It depends on your child's needs. Many districts are great as long as your child does not need significant supports, others are better if you need more. If you need significant supports, you will likely have to be ready to fork over $$$ to live in those towns. Ours has been great with my son, but he is in an integrated classroom with minor support.
Edit: If you have not already joined the RI Special needs group on FB, that is a good place to ask as well. They are boots on the ground so to speak. You will get a lot of folks who are eternally pissed off though.
