Honestly--IQ stuff makes my eyes cross. I'm much more oriented to the "so what." It looks like the "so what" is to take results with grain of salt. I'm most interested in seeing the individual scores and his PSI--which was much lower 30+ points than GAI last time--and evidently can be useful info? So confusing!
Very simply put, when Full Scale IQ (FSIQ) is believed to be impacted by a low working memory and/or slow processing speed, a General Ability Index (GAI) is calculated. The score discrepancy can be indicative of 2e, leading to prescribed remediation, instructional differences via an Individualized Education Program (IEP) and/or accommodations (504).
