I talked to Dr. Lusby a couple of months ago and she sounded great and very knowlegable about giftedness but very expensive for testing. I have talked to Tandra Wood at UNT and she charges $300 (which is the university's cost for the IQ/achievement testing materials). She will also include a written report at no charge since she performs test for grant/research projects so she can't make a profit. Tandra said she is one of the top IQ testers for this region for DYS. I also left a message for CATS but never got a call back.....I think their main focus is testing for the private schools.
