I am fairly sure that an ASD diagnosis never goes away. What might go away are visible manifestations.
The big thing for us with AS is social interactions. The thing is, from what I have read it is something that can be compensated for if the skills are taught -- the child with AS can then consciously pay attention to non verbal social clues and consciously apply the correct answer. The more intelligent the child, the easier it is to do (although it does remain hard work).
I am surprised that the person who evaluated your son didn't go and observe him in the classroom. I will also confess that reading our report I felt like our psychologist had deliberately chosen to put the worst possible spin on our son's behavior. That said the diagnosis is a fit (looking back, it might even have been a fit for me, although I am still unclear on the difference between AS and gifted -- and yes, I have read that document in the resources five times already). Or it is for now.
