Thanks all. I am pretty sure he took the 2-5 test. School does not provide a RIT for the class but I believe there are kids in his program with similar scores. I get the feeling most/some those kids are in outside of school tutoring and other programs. His score is with no enrichment other than reading math books on his own, and zero acceleration at school prior to this year. Mostly I was wondering if these scores are really that high and what if anything to do about it.

Our school system has a single above grade level math path and that is what he is on. The math is moving much faster this year in the GT program so he is happy about that, although he would enjoy more of a challenge if it was available.

Thanks everyone for the advice.
