I had a little boy in my class last year who was the same, I gave him the academic excelllence award at the end of the year because he was by far the smartest in the class, we worked on a psecial social skills program with him which has helped heaps. Does your son have any specialist people coming into school to help?? We have a specialised Aspergers teacher come in once a week with X so she can go through social stuff.
