DS had a much lower working memory (digit span 9) and processing speed scores on the WISC and the psych was ready to give him an ADD label. But on the SB5, he hit the ceiling (19) on verbal working memory. In this case, it became clear that DS thought the WISC tasks were really really boring and loved the SB5 tasks, so he engaged.

I don't think we can label him with a disability, but it is clear he has trouble working through things that are boring and that quality will pose a challenge to him. But I agree with the folks who are saying that a discrepancy on one IQ test is hardly the whole story.
