Some interesting data is highlighted in this NYT article showing the correlation between later start times for schools and better sleep for teens. The study, in Science Advances, also found that the change was associated with a 4.5 percent increase in grades (although the researchers could not prove it was causal). They also found an increase in punctuality and attendance with later start times. As KAIS has been at the forefront of this issue, we are happy to see other schools around the world following the science and adopting later start times.
