I guess it was mostly correlated, but we also saw some unusual (wide spread) of results on WISC. On COGAT, dd got high 140s (very high on quantitative) and on WISC V, she saw scores from 120 - 150 (very high on verbal). So the scores were all over the board. But overall, the teachers / educators determined that she was gifted and at the higher end of giftedness.
