I'm not sure if I'm reading this WISC summary correctly, but it looks like his subtest scores are:

Verbal Comprehension 35
Perceptual Reasoning 30
Working Memory 21
Processing Speed 21

I have no idea what these numbers mean. The person administering the test was a grad-student. I remember him telling me the test was going to take "x" amount of time, but my son ended up finishing way early...maybe an hour earlier than expected. I had wondered if he just got tired or bored of doing the test, but being a new mom in the school system I didn't really question it.
