My daughter has been in charge of her own sleep schedule since she was 6. As long as she got up on time and wasn't rude from lack of sleep, and her grades stayed good, I let her go to bed when she wanted to. She usually had herself in bed by 9 or 10. By the time she was in high school, she cut that back to 8 or earlier. BUT... I drive a school bus, so we were up at 5am. I do have to say, that her being in charge of her own sleep schedule makes me feel better about her making it to her early morning classes on time now that she is in college. Since she never had to rely on me at home, it's not new to her now that she's gone. Granted this isn't for every kid, but it worked for mine.
