One thing that really surprised me was how she was after the test. I fully expected her to be frustrated and exhausted after two hours of testing--as she sometimes gets after a few minutes of homework--but instead she came out looking happier and more stimulated than I have seen her in quite some time. She stayed that way the rest of the day and asked when she could go back and do more. That to me was the most telling sign that we need to get her into a more stimulating environment.
This was my DD 8.5, too!! She said that the WISC was the most fun she has ever had. She has asked numerous times when she will be able to go back and do it again! She participated in a research study a few months ago and they did some subtests/achievement tests (a study of ADHD), mostly the times ones. After the tests she could earn money by 'learning' computer games and advancing. She was gone a LONG time and came out with a fistful of $5 bills and a frazzle and dazed looking grad student. DD's face was flushed and she was more excited that I have ever seen her. She was in her glory.
