Hi and thanks so much for the response and the welcome. I'm thrilled to have found this place.
In answer to your question, our tester said she was unable to calculate the GAI as there was no table/chart that went below 100. Then I found this place and noticed some here looked like they were able to get GAI's with lower scores. So I thought perhaps it was possible to calculate it but that it wasn't and "official" score. I'm hoping if I submit her test results that Davidson will look at the subtests and not just the FSIQ. Keep your fingers crossed for us.
