I'm not a testing expert. I'm surprised that they reported a FSIQ given his huge discrepancies. I'm not even sure if GAI is reflective of his abilities given the huge gap between the VCI and PRI. I would assume that he has issues with output and that low processing speed is a major road block for him.

Could you give more info re his executive function challenges and the issues at PE? It might help people give more specific recommendations re accommodations.
