Did the psych give any kind of qualitative estimates of ability? Or indicate which domains were most noticeably affected by lack of effort and inattention/impulsivity? It is likely that, once the ADHD is addressed, future testing will be substantially higher, especially in some areas, such as those with multiple choice answers (MR, FW, VP), high short-term memory demands (Ar, DS, PS, CD), and those most sensitive to sustained attention (SS, CD). In my experience, the verbal subtests are a little easier to manage in cases of poor effort and attention, as one has to generate an actual response, and the examiner is allowed to query responses, including those with questionable effort. That's probably why those are his highest scores.
