About Class Wake
Shifts in the sleep-wake cycle at puberty mean that most adolescents get their best sleep between 11 p.m. and 8 a.m. The American Academy of Pediatrics, Centers for Disease Control and Prevention, and American Medical Association all recommend that middle and high schools start class no earlier than 830 a.m. to allow students to get healthy sleep

Our analysis of sleep also indicates that later start times affect students' wake-up times but not bedtimes thus, the effect of later start times on nighttime sleep comes about entirely through a delay in wake-up time rather than a change in bedtime. The new law requires public middle schools to begin classes at 800 a.m. or later and

As of 2011, the median start time for American high schools Using this random variation, they nd that having a start time of 700 a.m. versus no class in rst period decreases achievement by about 0.15 SDs in that class, and by about 0.10 SDs in subsequent classes. 2.2 Sunlight, sleep, and
Pushing back start times has a direct impact on how much kids sleep. It's no surprise that teens wake up later when their school day starts later. Notably, though, they tend to go to bed around the same timeresulting in more time under the covers, as Meltzer, Wahlstrom, and colleagues showed in a longitudinal study Sleep, Vol. 44, No. 7
Even so, as Wahlstrom recognized following the start time delays in Edina 720 a.m. to 830 a.m. and Minneapolis 715 a.m.to 840 a.m., 3, 37, 322 quotthere is clearly a statistical relationship between these two variables that may be explained by other variables e.g., less depression, less struggle to stay awake in class that change
The frequency of instances in which students failed to wake up in time for class was evaluated by pooling data across participants for a given class start time. Two-sided chi-squared tests

Sociodemographic and behavioral predictors of bed time and wake time among US adolescents aged 15 to 17 years. J Pediatr
Most classes are taught really quite poorly. I used to describe my brain as a big flywheel that took a long time to speed up and a long time to slow down. You can arrive at that base on a quotwhen people wake upquot graph, but such a graph also gives a lot more information
In the next academic year Fall 2009, students in third grade moved from a previous start time of 910 am to 745 am, whereas students in grades 4-5 switched from a start time of 820 am to 745 am to accommodate a switch in the start time for middle and high school students from 730 am to 815 am. At the end of this academic year Spring
