Not expert in testing, but I would be curious to see what his score would be using the extended norms. It might bump the PRI score. Also, the picture concept score seems off to me. Someone might know this better than me, but could there be a possible vision issue? Fantastic working memory!
I mentioned uppost that picture concepts has significant verbal loading on it, and may reflect his average verbal reasoning, in this case. Vision issues should have affected block design as well.
With only one 19, and an index score only in the 130s, the extended norms are not indicated, and probably would not raise the PRI enough to hit DYS-level anyway. I agree that the PRI is probably a low estimate, though, and would think about re-testing in two years.
