I am not experienced with autism/aspergers, although, I do know a little about the testing. We suspected my nephew of having dyslexia, and knew that the ISD would test him also, and of course he was already enrolled in school, although we found out that even if their to young for school, as far as the testing goes, they have to be enrolled so the state could pay for the tests. Another thing is the school is not allowed to tell you where you should go to get help after the school testing is complete or they will have to pay for it, BUT if you do a little research, and find out about a hospital or facility somwhere that will do further testing, and suggest treatment, and YOU tell the school you want to send him there to be tested further, THEY have to pay for it.
My nephew test came back saying he did in fact have dyslexia, and becaue my SIL's mom is a school teacher at another school, she gave her the information to use with the school, so my SIL's told her ISD that she wanted her son tested further at Scotish Rite Hospital for his learning disorder, and the school sent him, and paid for further testing, and the Hospital gave him the tools and information he needed to succeed. All because she asked them to send him. Keep in mind, the ISD will NOT suggest anything, not because they don't want to, but they are not allowed to, because they will have to pay for it, so it is going to be up to you to research the best options that are available, and approach them about it. It's a struggle I know, but so worth it in the end.
I know that wasn't very encouraging, but I hope it helps you in some way.
