During the second half of the 20th century, many public schools in the United States began shifting instructional time earlier than the more conventional bell time, thoughtout 9 a.m. Today it is common for American schools to begin the instructional day in the 7 a.m. hour and end about seven hours later, around 2 p.m. ...
Most schools finish between 2.30pm and 3.30pm. It varies, and there are outliers, but those times give you an idea. Often, a school that starts early (8.30am) will also finish early (2.55pm). We had morning registration at 8.45am and finished school at 4pm, getting home about 5.30.
Shortening the school day could give kids and teens more time for movement, brain breaks, and other activities proven to boost learning outcomes among other benefits. With more opportunities to move around and worry less about following classroom rules, kids could be better prepared to focus when it counts.
Better sleep: Delayed start time could help teens sleep during their natural sleep/wake cycles. Less caffeine: Teens may be less likely to depend on caffeine to stay awake during the day. Better grades: Adequate sleep could help teens be more alert during the school day, which could boost their academic performance.
How much sleep someone needs depends on their age. The American Academy of Sleep Medicine has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours.
Elementary school is kindergarten through 5th grade (ages 5-10), middle school is grades 6-8 (ages 11-13), and high school is grades 9-12 (ages 14-18).
Teenager's circadian rhythms – the cycle of sleep and wakefulness – typically begin two hours after adults. Neuroscientists say they are biologically predisposed to go to sleep around midnight and not feel fully awake and engaged until between 9am and 10am.
According to the National Sleep Foundation, a fourteen-year old needs eight to ten hours of sleep per night. I strongly suggest you hit the sheets no later than 10:00 PM every evening. If you get the recommended sleep you'll feel more energy during the day and do better in school.
The body releases the sleep hormone melatonin later at night in teens than in kids and adults. This resets the body's internal sleep clock so that teens fall asleep later at night and wake up later in the morning.
For teenagers, Kelley says that, generally speaking, 13- to 16-year-olds should be in bed by 11.30pm. However, our school system needs a radical overhaul to work with teenagers' biological clocks. “If you're 13 to 15 you should be in school at 10am, so that means you're waking up at 8am.
It's natural for babies and children to want to sleep with their parents, or very close to them, as it's a primal thing to do. A look at young dependent mammals will attest this - they all sleep next to their parents/mother.
Recent studies indicate that near epidemic proportion of children are co-sleeping with parents today. According to Parenting's MomConnection, a surprising 45% of moms let their 8- to 12-year-olds sleep with them from time to time, and 13% permit it every night.
To start with, it's not just about your kid's age or whether other kids their age have phones. An immature 15-year-old may not be able to handle the responsibilities that go with a phone. That includes understanding everything from how charges can add up to how access to social media will affect them.
Bedtimes by Age

|15 months – 3 years||12-14||6:00 -7:30|
|3 – 6 years||11-13||6:00 – 8:00|

Sometimes life calls and we don't get enough sleep. But five hours of sleep out of a 24-hour day isn't enough, especially in the long term. According to a 2018 study of more than 10,000 people, the body's ability to function declines if sleep isn't in the seven- to eight-hour range.
Staying up late is part of a natural transition from childhood. The internal clock of teenagers tends to shift about two hours later than when they were kids, though they still need eight to 10 hours of sleep. That is why many sleep scientists campaign for high schools to start later in the morning, Dr. Sterni said.
School-age children should go to bed between 8:00 and 9:00 p.m. Teens should try to go to bed between 9:00 and 10:00 p.m. Adults should try to go to sleep between 10:00 and 11:00 p.m.
