You can't really request specific tests because each school district uses whatever THEY find the most helpful, or in some cases whatever is the cheapest & easiest. All you can really request is areas you want tested.
It wouldn't hurt for the school to do the Autism Spectrum Disorders (ASD) testing also. It just surprises me that he doesn't qualify AT ALL on the spectrum given what you've shared with us. But, if those specialists tested for that specifically then I guess you can't argue. It might be that as he gets older, the signs will be more clear if it is any level of Autism Spectrum Disorders (ASD). I don't remember difficult child 1 back that far so guess I can't tell you one way or the other. I just know it sounds a lot like difficult child 1 as he is now. You're doing all the right things. Keep plugging away and the answers will eventually make sense. On the other hand, if YOU suspect Autism Spectrum Disorders (ASD) of any kind, what you'd normally do to help kids with it works for all kids also. It definitely can't hurt.
