I am a bit puzzled by the calculated GAI. That is not the same number I obtained. Nor is the FSIQ, if it comes to that (though only different by a little). (The Primary Index scores are all consistent with my calculations.) The GAI number you listed appears to be the lower limit of the 90/95% confidence intervals for the GAI, rather than the actual standard score.
Arithmetic would not affect his GAI. I think (if what you've posted is an accurate reflection of the submitted neuropsych) that a typographical error may have been part of the rejection. I'd suggest going back to the evaluator and clarifying. The GAI should be DYS qualifying.
