuance.

The thesis statement should be placed at the end of your essay introduction .

Insufficient sleep in adolescents has been shown to be associated with a wide variety of adverse outcomes, from poor mental and physical health to behavioral problems and lower academic grades. However, most high school students do not get sufficient sleep. Delaying school start times for adolescents has been proposed as a policy change to address insufficient sleep in this population and potentially to improve students’ academic performance, reduce engagement in risk behaviors, and improve health.

This paper reviews 38 reports examining the association between school start times, sleep, and other outcomes among adolescent students.

Most studies reviewed provide evidence that delaying school start time increases weeknight sleep duration among adolescents, primarily by delaying rise times. Most of the studies saw a significant increase in sleep duration even with relatively small delays in start times of half an hour or so. Later start times also generally correspond to improved attendance, less tardiness, less falling asleep in class, better grades, and fewer motor vehicle crashes.

CONCLUSIONS

Although additional research is necessary, research results that are already available should be disseminated to stakeholders to enable the development of evidence-based school policies.

Sleepy adolescents have doubtlessly been a problem for a long time. However, it is only since the late 1980s that this issue has progressed from teachers’ anecdotes of students falling asleep in class and parental complaints of daily struggles to get their children out of bed to scientific investigations into the causes and consequences of insufficient sleep.

Most adolescents may need at least 9 hours sleep per night 1 – 3 ; however, fewer than 8% of high school students report getting this amount. 4 Less than a third of students report 8 or more hours of sleep, and this proportion decreases as school grade level increases so that fewer than a quarter of high school seniors get this amount. 4 Healthy People 2020, a national initiative designed to guide disease prevention and health promotion efforts to improve the health of all Americans ( http://www.healthypeople.gov/ ), contains 4 objectives related to sleep, including one for adolescents. 5 This objective is to “increase the proportion of students in grades 9 through 12 who get sufficient sleep (defined as 8 or more hours of sleep on an average school night).”

Insufficient sleep in children and adolescents has been shown to be associated with a wide variety of adverse outcomes in multiple aspects of their lives from poor mental and physical health to behavioral problems and poor academic grades. Insufficient sleep has been linked to excess weight, 6 – 13 decreased physical activity, 14 and increased food intake, possibly due to alterations in appetite-regulating hormones. 12 Results of investigations into longitudinal changes in weight attributable to sleep duration, however, have been mixed. 10 , 15

A solid body of literature has found that insufficient sleep in this young population is tied to poor mental health, including depression, depressive symptoms, 8 , 16 – 22 and suicidal ideation. 8 , 18 , 20 , 22 – 25 In addition, a few studies have shown an association between insufficient sleep and unhealthy risk behaviors including alcohol use, 17 , 19 , 20 , 22 tobacco smoking, 20 , 22 marijuana use, 20 , 22 use of other illicit/prescription drugs, 22 unhealthy weight control strategies, 26 and recent sexual activity. 20 Other factors that have been found to be associated with insufficient sleep include risk-taking behaviors, 27 bullying, 28 school violence-related behaviors, 29 and physical fighting. 20 Short sleep duration has also been found to be associated with a higher risk of unintentional injury. 30 Finally, students who do not get enough sleep also may be more likely to have problems paying attention and poor academic performance, 17 , 21 , 31 – 36 although not all research agrees. 37 , 38 One of these negative studies failed to find a correlation between school night sleep duration and grade point average. 37 However, class grading and subsequently grade point averages are not standardized and may vary by subject, teacher, and school. That study also did not adjust by sex of student, which was a strong predictor of grade point average. Ming et al. found that “students with a sleep length of less than 7 hours on both weekdays and weekends exhibited poorer performance, while those who made up this sleep loss on weekends did not.” 38 That study also relied on a non-standardized measure of academic performance and did not adjust for variables such as grade in school, which is strongly related to prevalence of insufficient sleep.

