Bad plan. Go to bed earlier instead.
That is not the way middle schoolers are wired. Their circadian rhythms are jumbled, just like a lot of other things going on in their bodies during this transition time (from childhood to young adults). They are wired to naturally fall asleep around 10PM - 12 midnight, and rise nine to ten hours later. Their brains start processing information an hour or so after rising.
Then, around age 16, things start settling down again, and the early to bed, early to rise adage holds true.
IMO, homeschooling during the middle years, when a family can adapt to the needs of the individual, is the best plan. I would rather not fight a battle over a self-limiting condition.
