Dottie, I have no idea how to figure scores aside from the GAI so I'll have to take your word on the VCI. I thought her scores jumped quite a bit as well. I will have the tester double check his numbers. The report he gave me was just preliminary numbers, not a full report. Maybe there was an error in his calculations? As far as the substitutions. He said "Giving the additional subtests is justified since there is a large discrepancy in her scores (the original ones I assume). Again, I'm just going off what he said.
