Gifted Issues Discussion homepage Forums Parenting and Advocacy Update on my dd/gifted program/question about WISC

Aeh, what about those who had 1 19 and a bunch of 17s and indices in the 140s? Is the thinking that extended norms might make a little difference but not a significant one?

George, yes, that is the thinking. You would only be able to apply extended norms to the single subtest with a 19. The maximum scaled score possible, even with extended norms, would be 28. This might have a moderate effect on the index score in question, but a negligible effect on the FSIQ. The trade-offs with switching to the extended norms, which were developed from a fairly small norm group of HG+ children (versus the standard norms, based on thousands of data points), are not worth the relatively small improvement in spreading the curve.

sigep,

The equivalent to a CSI of 132 is an FSIQ or GAI of 130 on the WISC-IV. The GAI should be considered seriously, because there are no equivalents to the WMI and PSI portions of the WISC-IV on InView.

Great thank you aeh. I just want to make sure the school is on the same page. I don't know why they aren't committing to a score on WISC and giving me numbers from InView. It is making me question what they are doing.
