Still, I did the same thing you do, by reading the book 'Genius Denied' by the Davidsons. I saw what the other kids were doing, and thought 'Well, at least we don't have to worry about that, my son doesn't do what those kids do.' About a year later we had test results and I was filling out my YSP application. Apparently those IQ testers jobs are secure.
Grinity, I did exactly the same thing! Genius Denied has description of unbelievably smart kids, so not DS5. Well, here we are, the kid is DYS. May be that's why the IQ tests took me by such a surprise.
