The idea

The American Academy of Pediatrics urges middle and high schools to start no earlier than eight thirty in the morning, citing adolescents' insufficient sleep.

In practice

Later start times linked to better attendance and less tardiness, sleeping in class, depressive symptoms and car crashes.

Where people slip

Many schools still start earlier; changing bus schedules and logistics has proved difficult for some districts.
