We often hear that it tests lower than individual IQ testing, but I came across a case recently where the kid had a ceiling Cogat score but was deemed "not gifted" (low 120's) on the WISC-IV.
Our experience with dd9, as Dottie knows, was that her CogAT was much lower than IQ. In re to the case you cite, though, do you actually think that the CogAT was an overestimation or that the WISC was an underestimation? I find this topic curious b/c one of our local school districts takes the approach of assuming that the highest score is accurate even if none of the other scores support that and the other takes the approach of looking at the lowest scores and often discounts high scores.