Adolescents tend to get insufficient sleep because of a combination of late bedtimes and early rise times. External factors that contribute to later bedtimes among adolescents include an increase in schoolwork; participation in afterschool activities, including employment; fewer parent-set bedtimes; and late-night use of technology in the bedroom. 39 – 43 Biology also plays a part in later bedtimes among adolescents. One of the early changes associated with puberty is alteration of a child’s circadian rhythms, such that adolescents are more alert in the afternoons and evenings and require morning sleep. 44 Their natural body clocks can keep adolescents awake until 11 PM or later, in spite of going to bed earlier and good sleep hygiene, such as avoiding stimulating activity at night and minimizing caffeine intake in the afternoon or evening. 39 School-based sleep promotion programs have been tried as a means of improving sleep hygiene among adolescents. However, these programs may improve knowledge of sleep without having a significant effect on behavior. 45 , 46

Rise times, on the other hand, are primarily determined by a single factor—school start times. 43 Delaying school start times for adolescents has been proposed as a policy change to address insufficient sleep in this population and potentially to improve students’ academic performance, reduce engagement in risk behaviors, and improve health. In 2014, the American Academy of Pediatrics published a policy statement urging middle and high schools to adjust start times to permit students to obtain adequate sleep and improve physical and mental health, safety, academic performance, and quality of life. 3 This paper reviews studies examining the association between school start times, sleep, and other outcomes including academic performance, mental health, and motor vehicle collisions among adolescent students. This paper, and especially the table provided, is intended to be a resource for educators, parents, and other stakeholders who wish to learn more about the impact of changing school start times for adolescents.

LITERATURE REVIEW

An outline of the steps in identification of articles and reports included in the literature review is presented in the Figure . To be included in the review, analyses had to include the variable of “school start time” either by comparing different schools with different start times (cross-sectional) or the same schools before and after changes in start times (longitudinal). Since the focus of this review is on the effect of school start times on adolescent students, studies that focused on elementary school (pre-middle school) students were excluded. Additionally, reports had to be available in English, but could include schools either in or outside the United States. Articles for the literature review were initially identified through a PubMed search for “school start time” OR “school start times” (Step A). Some exclusions from this initial search included a study that compared students in public or private schools to homeschooled students, 47 a comparison of adolescent sleep during summer and during the school year, 48 and one that modeled the effect of modifying school start times on the frequency of encounters between child pedestrians and motor vehicles. 49 Another broader PubMed search for “sleep” AND “adolescent” AND “school” resulted in approximately 3200 articles (Step B). Titles and abstracts were reviewed to identify studies that might meet primary inclusion criteria. Full-text review of candidate articles confirmed inclusion of articles for this review. Reference lists of articles identified in Steps A and B and reviews of the topic of school start times were reviewed for identification of additional reports (Step C). Several of the earliest studies with results presented in abstract form only were identified in this manner, 50 – 54 as were some studies from the education or economics literature that were not indexed by PubMed. 55 – 59 A Scopus search for “school start time” (all fields) found 320 documents (Step D), of which 3 satisfied the inclusion criteria and had not been identified in previous steps. Finally (Step E), one additional non-duplicative report was identified in the reference list for articles in Step D. Final searches in Steps A, B, and D were conducted July 1, 2015. For this review, 38 reports were reviewed for years of study, study design, sample size, students’ ages, location, school start times, outcomes, and key reported findings. Five of these reports are listed more than once in the table. Three reports included multiple study populations whose data are analyzed separately. 59 – 61 Three reports included cross-sectional and longitudinal components, with data for each component presented separately. 55 , 57 , 61

Identification of Reports for Review

The primary limitation to this review is its reliance on indexing by PubMed and Scopus, which could lead to omission of reports not indexed by these databases. To address this limitation, we also examined the reference lists on previous articles on the topic of school start times (Steps C and E). Five of the 38 reports were identified in this manner. Publication bias and over-representation of studies with significant results is also possible, however, some studies included in this review had results that did not agree with the majority.

Types of School Start Time Studies

We reviewed 38 reports on the impact of changes in school start time (see Table ). Unfortunately, the earliest reports, 50 – 54 which have been cited frequently, were only published in abstract form. However, since they seem to have provided the impetus for much of the subsequent research and are fairly detailed, we have included them in this review. The studies presented in this review can be categorized as either cross-sectional or longitudinal. The cross-sectional studies simply compared characteristics for students at two or more schools having different start times, such that School A had an earlier start time than School B and compared how students at the two schools with respect to such outcomes as sleep duration, school attendance, academic performance, and morning traffic accidents among teens.

