I think the tester is on the warpath to diagnose something, and calling a 13 a weakness (possibly indicating a disability) is quite a stretch. My oldest is SN and you would be horrified if you could see what we have experienced, mainly test results which are widely different from each other (by different testers), each with its own conclusion which appears tailor made to the agency which did the eval. Depending on the agency or school district, within a period of 1 year, my ds had IQ scores varying by 40 points. It honestly sounds to me like they want some sort of diagnosis and maybe they hoped the comprehension score would be lower? Also that business about the OT saying he does not read facial expressions, that sounds highly subjective to me. In my experience OTs have been some of the worst at "creative diagnosis" if you know what I mean. GL to you. You have one very bright child there, and that is the only conclusion I would carry away from that test session and those high scores.
