For the WISC, I see some high/near ceiling subtest scores (19s, and perhaps 18). Was he eligible for extended norms? If he is and they have not been used, this could be useful information when being considered for such a program.
Also FWIW, DS had the WISC/WIAT performed at the same time with a discrepancy analysis. His lowest scoring area on the WISC was the PSI, so his GAI is also supposed to be a better number for him. On the WIAT, his performance was MUCH closer to his GAI than his FSIQ. So far, his other achievement scores have also followed this pattern.