Descriptions of School Start Time (SST) Studies in Preadolescents, Adolescents, and College-Age Students

Abbreviations: ACT, originally American College Testing – one of two standardized tests commonly used in college admissions in the United States; HS, high school; MS, middle school; NR, not reported; SD, standard deviation; SST, school start time.

Changing school start times is often a major endeavor that involves coordination between school faculty and staff, transportation resources, parents, students, and administration, and can take years to accomplish. Cross-sectional studies can be conducted without having to wait for a school or school district to undertake a change in school start time. However, as with all cross- sectional studies, only associations between school start times and other variables can be shown—not cause and effect. Other school characteristics, such as socioeconomic status of students, can also have effects on sleep and other outcomes but is often not reported.

In the longitudinal studies, data are collected on students and schools before and after a change in start time. Some data that are regularly collected by schools, such as attendance and grades, can be obtained retroactively by researchers. Other data, such as those obtained from student sleep surveys, need to be collected before the start time change is implemented, and including these data can increase the duration of the study. Some studies evaluate characteristics of the same students before and after the change. Others evaluate the student population (either the entire school or specific grades in school) before and after the change. This second method, for instance, could compare outcomes in 9th-grade students in the year before the start time change with the same outcomes in 9th-grade students in the year after the change. Both of these methods have their drawbacks. Although it would seem to be preferable to evaluate the same students before and after a change, individual students can undergo significant changes from year to year that could exaggerate or diminish the effect of changing start times. However, by being able to evaluate changes in variables for individual students, researchers are able to address questions such as, “Did the students who got more sleep after the start time’s change have improved outcomes?” Although longitudinal studies may provide stronger evidence of causation than cross-sectional studies by addressing the issue of temporality, it is important to assess whether appropriate control conditions are used, whether analyses account for covariates (eg, age, sex, or socioeconomic status), and whether other explanatory variables are considered (eg, implementation of graduated drivers licensing).

Sleep and Sleepiness

Since delaying school start times is primarily intended to address the problem of insufficient sleep among adolescents, most of the studies focused on the association between school start times and sleep variables. Not surprisingly, students at schools with later start times got out of bed later on school days than those at earlier starting schools. 35 , 36 , 50 , 53 , 55 , 56 , 60 , 62 – 69 The association between school start times and bedtimes, however, was mixed. Of 19 studies that evaluated the association between school start times and bedtime, there were no start time-associated differences in weekday bedtimes in eleven studies. 35 , 50 , 53 – 55 , 60 , 62 , 67 , 68 , 70 However, six studies observed a later bedtime among students in schools that started at later times. 34 , 36 , 56 , 64 , 66 , 71 It should be noted that in the study by Wolfson and colleagues, this bedtime difference was observed only in the autumn. 64 Two studies unexpectedly reported earlier bedtimes after a delay in start times. 65 , 69 In the study by Owens et al., some students stated that after seeing the benefits of getting more sleep with the delay in school start times, they sought to further increase their sleep by going to bed earlier. 65 In Paksarian et al, bedtimes were delayed by only 10 minutes for each 30 minute delay in school start times. 71 In 29 reports, a later start time was found to be associated with longer weekday sleep duration, 34 , 36 , 38 , 51 – 56 , 60 – 79 including the studies that noted later bedtimes. 34 , 36 , 56 , 64 , 66 , 71 In contrast to the majority of studies that observed longer sleep duration in later starting schools, two studies comparing students from schools with different start times did not observe a significant difference in sleep duration. 35 , 50 For one of these, the difference in sleep duration did not meet the authors’ effect size criterion, although the difference would not have been expected to be large since the difference in school start times was only 20 minutes. 35 The other study observed longer sleep duration for students at the later starting school, but the difference was not statistically significant. 50 Another study observed a significantly longer sleep duration for 7th- and 8th-grade students of only one of two later-starting districts. 60 Sleep duration for the second later-starting district was also longer than for the early-starting district, but the difference was not statistically significant. 60 Paksarian et al. observed longer sleep durations with later school start times (11 minutes for each 30 minute delay in school start times), but only for schools that started before 8:01 AM. 71 In further analysis, the authors found the longer sleep duration for boys only (20 minutes for each 30 minute delay in school start times) and that there was variation by urbanicity, with an increase in sleep duration for boys in major metropolitan areas and a decrease for boys in nonurban counties. 71 The authors suggested that the different association according to urbanicity may be due to differences in mode of transportation to school and time spent traveling to school, but they did not have data to investigate the possible role of transportation in their study. Although nearly all the studies reviewed used self-reported sleep data either from sleep diaries or survey questions, the two studies that used data from electronic wrist monitors (actigraphs) worn during sleep confirmed the general finding of longer weeknight sleep duration for students with later start times. 62 , 70 Eleven of the positive studies found that students got at least one additional minute of sleep for every two minutes of difference in start time (eg, at least 30 minutes more sleep when start time was one hour later), 34 , 55 , 56 , 60 , 61 , 64 , 65 , 68 , 70 , 72 , 78 although six other studies observed smaller, yet statistically significant, differences. 51 , 52 , 62 , 63 , 73 , 74

