I would definitely start waking her for the time she needs to be up for school. I wouldn't force her to stay up late though. Some days she might be played out and fall asleep at supper, or on the ride home from school. Other days she might get a second wind and make it til bedtime. The consistent waking time (7 days a week til she's used to it), should reset her body's rhythm, and hopefully the evening will take care of itself as she adapts and grows.

You didn't mention any-but if she does extracurriculars, I'd avoid any after school classes for the fall.
