Unless you have a recommendation from someone, I don't know. I went to a guy who on his website specializes in GT kids. He administed the WISCIV. He has several calculation errors which I found and Dottie found, which would keep him from DYS (assuming he would make the cut on WJIII) but he doesn't have time to find his mistake and re-write the report. So I never got a final report. That was over a year ago and many, many phone calls.
