Gifted Issues Discussion homepage Forums Twice Exceptional 68 points between PSI and GAI! Disability?

Hi. Totally New to this board, but here is a report from the Gifted Development Center that is totally on point for this discussion:

http://www.gifteddevelopment.com/About_GDC/whoaregiftd.htm

The WISC-IV VCI and PRI are much better predictors of giftedness than the WMI and PSI. The article gives specific ranges for differences that indicate the full scal IQ on WISC will not be accurate. E.g. if Index score on the four composites show delta greater than 23, the FSIQ is not accurate.

This article is a MUCH easier read than the WISC Technical report, which was a real slog to understand.

Good Luck.
