Wow Amy!!!!!! That is so frustrating. I would be pulling out my hair. It sounds like you have exhaused the appeals process, so I'm going to guess the next option for you is to hire a lawyer.
That's if you intend to keep in at the school she is at now. Those are some pretty impressive IQ scores for a little lady!
I'm guessing you have already realized she needs more intellectual stimulation than she is getting now.
You could look at private schools or homeschooling.
Our resident expert Kriston has had marvelously positive results homeschooling her so.
Back to the lawyer. Expensive, but people have done it before. I am not a lawyer, but I'm betting that if they provide gifted programs for K and up, your DD's test scores would present a very compelling reason that she SHOULD NOT be excluded from them.
Take a deep breath. Your anger is warranted but will not help you figure out what to do next.
Keep us posted.
