Hi, my DD8's WISC-IV profile from age 7 is very similar to your DS's. I'm curious to hear what he is like in general.
Our testing psych specialized in gifted children and said he rarely saw GAIs in the 150s. I was too stunned to remember much else, except when you see a 19 it is very significant...it means he got everything right and they ran out of questions to ask. Our raw scores show a 19 being an age equivalent >16:10.
I think two 19s would qualify for extended norms. In DD's case she had one 19 and two 18s, and extended norms pushed her GAI 5 points higher.
