I think they have just opened a can of worms. My dd's scores went up for the PRI score by 6 IQ points and her FSIQ went up by 3 points. However, All it still tells me is that she is in the >99.9%. I already knew that.

Also, when my dd was tested the psychologist stopped when my dd "had gone far enough and had already hit the subtest ceiling". If these new score norms had been available she would have gone further.

I guess I just don't feel I have gained any more information.
