I mean I also don't give my son caffeine (because he's 2) so this seems like a reasonable assumption.

Teenagers stay up too late anyway so I'd say this sort of thing would be a good way to hopefully reduce the effects of sleep deprivation.

Teenagers have to get up too early. Teenagers experience a shift in their circadian rhythm and also require more sleep than before puberty. School schedules do not account for this shift.
