I don't know, but I've seen them say here that sat & act means more to school teachers and principals than iq tests because it's in a format they understand. I thought the scat was for younger kids so I googled it and it's for grades 2-6, used by CTY, and only $55. But I don't know much about testing so hopefully someone else will answer.