In addition to reporting longer sleep durations, students with later start times were less likely to report daytime sleepiness or falling asleep in class in nearly all studies that assessed these outcomes. 34 , 36 , 55 , 56 , 60 , 64 , 65 , 69 , 72 , 74 Two studies observed no difference in sleepiness based on school start times. In the Norwegian study, 78 start times were delayed from 8:30 AM to 9:30 AM on Mondays only. The lack of association could have been due to either the change being in effect only one day a week or the earlier start time already being late enough. In the Croatian study, 80 the students at the earlier starting schools were predominantly boys, while girls made up most of the population at the later starting schools. That study found that girls had later chronotype (evening preference) and more sleepiness. In addition, the schools in the Croatian study alternated their schedule weekly, with schools starting in the morning one week and in the afternoon the next. Even with a delay in start time, falling asleep during class appears to remain a major problem, however. In Wahlstrom and colleagues’ survey of students post-start time change, 27% reported falling asleep in a morning class in the previous 2 weeks, and 29% fell asleep in an afternoon class. 61

Other methods for assessing students’ degree of sleep-deficiency were used in various studies. Students in a study by Carskadon and colleagues underwent polysomnography (a type of sleep study that measures multiple factors such as electrical activity in the brain, heart rate, movements of the eyelids and legs, and respiratory airflow) and multiple sleep latency tests. 62 After an advance in start time from 8:25 AM to 7:20 AM, students had a shorter REM sleep latency (time between sleep onset and onset of REM sleep) on polysomnography and a shorter sleep latency (time to sleep onset during a standard testing protocol). 62 Both of these results indicate sleep-deficiency. Differences in sleep patterns between weeknights and weekend nights can also indicate insufficient weeknight sleep as students try to make up for lost sleep on the weekends. Seven reports that evaluated weekend sleep patterns found more “catch-up” sleep on the weekends for earlier start times, 51 , 61 , 64 , 66 , 69 , 74 , 78 although one found no difference in this outcome. 71 One study assessed weeknight and weekend sleep and observed longer weeknight sleep duration and no change in weekend sleep patterns after a delay in school start time, which could be interpreted as a decrease in “catch-up” sleep. 67 However, the difference between weeknight and weekend sleep was not analyzed. Three studies that included information about daytime naps noted that students with earlier school start times reported more napping, 38 , 66 , 75 presumably in an attempt to make up for insufficient nighttime sleep. Sleepy adolescents may also attempt to lessen sleepiness with caffeine. One study asked students about caffeine consumption and observed that caffeine use decreased after a 25 minute delay in school start time. 67

Academics and Cognition

An outcome of particular interest to school administrators, teachers, and parents is academic performance; however, evaluating how delayed start times affect school grades or academic performance is difficult for several reasons. Class grading is not standardized and varies by subject, teacher, and school. Standardized tests such as the Scholastic Aptitude Test or the ACT are not taken by all students and are more likely to be taken by students planning to attend college. Finally, students with very good academic performance before a delay in school start time do not have much room for improvement. Given these limitations, however, some evidence suggests a positive association between later school start time and academic performance, 57 , 58 , 60 , 61 , 64 , 81 although the association may be relatively weak 55 and not universal. 59 , 67 , 80

