Thanks for all the replies! I will for sure ask him about the score when we do our appt. He was recommended to me as an expert in these tests, but even experts make mistakes now and then. He did an excellent job of making her comfortable, and I was very worried about that. So I am still happy with him.
Honestly, I would not be disappointed to lower her score out of the PG range. Raising a PG child to their potential seems a daunting (though rewarding!) task. Based off my research, I expected her results to be in either the highly or exceptionally gifted range. I had to sit down when I read the results, LOL.
The only thing I still wonder about is that shortly after the test she was sick with the stomach flu. Do you think that would affect her results? She started telling me her stomach hurt on the way home.

Its a bummer to pay all that money and wonder about the accuracy.
I will try to post back after I talk with him. I still think that her scores (if needing correction) will be a useful support while discussing accommodations with her school.
Thanks again everyone!
