They want everything to be nice and matchy matchy. Like the GT coordinator last year telling me that DD's WISC math score would need to match her math achievement score with both being above 98th percentile. Same with reading. They want reading achievement to match verbal on the CogAT. Luckily it was via email or she would have found me yelling "What are you talking about! You're going to pull her arithmetic score from the WISC and use that as evidence of math reasoning?!" So if they use a kids' non-verbal score from the CogAT, it's not going to "match" any achievement score. And therefore it's a problem for them and their matrix so why not just eliminate? Like i said, it's speculation at this point but I talked to someone I trust to have somewhat valid information.
