Hi MumofThree,
Here's one of the articles I had found through a thread here from 09:
http://www.thefreelibrary.com/Gifted+and+highly+gifted+students:+how+do+they+score+on+the+SB5?-a0150850213

And that thread:
http://giftedissues.davidsongifted....6335/Gifted_and_HG_how_do_they_scor.html

I started running across a few different ones. I'll see if I can find those.
