Thanks RevMom, I am going to ask the OT if she has given him that test. The other part of the story that I didn't add in to my original post is that I am also concerned that his sensory issues may include some visual and auditory elements. I am going to have him evaluated for CAPD soon, which I wonder may have affected his CogAT performance because the teacher reads the questions to them. And if he didn't hear the question, I don't think he could ask for it to be repeated (and even if he could, I don't think he would!). And, although his reading level is significantly above grade level, he does not have alot of stamina when he reads. The OT is working on him with that too, because visual therapy is just not something we can afford right now. So, it all leaves me wondering how much these things affect his output and worry that at some point, if we don't address them, he will just shut down and just skate by, which he easily could.
