I'm going to allow DS to take the CogAT and I'm hoping he does better on it than the WISC! There have to be some people who do better on an IQ test and some that do better on an ability test. We'll see how it goes. He needs a higher verbal score than what he got on the WISC and I'm hoping the multiple choice format will work to his advantage since he's not very expressive/articulate. He may very well be one of those boys that does super well on the quant and/or nonverbal sections. I detest the CogAT because it was a horrible test for DD and her score bore no resemblance to her WISC score, so my fingers are crossed.
