Interesting read. However, testing for "how many still devoted significant time and energy to Torah learning? How many reported being in stable marriages? How many were still frum?", I don't think is a direct test for yeshivah competence, as the families and other factors that have nothing to do with the learning contribute heavily to those results.
That's true for data from a single school. But if there's enough data covering enough institutions (or longitudinal data covering many years where there were policy changes), we can control for externalities (like family influence and income) and accurately identify trends.
The trick would be getting mosdos to agree to actually collect and release such data.
