So there is big gap between my son's verbal score on the olsat and the non-verbal, with the non-verbal being MUCH higher. Not really an issue since he will get getting the WISC again anyway in Septemeber (and I already know a lot about his issues due to when he took the WISC at 6 years old). But, this strikes me as quite odd because I expected the opposite result, i.e., much higher verbal score... Does anyone know what each measures? and is the gap just further indication of a learning disability?
