DS9 recently took the WISC IV as part of the entrance criteria for our local G/T program. Their decision is still pending, but I had some questions that the school psychologist who administered the test seems unable to answer fully. Hopefully someone here can help?

First, the difference between VCI and WMI is 37 points. Does that render the FSIQ uninterpretable? Is this a case for the use of the GAI? The GAI I calculated from the subtest scores is 8 points higher than the FSIQ so I think it is worth mentioning in the psychologist's report, but the school admin. is resistant for some reason. Not sure if I should be lobbying harder for its inclusion or is it insignificant?

I was also surprised by a PRI score of 123, which I thought seemed low as math is DS's favorite subject at school and he completes work at least 2 grade levels above his current year. Subtests scores are as follows, I think this qualifies as scatter? BD 12 , PC 12, MR 19. It seems unusual to me that MR is in the highly superior range and the others are just average. I would think a math strong kid would have scores clustered closer together? All subtests on the other indices were within one point of each other, so I can't help but think something is going on with that PRI score. Previous standardized test have put him in the 99% for nonverbal ability.

Any insights regarding the subtest scores and GAI issue would be greatly appreciated. Thank you.
