Hormonal changes, in particular, the secretion of melatonin, shift the natural circadian rhythm of adolescents, making it increasingly difficult for them to fall asleep early in the evening.
Sleep, circadian rhythms, and delayed phase in adolescence. To deal with this potential problem, my second approach focuses on schools that changed their start times during the study period. Previous research tends to find that students in early-starting schools are more likely to be tardy to school and to be absent.
Of course, increased sleep is not the only possible reason later-starting middle-school students have higher test scores. As a result, it is not clear if there is no effect because start times are not a factor in the academic performance of prepubescent students, or because the schools start much later and only very early start times affect performance.
However, elementary schools start much later than middle schools more than half of elementary schools begin at 9: Finley Edwards is visiting assistant professor of economics at Colby College.
Since buses serving magnet schools must cover a larger geographic area, ride times tend to be longer for magnet school students.

This is not at the cost of teaching time which has remained constant but at the cost of natural breaks, which has led to reduced lunch times and lesson breaks. Not engage in daily physical activity. Wake County is uniquely suited for this study because there are considerable differences in start times both across schools and for the same schools at different points in time.
As the researchers note, even U. Students in early-starting schools could be more likely to skip breakfast. And how would that affect after-school jobs, athletics, and responsibilities to look after younger siblings?
To further investigate how the effect of later start times varies with age, I estimate the effect of start times on upper elementary students grades 3—5. Since the effect of later start times is stronger for the lower end of the distribution of test scores, later start times may be particularly effective in meeting accountability standards that require a minimum level of competency.Researchers analyzed data from more than 9, students at eight high schools in Minnesota, Colorado, and Wyoming and found that shifting the school day later in the morning resulted in a boost in attendance, test scores, and grades in math, English, science, and social studies.
