I also do not totally trust the WM subtests on the WISC. DS's were well below average on the WISC. But he hit the ceiling on the WM on the SB5! So is WM is just fine (better than fine) when he is engaged. The problem (as we saw on the WISC) is that if he is bored he does not engage his WM! He almost got an ADD diagnosis on the WISC, which probably wouldn't have been fair considering his 19 on the similar test on the SB5.

He is a dawdler, but only when he is bored.
