IQ results... Can anyone explain this to me?

Gplusk, a 10 is the mean score on each section of the WISC. A 17 or higher is in the 99-99+% range. It is possible to get every question correct in a subsection and not get a 19. On the Performance subtests, speed is often an important part of the score, so a child who works slowly and accurately may get a score that’s lower than what might expect. Just so you know, adding all the subtests doesn’t give you the IQ score.

My recollection from when my kids were tested is that age 13 is a a bit old for the children’s version of the WISC. Was there a particular reason for your brother being evaluated?

The full scale IQ may not be accurate for kids with a big spread between Verbal and Performance. In our case, another test was administered that was not as speed-dependent, and its score confirmed the Verbal WISC scores should be regarded as a minimum score for him. The IQ testing certainly did not give us a full picture of my son, though it led to other testing that showed us the other issues. (A 6 in coding will tend to do that.)
