Strictly speaking, his only achievement score below solidly Average is in math fluency, which is at the border of Average and Below Average. All other scores are in the mid-to-high reaches of the Average range, with untimed basic decoding/encoding (reading/spelling) skills among his personal strengths, and the remainder in the middle of the range. (Math calculation is a composite of calculation and math fluency.)
Hard to say what exactly his cognitive results mean, given the Dx and the high degree of variability between subtests within the VCI, FRI, and WMI. One could speculate that his verbal reasoning reaches into the MG range, especially when in familiar, contextualized language, but his actual score, of course, is more high average. His quantitative reasoning skills present as essentially age-appropriate (consistent with his math achievement) while his adaptive reasoning presents as extremely low. This may because he genuinely has challenges with abstraction, shifting, and/or flexible thinking, or it may be because he was impulsive or inattentive on this multiple choice task, or it may be due to some other factor. He did a whole lot better on the visual working memory task than on the auditory task. Was there any indication that there were differences within digit span's three conditions (forward, backward, sequential)? Sometimes that can lead to hypotheses. Picture span also uses concrete-familiar images, which can be easier for some children to encode into short-term memory than meaningless symbols (numbers).
The data are still consistent with OT support (though you would need the OT eval/progress data to say so more definitively). And writing from a physical stand point. IRL, I wouldn't be surprised if he fatigues, or finds it to be too physically burdensome to generate written output, even when he has the language expression skills. Or just gets frustrated with his own pace.