The first cross-sectional school start time study by the University of Minnesota found higher self-reported grades for students in later starting schools. 60 Mean self-reported grades for the two districts that started before 7:30 AM were 6.4 and 6.5 (on a scale from 1 = mostly F’s to 9 = mostly A’s) compared to 7.1 for the district starting at 8:30 AM (p < .05). However, the increase in grades observed from this group’s subsequent longitudinal study was small and not statistically significant. 55 In their latest longitudinal study including 8 schools, the same group noted that most schools saw an increase in grade point average after delaying school start times. 61 Arlington Public Schools (Arlington County, Virginia) observed an improvement in 10 th grade students’ 1 st period grades after a 45 minute delay in high school start times, with no change in 7 th grade students’ 1 st period grades after a 20 minute advance in middle school start times. 81 Hinrichs’ investigation into ACT scores and school start times in the Minneapolis-St. Paul area, which included school districts that did not delay school start times, controlled for various covariates and found no association between school start times and ACT scores. 59 The annual ACT participation rate among Minnesota high school graduates varied from 59% to 66% during the study period (1993–2002). 59 Hinrichs also evaluated the association between school start times and standardized test scores in Kansas (Kansas State Assessments) and the Virginia suburbs of Washington DC. 59 Again, he found no association between school start times and academic achievement in these analyses. 59 Wolfson and colleagues observed higher grades after delaying school start times for 8th grade, although not for 7th-grade students. 64 Another study linked school start times and standardized test scores for middle school students (grades 6–8) from 1999 to 2006 in the eighteenth largest public school district in the United States. 57 In the cross-sectional component of that study, an hour later start time corresponded to higher test scores on both math and reading (on the order of 3 percentile points). 57 The longitudinal component of the same report looked at schools that had changed school start times over the course of the study and found that a one hour delay in start time corresponded to a 2 percentile increase in math and 1.5 percentile increase in reading. 57 Among older students, U.S. Air Force Academy freshmen, students assigned to a first period course and therefore an earlier start to the school day had poorer grades. 58 A longitudinal study of nearly 200 boarding school students did not see a change in self-reported grades after a 25 minute delay in school start times. 67 In Milic et al.’s study in Croatia, students with an earlier school start time performed better academically than students at the schools with later start times. 80 However, in addition to the difference in the make-up of the student populations (more boys at earlier schools and more girls at later schools) in that study, students were also aware of the school schedule at enrollment and the response rate was low.

Several studies have investigated the association between school start time and cognitive outcomes. Two studies found that students with later start times reported fewer problems concentrating and paying attention. 70 , 72 In contrast, a study in Spain measured attention level via a sustained attention task among students at three schools with different start times (8:00, 8:15, and 8:30) and observed the highest average attention level at the school starting at 8:15. 77 However, it should be noted that the mean inductive reasoning score, a measure of intelligence which is positively associated with attention, was significantly lower for the latest-starting school than the other two schools. 77 The Norwegian study that delayed start times on Mondays included reaction time tests and found that students at the school with delayed start time had significantly fewer lapses and faster reaction times on Monday than Friday compared to no difference among students at the control (no delay) school. 78

Several studies asked students how much time they spent on homework. There was no consistent association between school start time and homework time. Wahlstrom and colleagues found that students with later school start times reported less hours of homework, 60 whereas Edwards observed the reverse 57 and Boergers and colleagues saw no difference. 67 Interpretation of these results in difficult. An increase in time doing homework could indicate an improved ability to concentrate or less efficient studying. Since the value of homework is hotly debated, this outcome should not be taken out of context.

Attendance/Tardiness

School attendance is also important for academic success. A recent report found that short sleep duration was strongly associated with odds of school absences. 82 Several studies included in this review found that earlier start times were also related to more frequent tardiness and more absences. 55 , 57 , 60 , 61 , 64 , 65 In one study, even with delaying start times from 8:00 AM to 8:55 AM, nearly a third of students reported being late to class because of oversleeping in the 2 weeks before the survey. 61 However, one study of schools in the Minneapolis-St. Paul area found no association between school start times and overall attendance rates. 59 The report by Arlington Public Schools stated that “maturity, rather than starting time, has the biggest impact on attendance rates.” 81 However, when comparing 10 th graders before and after the delay in high school start times, attendance rates were lower after the delay. Despite this finding, academic performance improved for those students. The report also noted that the attendance reporting procedures changed during the course of the study.

