Thank you blackcat. I had read the position paper but had not considered submitting it in support of using the GAI. Were it not for the BD and PC subtests I wouldn't be as concerned. I am afraid those scores may red flag him as comparatively weak non-verbally when achievement wise that is just not the case.

Fine motor skills could definitely play a part with the BD subtest. DS has always been a bit weak in that area. Processing speed subtests were in the superior range so I don't think that is the issue. So the PC score is still a puzzle to me. Thanks again for responding.
