I suggest moving wherever is the best place for you without this in mind & hiring a very good educational advocate to fight for their rights in that school system. And if they can’t provide FAPE, request to be sent to a collaborative on that towns dime.

There’s EDCO which was already mentioned, and the North Shore Education Consortium that specializes in Deaf/HOH as well, but any collaborative that the town is a part of will have specialized resources. That’s why they exist.
