Thank you ElizabethN. We are not having problems right now, we were just looking for some answers to better understand him. When we met with his school to look into how we could better meet his needs (especially in math) they made comments like, "he's an anomaly" and "no other students like him". They (public school) were accommodating and moved him up 2 grades in math, which he is thriving in. Some comments were made that he seems to just be really good at math, but we suspected it was a little more than that. We are however, a little shocked at his scores and need to process exactly what to do with them. :-)
