Maybe I'm missing something, but it seems that you could get at the information you want to get at by plotting a bell (or near-bell) curve. Then, it would be pretty easy to see which schools are how many standard deviations away from the average school, as to employment rate. That would be a ranking, of sorts, but it would solve the problem of misleading ordinal ranking.

By definition, Z scores are standardized variations from the average. But is a 0.1 difference in Z score necessarily material? Some statisticians suggest that even a 1.0 difference in Z scores is not necessarily material. These statisticians suggest looking for a 2.0 difference.

In terms of the data discussed above, when the average is a 56.9% employment rate, a Z score of 0.0 tells many potential students that they ought to look elsewhere, especially when entry-level compensation is falling.
