Thanks for the info. I googled the extended norms for the WISC and used the raw scores (I have the front page of the test it was stapled to the report) and it raised her GAI by 9 points, so the WISC GAI with extended norms is 155 , so more consistent with the other scores. 22B I do not know the answer to that one, maybe someone else will chime in. However, if different tests measure different things it does make since that someone would want a test that played to their child's strength. It's not like your teaching your child a test ahead of time and apparently they are both widely used. DD said she thought the SB was more fun, whatever that means.
