They went ahead and did the WISC today and Dottie was right, the Slossen turned out to be an overestimation of her abilities... or something else is going on.
The ed.psych said her FSIQ was 109 and she'd get the formal report to her later next week. The psych had extreme concerns about ADHD and said that the girl was extremely distractable, unable to refocus even with short breaks and overall was like a textbook ADHD child. She was surprised to hear that her achievement was so high and said that she must be coping very well at school to be able to get by.
This just added to the mystery of how to best educate my friend's child. They're happy they did the private testing and feel like they got really good information but are stuck in a "now what?" kind of scenario. A kid who achieves like a HG kid but doesn't test that way doesn't get a whole lot of service at school. They may go ahead and pursue the ADHD label with the school or not... they don't know yet.
