Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Another Newbie Question - WISC-IV Extended Norms

We had the WISC-IV performed on my DS6. He reached the ceiling on the Matrix Reasoning Test. The psychologist did not use Extended Norms, but I just read something about them that suggests she should have....Is this true? He received a raw score of 26 and a scaled score of 19 on the Matrix Reasoning test.

Thanks!
