As the parent of a high school freshman boy, I've observed that his demand for sleep seems to have recently gone up, but so has his school work load. He's regularly up until 11pm doing homework as it is, and waking up tired at 7am the following day. If they simply shift his school start and end times 30 minutes later, I don't see much net benefit for him.
