This sounds similar, although not exactly, what we went through with sd/my son last month. My layman's opinion is this: If they don't want to accept the last eva's anymore, they can do their own, and make sure they assess ALL areas of suspected disability. I would not sign release for them to talk to therapist. If he can be useful, maybe you can get him to write a letter and take the sd the letter yourself.
Bologna on the "time to move on". Disabilities don't always "move on" and they are still required to accommodate them, in my humble opinion.
