Have you considered part time homeschooling? IF the situation is not looking good in December you could consider doing a trial Homeschool for half a year and see how she likes it.

My kids did not want to change schools, because of the distance and friends. I made the final decision, saying we would try it for a year. They are much happier in their gifted school.

Are there any other school around that you could drive her to? Some private schools have finacial aide if that is an issue.

Have you found a state or area gifted association? They may have ideas for helping her.

How about applying to Davidson?
