DD did very well on one version of the CogAT and a little more than a year later on a different (timed) version, she bombed it (except for the verbal section, which she completed). Was the version timed? If so, see if you can figure out how many questions were answered. DD did a timed version in second grade.
We had her tested privately and her general ability index on the WISC was 150. On the CogAT she was barely above average. Same exact thing happened to one of her friends. They were both too slow and careful with their answers and didn't work within time limits.
