Thank you for all the thoughtful advice. I'm processing it and will get more information from the schools this week. I came across this and realize why it's been so hard to decide...she's a mix of all three:

The advice to keep her at the academic school sounds good when I think of that side of her and vice-versa when I think of her creative side. I've also realized the friends she really clicks with also have a strong creative side. Her best friend was accepted and will go to the creative school while some other close friends are on the waiting list. On the other hand, I think she's susceptible to learned underachievement and the academic school will help her avoid that trap. Not sure how the creative school would play into that and that's my main reservation with switching. What to do, what to do... crazy
