I'm curious about the mention of extended norms. According to the technical bulletin (which I've seen before), my child qualifies but didn't have them calculated. It doesn't really matter for us. However, it seems like relatively few people use the extended norms and that qualifying scores are often raised higher when they are used.
Have all of you found them to be useful?
My dd had 2 19s, and after I inquired about extended norms, it raised her PRI from 143 to 149, her FSIQ from 138 to 140, and her GAI from to 142 to 146. In the end, the new scores were really not useful.
