Thanks! I certainly don't want to alienate the tester; so I have wondered how to approach this conversation. I left a message for her, and I guess I will simply ask her what subtests she was planning on using. Depending on her answer, I might simply state that we want a more complete picture.
I am pretty sure my DD's overall score will not be DYS high, but I think there is a possibility she could be in the verbal area. If she were in that rank, then it would be good to have the option to apply, hence the extended scores question.
In any case, one of the things I am most interested about is how asynchrony development is playing in some behavioral issues we are seeing at home. I think there is a signficant dissonance between where she is at in terms of reading/writing and math. I hope that achievement testing will help us understand that better.
I really appeciate your comments. I am glad in your case, DS scored high enough that the GAI and the extended norms did not matter.
I know the psychologist frequently tests kids for admissions to the gifted schools in our area. I know that the schools are not that interested in processing speed. So, for instance, all of the local testers are used to calculating WPPSI scores with and without coding. I am extrapolating from that, that it will be standard procedure to calculate GAI.
