Just got results back from the WIAT III for my 10 year old. Actual WIAT scores are all significantly different than predicted WIAT (based on FSIQ of 152). Actual Total Achievement score on WIAT was 158 but the predicted score was 139 based on the WISC scores (difference of -19).
I can find lots of information (suggesting learning disabilities) when there is a significant difference between wiat and wisc the other way around (performance lower than iq) but nothing that would help us figure out why such a discrepancy the other way? Is this normal in gifted kids?
