Thanks, Dottie. Some people raise alarm at scattered scores, so I thought I should check, but your reaction seems very sensible. While the subtests each measure something, with some error bars, my son is doing fine with his particular combination of strengths and weaknesses (or averagenesses), so there's no real need to worry.
His FSIQ [removed] got dinged by the lower subtest scores, as did his GAI (which they didn't calculate but I figure it's [removed]). Perhaps you could invent a new "Dottie index" using "the subtests that I personally think are most telling of cognitive ability". His six good scores ([removed]) would give a much better number.
As for DYS, I only came across this forum when searching for information on WISC scoring, after the test but before getting the scores, so I hadn't heard of DYS. But he really doesn't qualify on the Option 1 Qualification Criteria, so I wouldn't try even though I suspect that his IQ is somewhat higher than the test shows. He'll have plenty of chances to try to prove his abilities in Talent Searches and Mathematics Competitons. (We'll emphasize with these tests, that he should relax and have fun, but that they are also important, just as we did this time.)
One question is, does he ever need another IQ test? He doesn't need it to convince the school of anything. The school is fine with acceleration and anything else. Another IQ test would be like a "second opinion". And it might be a reasonable price at a university Psychology department (the first one was paid for by the school). But is there a need other than for curiosity?
As for the Mathematics achievement scores, I really think they must have some callibration problems in the tails of the distribution. I agree with the >99.9% percentile, corresponding to scores of 150+, but the specific numerical scores don't seem realistic to me.
