Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Extended norms?

Hi,

Some of the recent posts about IQ scores with extended norms have piqued my curiosity. I was wondering if AEH could calculate them for the WISC-IV for my DD who was 10 years, 4 months at the time of testing.

I would be happy to, but I'll need the raw scores to do so. They should be on the report, most likely in a table, in the column to the left of the subtest scaled scores. VCI looks like it could be affected, as does mr. I -can- tell you that if she solved every item on Matrix Reasoning, her subtest extended scaled score would be 23, which would make the PRI 147. However, typically, the Extended IQ/Index score is recommended if there are two subtests that max out on the scaled score. And she only has one in PRI.

Thanks for your quick response! This is all of the information that I have, so it sounds like they can't be calculated unless I go back to the tester.
