I have always been under the impression that a medical diagnosis out weighs the what the school says because they cannot diagnosis your child. My oldest has a medical diagnosis of ADD but the school didn't find him to be inattentive and wouldn't give him an IEP and I had to fight to get a 504 for him to state that he must be tested in a quiet environment, sit towards the front of the room in a desk that faces the black board, etc. I you feel he needs more then fight for it. You can tell them you want a private eval done because you disagree with theirs we will be doing this if our OT, speech pathologist, and ei service coordinator can't talk our school into preschool being the best option for Evan when he turns 3 in April because I know our dr also backs this. My friend's little boy is very high functioning autism and he recieves 5 half days a week of preschool and goes I believe 3 days a week during summer months.
