There isn't a huge difference in the scores. Both NNAT and CogAT have a low ceiling, and they really can't discriminate between a 99.5th percentile kid and a 99.99th percentile one. The difference between the two scores is one lucky guess. NNAT is also known to have inflated scores at the top. It sounds like WISC is in line with the other scores if the subtest scores match up reasonably well. The test scores and the WISC inclusion were not your problem. The GBRS was the problem. |
+1 Another “cold” test-taker in our house, too. |
| We did not prep and got in. Moved from another state (public school) that was big on equity and they don’t even tell you when the test will be given. Only learned about it when we got the score in the mail. Plus this was our first kid so we didn’t know anything. |
