What were the rest of the scores like?
And did the examiner feel the testing was accurate? My 6 yo is suspected of having ADHD. Apparently during testing he was pacing around the room, seemed very whipped up (which isn't his normal personality) and needed tons of breaks. But they felt he was engaged when he was actually paying attention. Since I know him better than they do and he is not normally hyper, my guess is that he was anxious and acting out, and therefore some of the scores are probably not very accurate. For the non-verbal section he scored 18-19 on Matrix Reasoning and Picture Concepts and 13 on Block Design. They felt that Block Design was an underestimate because his fine motor coordination is very poor, and Block Design is timed and involves manipulating little blocks. For the rest of the subtests he scored in the 10-14 range...it was just those two in the 18-19 range that didn't go along with the rest. Those two high scores brought his GAI up to 133. Full scale IQ shouldn't even be calculated if there are huge discrepancies.
My DD has more obvious ADHD--she is extremely unfocused. I have no idea how she would do on WISC testing unmedicated but I don't dare try it (at least not in terms of seeing if she is "gifted" or not). I do think the scores can be affected--probably some more than others. For some of the subtests, the kid just has to answer short questions, like "What does the word X mean?" In those cases I doubt that ADHD would get in the way much, unless the kid decided they just don't want to deal with the questions and they aren't going to try. But then it should be pretty obvious to the examiner.
