Anyway, the nice thing about the WISC, I think, is that it's shorter than the SB-V by a lot--like 2 hours shorter for us.
It must have something to do with the tester. My dd took the SB (when she was 5yo) and was finished in just a little over an hour. I think the tester can choose where to start the questions so the child does not have to spend an inordinate amount of time on easy questions. This is where it is beneficial to have your testing done by someone who regularly works with gifted children. Dottie can correct me if I am wrong.
