Thank you for adding the things you have tried so that we would not be repeating those as suggestions... We have one that got a pseudo evaluation by a lady at the county health department, she cannot diagnose any disorders but was able to give us many many ideas of which way to go as far as trying...like letting him rock when he's upset, or jump/bounce...that winds him up like he's a clock, he is wound up for hours and hours and hours after bouncing. Using a backpack with some books in it worked for quite some time. It grounded him and when he had it on he was able to stay in the group and pay attention very well. He started getting teased and started refusing to wear it so they stopped trying.
The lady was able to give us information about OT/PT and how it might work, it didn't in our case though. It was a lot of good quality information that has been our source of references quite a few times.
I think getting the school to provide an evaluation is your right and they have to pay for it. We took a class last night on IEP's. You have the right to make your school pay for this and if you formally request it in writing they have only a certain amount of time to respond and do it.
I googled: getting help to get an IEP for my child through school
