Without subtest scores, and really, without a more thorough evaluation, it is really difficult to tell if there is some disability (ADD or something else) that is depressing the IQ scores. The FISQ and even the GAI don't give anything like a perfect measure of giftedness.

My son presents like he is ADHD/ADD, and his FSIQ is nothing to get excited about, but he has exceptional verbal gifts. His score profile is remarkably "spiky", so the deficits mask the gifts when you add everything together. It would be a grave mistake to take his WISC FSIQ/ SB-IV composite score as a measure of his abilities, though. He is highly gifted, but with disabilities.
