Hey, that's a good idea. I think that could work. I assume the coursework is online? Maybe other readers might now of additional secondary schools with online coursework.
The only other option I can think of is to homeschool your daughter at her appropriate level until she reaches high school at which point she could hopefully place into classes at her level or take college level work as necessary. (For some reason the high schools seem to be more open to allowing college coursework. I don't know what they think these kids will do until they GET to high school. They don't just magically become gifted when they reach 9th grade, suddenly able to jump into college math in a single bound--at least most of the time!
Good luck with your talk with the Director next week. Let us know how it goes. I'll continue to think and research on this---
