So actually, the WASI-II results are nearly identical to the previous administration on the PRI. It's the VCI that has gone up a bit. The main set of scores that is different is your previous neuropsych (WISC-V). Based on what you've provided, I agree about the possible impact of time limits and attentional dysregulation on her 2019 WISC. We also have to qualify the 2019 WASI scores by noting that there may have been a tiny bit of score inflation on that PRI due to practice effects (the items are not identical, but the novelty of the tasks themselves would have been lost). Another factor is what she said about herself this time around, which is that a WISC is substantially longer than a WASI. That WISC likely took at least an hour and a half, possibly longer (especially if she attempted a lot of block designs), vs 30-40 minutes for the WASI.
IOW, for the upcoming neuropsych, they need to be aware that she fatigues quickly, and may need more frequent breaks.
To be fair, she probably didn't literally take an entire day on recent testing (unless she needed a lot of breaks, which is possible), based only on the WASI and the core WJ subtests. With her fluency scores (which are age-appropriate or above), the WJ shouldn't have taken more than about two hours or so (all told, no more than about three hours of testing between the two tests). But yes, it is still tiring to do one's entire cognitive and achievement testing in the same day.
As to the results, taking into account regression to the mean, her achievement scores generally are not unreasonable given her current and past cognitive measures. Reasoning (strong) has historically been much stronger than efficiency (age-appropriate), and nonverbal reasoning stronger than verbal reasoning, and that's how the academic measures come out.
The average scores are all ones that are affected by automaticity skills (MF & SWF, and their multi-step analogs Calc & WS). The VCI would predict language-based skills in the 120s, and that's where they fall in reading. The PRI would predict math skills in the 130s, and that is likewise where they are in reasoning.
The only skills that are consistently below personal expectations are her written expression skills, which are probably affected by the automaticity and organization vulnerabilities that are often associated with her existing diagnosis (although I would still want to keep a close eye on the possibility of an additional learning challenge in writing). If your neuropsych wants to take a closer look at writing (e.g., a TOWL-4, PAL-2 or similar), it might not be a bad idea.
