Good points, all.

I feel that if the new norming study drastically changes how any previous WISC-IV scores are viewed, then the entire test should be revised. Maybe the new norming study should apply to a WISC-V so that there is no confusion.

Can you see any of us explaining to some GT administrator, "my kid's 148 score really IS in the 99.9th percentile, because he took the test before a certain norming study was released"? Huh??
