Also, you can start throwing around comments like "I'll have to check with my contact who works for the State, in due process, before responding to this" (or something along those lines). Show them that you are not going to blindly accept whatever they decide, and scare them a little bit. This worked wonders with my first child and after the first initial resistance and refusal to evaluate, the school was scared ******* when they figured out I had talked to someone with the state. I never filed a complaint, I just made a phone call, and made it clear to the district. I expressed to the school how confused the woman in the Dept of Ed was, by the school's refusal to evaluate.
