I had to request the wisc cover sheet repeatedly for my ds6, and wondered along the way why I was bothering, since his score already qualified him for the program we wanted and dys. When I had it rescored with the extended norms, though, the fsiq went up 14 points. So I guess I agree that it can help you the parent better appreciate what life might be like for your child. I also agree that it may help to provide a "wow!" factor in the event that it is needed for advocacy for your child.
