giving tests in the first half of the morning

Then there's the question of sleep. Ideally, schools would change their schedules so teens could start their lessons later, and they should avoid giving tests in the first half of the morning. "I feel very strongly that schools have to start thinking about this," says Coleman. At the very least, teachers and parents should give teens some slack when they seem drowsy in the morning. They are experiencing something akin to jet-lag – and the last thing they need is more stress to add to their burden.
