No, DS didn't click with tester. We both told the tester he was anxious and had social anxiety that prevented talking, but the tester said there were no signs of anxiety because he wasn't fidgeting, biting nails, twirling his hair, etc.
DS said he was unable to speak more than a word or two so that explains things to me. I believe the first testing is actually representative of abilities. And I used this lesson as caution for him and anyone else that even in the hands of an extremely experienced tester, it's possible to get results that don't represent the child if the tester just doesn't "get" your child.
But, I still think it's funny that performance went up as IQ went down.
But if the evidence shows that the IQ number is unreliable (as I think it does)-- then the inverse relationship between performance and IQ isn't real anyhow.
With that kind of behavior during the test, I'd be dubious about the accuracy. Especially if it contradicts your gut feeling.
