My son tested this year in 3rd. I kept it very low stress, and even with his AS, he went in and did amazingly well behavior and nerves-wise. My personal idea is that he has trouble with experiences he isn't used to, and so many of these talent searches ask for similar tests, that I want him to get used to the experience of it. Imagine my surprise when he was fine with it!

I have no idea how well he did, but I am very happy with the experience overall.:)
