I'm a big fan of the idea of starting school later for high school students.
As studies show, teenagers' sleep schedules change. They tend to go to sleep later and wake up later. Yet high schools tend to begin classes earlier than elementary schools and middle schools.
Here in CorruptSmallTown, the high schoolers and middle schoolers are at the bus stop in front of my house at 7:30 am. My kids go to the elementary school across the street for a 9 am start. I think we should switch the schedules around.
High school should start at 10 and end at 4 or start at 11 and end at 5. They will get home roughly when their parents do. They won't be getting home at 3 and spending 3 hours alone until their parents get home. They will be spending that 3 hours in the morning home alone. But doing what?
Staying out of trouble.
Extracurricular activities could be rescheduled for mornings. If you want to be involved in Model UN or Glee Club or Football, you do it in the morning.
I think it's worth a try.
