Oh, and I should jump in to agree with Dottie. My last post was more about IQ tests in general and not to say that the scores your ds got on the WPPSI are inflated. If he hit the ceiling on multiple parts, even if the test is at the end of its life cycle, I do believe that you can safely say that your dc is very, very intelligent. I'd just be less comfortable with the SB-LM b/c it is much more outdated than the WPPSI-III and, in that instance, I do think that you can wind up with numbers that are significantly less meaningful and informative.
