Hi,

My son (12) had taken the InView in 5th grade and the CogAt this past fall (7th). I believe they are quite similar as they each attempt to measure verbal and nonverbal (quantitative is included in nonverbal on the InView) reasoning abilities.

I can�t comment on how they compare with the WISC as my son has only taken the SB, but all three �cognitive abilities� tests yielded consistent percentile ranks in his case.
