Hi inky,
Stay with the current school, the one that you haven't had to advocate for more challenging work this past year.

Don't go to the creative arts one. Unless your DD is into ALL the different aspects of art right now and *you* want her immersed in it, in that way...

For the creative writing aspect, get a tutor, go to writing programs, summer programs ... what Grinity said above. Just my thoughts on that though.

Best of luck
