Thanks for the assistance with my DS12 WISC-IV scores!

We got his WJ-III scores back and they seem to me to be markedly lower than his IQ scores, so was hoping to get some feedback.

The WJ scores had Broad Reading 108, Broad Math 126, Broad Written Language 136, and Total Achievement 126. I have all the subtest scores but am not sure if that's helpful for giving feedback - the lowest scores he got were all in speed-related categories like Reading Fluency, Math Fluency, and Writing Fluency.

His WISC-IV scores, on the other hand, were VCI 162 (using the extended norms), PRI 129, WMI 120, PSI 91, with a FSIQ of 134 and GAI of 155 (using the extended norms).

Is the WJ III scores lower because of speed elements of that test? Or is the WJ III a better indication of where he is and the WISC IV score is the outlier?

Thanks for any thoughts!
