How many people (in absolute and relative terms) from each cohort passed/failed the training program and how long did they take to do so? Did the numbers change with the two policy changes described in the article?

If there was no change (or an increase) in the absolute numbers of passing graduates, that would support what you're saying. If there was a drop in the absolute numbers, it implies that there's at the very least fewer competent controllers. (And changes in the relative numbers tell us about whether the efficiency of the program changed.)

Given the litigation and FOIA requests around this, it seems like this data should be floating around, and should be fairly conclusive for one side.
