Cathy A: I look at the number of grade skips that you propose for math, and it makes me realize just how far behind in math he would be compared to science. DS would have to go through three sets of double grade skips in order to equalize the math and science grades. Oh boy! That means being with three different groups of friends each year... As soon as he made a new set of friends in a grade he would jump two grades above them the next year. I realize it would only be for math and not for a whole grade... but it still seems hard on a kid that struggles to make friends anyway?

I'm jumping in late here, but from what I've read his math knowledge is already on par with science, right? He'll be making friends, or at least acquaintances in his science right now. If they don't go for acceleration in math right now, I'd ask for the whole jump in math for next year. That'd get him even in science & math next year, he'll know kids in math from his science classes. And let the school know if they don't accelerate him in math this year that you will expect it next year and ask for differentiation in his math now to prepare him for the skip next year.
