So how early is too early when it comes to when classes should start each day for middle and high school kids?

The American Academy of Pediatrics said this week start times for middle and high schools should be pushed back to 8:30 or later. The pediatricians put it this way: "Doing so will align school schedules to the biological sleep rhythms of adolescents, whose sleep-wake cycles begin to shift up to two hours later at the start of puberty."

And U.S Education Secretary Arne Duncan apparently agrees, telling NPR a lot of the research as well as common sense shows that a lot of teenagers struggle to get up at 6 am.

And the Education Secretary says quote: “So often we design school systems that work for adults not for kids.”

In other words, he’s saying that to make it easier for parents’ work schedules, schools have traditionally set up start times that are not the best for teenage kids.

Maybe that’s a call for employers to offer for more flex time and maybe it’s a call for parents to try to put their kids first.
