Thanks, Snowgirl and Kriston. Your insights are very helpful. I am in a similar situation as snowgirl in that the FSIQ score would not qualify DD6 for some selective programs (ie. Young Scholars and a program in our area for those scoring in 99.9%) but her GAI would. The discrepancy between VCI and and working memory was 34 pts and between PRI and processing speed was 32 pts. And, like Kriston's son, I see where she could be viewed as a dawdler.
I guess the scores are helpful in terms of being aware of how memory and speed may hinder her ability to work on material quickly. It is relevant for making sure that teachers don't apply this inability to judgments about cognitive capabilities. I plan to apply to the young scholars program (her VCI missed by 1 pt) and hope that they consider the GAI as well.
