The psych may also consider re-testing with the WISC-V, instead of the SBV, as it does have a Quantitative Reasoning Index, separate from the Fluid Reasoning and Visual Spatial Indices.
And some ADHD kids do have high PSI on rote-type tasks, where being a little impulsive doesn't hurt you too much, and may actually make you faster. Especially if they are conscious of being timed. It's one of the reasons that extended time accommodations can be a double-edged sword for kids with ADHD. It's part of the hyperfocusing, which many ADHD persons can do for short periods of time. (Remember, ADHD doesn't mean difficulty attending, it means difficulty -regulating- attention, which can cut both ways.)