Sleep is strongly linked with many psychiatric disorders, including depression and anxiety. 83 Although sleep problems may be symptoms of mental health disorders such as depression, there is also evidence of a causal relationship between insufficient sleep and depression, as well as mood in general. 84 , 85 Due to this observation, some school start time studies included depression symptoms as part of their student assessments. Students at later-starting schools appeared to experience fewer depression symptoms (lower depression scores). 55 , 60 , 65 , 67 Incidentally, shorter REM sleep latency, such as was observed by Carskadon and colleagues after an advance in start time, 62 is also often observed in major depression. 86 One study found no difference in students’ positive or negative affect with delayed school start time. 78 However, in that study, the start time was delayed on Mondays only.

Motor Vehicle Crashes

Four studies also investigated motor vehicle crashes among young drivers (aged 18 years or younger) in areas served by schools with different start times. In a Kentucky county, Danner and Phillips saw a 16.5% decrease (p < .01) in motor vehicle crash rates for 17- and 18-year-old students in the 2 years following a 1-hour delay in school start time by county high schools. 74 During the same time period, crash rates for this age group increased by 7.8% in the rest of the state. 74 In their 2011 report, Vorona and colleagues compared crash rates for teen drivers aged 16 to 18 years in 2 neighboring, demographically similar cities (in eastern Virginia) with different start times. In 2007 and 2008, the teen crash rates were significantly higher in the city with an earlier school start time. 87 For both cities, teen crashes peaked during the morning commute time. 87 The group went on to perform similar analyses for two adjacent counties in central Virginia with different school start times. 88 During the 2009–2010 school year, crash rates among 16–18 year olds were higher (p < .05) in the county with the earlier school start times. 88 The following year, crash rates among 16–17 year olds were higher (p < .05) in the same county, but difference was not statistically significant when 18 year olds were included in comparison (p = 0.09). 88 Finally, Wahlstrom and colleagues investigated crash rates among 16- to 18-year-old students in 4 areas near schools that underwent delays in start time. Two areas saw major decreases (≥65%) in teen crash rates after the delays, while one saw a small decrease (6%), and another saw a small increase (9%). 61

Other Outcomes

There are a handful of other outcomes that have been reported by only one study each. One study saw that students at schools with later start times spent less time at work during the school week (p < .05). 60 More time working has been linked to poorer academic performance. 89 However, the start time study was cross-sectional and other variables such as socioeconomic status may explain the difference in time spent at work. In the cross-sectional component of his study, Edwards found that students at schools that started later reported less time watching television. 57 When he limited his analyses to schools that changed start times over the time course of the study, he confirmed that students at schools that delayed their start times reported significantly less time watching television. 57 Among 197 boarding school students, no change in time spent in athletics or extracurricular activities was reported after a 25 minute delay in start time. 67 Finally, in a small study of 15 students who transitioned from grade 9 (school start time 8:25) to grade 10 (school start time 7:20), self-reported conduct problems and aggressive behaviors decreased with the change to an earlier start time. 54 However, within each grade, these behaviors were associated with shorter sleep duration, which indicates that at least some of the decrease in these behaviors may be due to maturation. 54

Delaying school start times for adolescents has been proposed as a policy change to address insufficient sleep among adolescents, a largely sleep-deprived population, and potentially to improve students’ academic performance, reduce engagement in risk behaviors, and improve health. Nearly all studies to date provide evidence that delaying school start time accomplishes the goal of increasing sleep duration among these students, primarily by delaying rise times. Most of the studies saw a significant increase in sleep duration even with relatively small delays in start times of half an hour or so. Later school start times also generally corresponded to improved attendance, less tardiness, less falling asleep in class, fewer depression symptoms, and fewer motor vehicle crashes. Although not all studies found that later start times corresponded to improved academic performance, no studies found a negative impact of later school start times on academics.

