I think you hit the nail on the head, calculating the GAI for DS would equate to doing it for all who fit the profile. At this point, DS has a qualifying score for services but our district is quite competitive so not all kids who qualify will be offered services. I was thinking the GAI could possibly strengthen his case. But since looking closer at his subtests I think my bigger concern lays with the PRI scatter. Even if he qualifies for services I can't help but wonder if there is an LD or other issue going on there that was previously unnoticed. And its also quite possible I am overanalyzing the whole thing!
