I don't think this is a girl being overlooked, I think this is using a non-verbal test to try to measure a child who may have verbal rather than non-verbal strengths. Your son clearly has non-verbal/perceptual strengths and is relatively weaker in verbal domains (PRI 7 points higher than GAI). It might be worth it for your daughter to get outside testing using the WISC-IV to see if her VCI and/or GAI would qualify her.