IMPLICATIONS FOR SCHOOL HEALTH

In 2014, the American Academy of Pediatrics published a policy statement urging middle and high schools to adjust start times to permit students to obtain adequate sleep and improve physical and mental health, safety, academic performance, and quality of life, and suggested that middle and high schools not start before 8:30 AM. 3 Schools and school districts cannot make evidence-based policy decision without data. Therefore, research results such as those presented in this review, as well as the recent recommendations by the American Academy of Pediatrics, should be disseminated to school districts, teachers, parents, and other stakeholders. The field still needs rigorous research, including trials with controls, if possible. Many questions remain, such as the issue of how late is late enough? Much of the focus has been on high school students, but biological changes begin earlier, so further research into middle-school students is warranted. More qualitative research about overcoming obstacles to delaying school start times would also be valuable.

Schools contemplating a change in school start time may consider partnering with researchers before a decision is even made. Baseline data on student sleep characteristics, tardiness due to sleepiness, and prevalence of falling asleep during class may be used in the initial decision of whether to delay school start times. Parents and administrators may not realize the extent of the problem of insufficient sleep among their students and this data may help persuade them that some action is necessary. If school start times are delayed, everyone would benefit from collection of detailed data before and after a time change. Not only would other schools or school districts contemplating a change benefit from expanded evidence, the district that undertook the start time change would be able to evaluate the impact of the change and communicate their findings to their stakeholders. Data collected should include not only sleep-related variables and academic achievement measures, but also measures of mental health (such as depression and anxiety symptoms), behavioral problems, risk behaviors, safety statistics such as motor vehicle crash rates and pedestrian injuries, and information on mode of transportation and travel time. Several obstacles to implementing start time delays are often cited, including costs of changing bus schedules, possible impact on athletics and extracurricular activities, and school faculty and staff resistant to change. However, as recently reported by Owens et al. 90 in their examination of school districts that have delayed school start times, many anticipated problems fail to materialize or are only temporary. Several school districts have seen savings in transportation costs after changes made to facilitate delayed start times. 90 Success stories describing how districts creatively overcame obstacles to school start time changes should be shared (for example http://www.startschoollater.net/success-stories.html ) to provide ideas to other districts contemplating change.

High Schools Should Start Later, Report Says

• Share article

Too many high schools and middle schools begin classes too early in the day, according to a report published by the federal Centers for Disease Control .

The CDC reports that during the 2011-12 school year, fewer than 1 in 5 middle and high schools across the United States began the school day at 8:30 a.m. or later, the start time recommended by the American Academy of Pediatrics in a 2014 report. That time is considered the earliest possible in order to allow adolescents to get the 8½ to 9½ hours of sleep each night that health experts recommend.

For their report, published this month, researchers from the CDC and the U.S. Department of Education reviewed data on school start times from the Education Department’s 2011-12 Schools and Staffing Survey, the most recent data available. The survey includes nearly 40,000 public middle and high schools and schools with combined grades. On average, the report finds, schools nationwide start at 8:03 a.m.

The authors argue that school start times are important because insufficient sleep for adolescents has been linked to poor academic performance and to health risks such as being overweight, drinking alcohol, smoking tobacco, and illegal drug use.

The researchers found that no schools in Hawaii, Mississippi, and Wyoming started at 8:30 a.m. or later. But in Alaska and North Dakota, more than 75 percent of schools started at that time or later. The earliest average start time was found in Louisiana, where classes began at 7:40 a.m. The latest was in Alaska, which had an 8:33 a.m. average start time.

OASIS: Writing Center

Writing a paper: thesis statements, basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

Why Sleeping In On School Days May Be Good for Teen Health

C alifornia teenagers can snooze a little later this year, thanks to a newly implemented law that says most high schools and middle schools cannot start before 8:30 a.m. and 8 a.m., respectively.

That law—the first in the country to set statewide mandates for school start times—isn’t only big for California students, but also for public-health experts fighting against what the American Academy of Pediatrics (AAP) has called an “epidemic” of teen sleep deprivation . Both the AAP and U.S. Centers for Disease Control and Prevention have long opposed early-morning class times and advocated for middle and high school bell times no earlier than 8:30 a.m.

