> So teenagers get the first bus, then middle schoolers get one an hour later, then grade schoolers. Where I grew up it was the opposite. Grade schoolers started first at 8:00, middle-schoolers at 8:30, high-schoolers at 9:00. As a high schooler you finish school at 4PM, hardly a very late school day. Younger kids naturally go to sleep and wake up earlier than teens anyways, it's not unfair or harmful to have them start school earlier.
