I have been reading through the forums and also online about the FSIQ and GAI. From what I've read it seems like the GAI typically winds up being several points higher than the FSIQ. My ds has the opposite results and I can't seem to find anything about why that might be or how to interpret the score. Something that has been mentioned is a possible LD.

His FSIQ is 146, his GAI is 135.

Can anyone clarify or direct me to a reference that can explain what this might mean? The tester had no information, just explained why they calculated the GAI, and we're not sure where to go next.

Thanks!