Delayed school start times are an attempt to help teens get more sleep , which research shows is a big problem in the U.S. Only about 30% of high school students get their recommended eight hours of sleep on school nights, according to CDC data . Studies suggest sleep deprivation can put teenagers and adolescents at increased risk for obesity, substance use, depression, and poor academic performance, among other issues.

Research has long shown that circadian rhythms —light-mediated internal cues that help regulate sleep—change throughout the lifecycle. That’s, in part, why adults may find themselves naturally rising earlier as they age. Teenagers’ body clocks, meanwhile, are best synced to bedtimes around 11 p.m. or midnight and wake times about nine hours later—a timeline that’s impossible when classes start before 8 a.m.

Early school schedules are largely a holdover from when most families didn’t have two working parents and thus didn’t need to worry about adhering to a 9-to-5 schedule. The juggling act of scheduling bus routes, classes, athletics, and other extracurriculars has kept bells ringing early.

But these schedules are not grounded in science. The mismatch between teenagers’ internal rhythms and external schedules sets them up to fail, studies have long suggested. One 1998 paper found that when a small group of students started school about an hour earlier than they had previously, they experienced “significant sleep deprivation and daytime sleepiness.”

Moving start times back has been shown to have the opposite effect. A 2002 study conducted five years after seven public high schools in Minneapolis switched their start times from 7:15 a.m. to 8:40 a.m. found that the shift allowed kids to get about an hour of extra sleep per night; students also reported better attendance and fewer symptoms of depression. In a 2010 study , researchers examined students at a Rhode Island high school after it moved its start time from 8 to 8:30 a.m and found that students got an additional 45 minutes of sleep per night, while reporting less fatigue and better moods.

More recently, a study published in 2021 found that significantly more Denver-area middle and high school students got sufficient daily sleep after the local school district delayed start times by 40 to 70 minutes. Another 2021 study on Colorado students found that those who started school before 8:30 a.m. were slightly more likely to attempt suicide than peers who started later, though the results were not statistically significant. While more research is needed, and plenty of confounding variables may muddy the link, the findings suggest that starting classes later could improve teen mental health .

But changing bell times isn’t a panacea. A February 2022 research review that examined links between later start times and academic achievement found mixed results, with some schools reporting positive effects and others reporting negative or unclear consequences of the change.

There are also many logistics to contend with. In 2016, public schools in Durham, N.C., moved their start times from 7:30 a.m. to 9 a.m. In a survey conducted the following year, only 26% of school personnel said kids were better rested, and just 14% said they were learning more. Only 13% of school staff and 27% of parents wanted to keep the new schedule. Why? The drastic shift meant the school day ended later, pushing extracurriculars, after-school jobs, and homework later into the evening, and sometimes keeping kids up well past their former bedtimes.

In 2018, schools in Newport, R.I., reverted back to their original start times after a two-year experiment with later bells produced a number of logistical headaches, including difficulty coordinating with nearby schools and scheduling extracurriculars. Transportation can also be an issue, whether it’s rejiggering bus schedules, contending with traffic patterns, or finding ways for working parents to drop off kids later in the morning, some schools have learned after pushing their schedules later .

California teacher Jeremy Adams raised many of these concerns in a January Cal Matters op-ed , adding that the new state law will inconvenience teachers who have to stay on campus for extracurriculars that begin after the academic day ends. “Ultimately,” Adams wrote, “this law will become a case study in ‘unintended consequences.’”

The school start time debate is still an area of active research. A team in Colorado, for example, is studying how changing school start times affects not just students’ health, but also that of their families, teachers, and wider community. And all eyes will be on the statewide shift in California, as education researcher Deborah Temkin told NBC News after the policy first passed in 2019. “If this turns out to be successful, with relatively few consequences, then I think it’s something that other states will likely consider,” Temkin said.

With the academic year only just beginning, it’s too soon to say how the experiment will turn out. But as some California high schoolers told the Mercury News , it’ll take more than a later starting bell to cure their fatigue. “When you’re in high school, no matter what time you wake up, you’re going to be tired,” said senior Anika Bose. “At least I have time to grab a coffee before class now.”
