What does your dd want to do? I think that will play a key role in your decision making process. If she is already accelerated and wants to accelerate in math again, I would go for it.

I was just about to say the same thing. Is your DD pining away for the skip, eagerly chomping at the bit to get at the higher math, or is she basically content and thinks that a skip would be fine (or some variation of that)?
The test score is SO close. It comes down to rules Vs. passion. There's a lesson for her either way: a) complying with established criteria or b) fighting for what you want. Both lessons have value.
If she's anxiously hoping and praying to get the skip, I'd fight for it.
