Angie, sorry to hear about your struggles. Seems like more often than not, schools create more barriers than opportunities for gifted kids. How frustrating!
I was surprised at how open to acceleration our school district is. If DD isn't a good candidate for whole-grade, then we'll look into single subject acceleration and perhaps skipping 4th grade next year. Not really sure yet until some testing comes in. Also, DD8 seems nervous about going to 4th grade after the winter break--I think reality has hit her and she's scared to meet a new teacher, new kids and think she's expected to "know" everything already taught in the class.
At any rate, I'm grateful DD is getting attention paid to this issue, and if she doesn't accelerate this year, at least other things can be done to help challenge her.
