Whatever you do - put it in writing and make a copy for yourself. Document everything and create a paper trail.
I'm in MA and there's no state mandate to provide gifted services. Legally, the MA schools are only obligated to provide a general curriculum. Now, I've heard some cities and towns do have g/t programs here and there, but there's nothing on the books across the state and you are still at the mercy of the school district and any localized policy regarding g/t accommodations.
My 2e/pg son has already been in two private gifted schools here and neither one would/could accommodate or rapidly accelerate him. IF you've got a child who is operating 2-3 grade levels or is advanced in one or two subjects, you'll be in better hands in trying to get any accommodation.
