Also, just because you are very interested in rankings (and you can verify these for accuracy because I’m going off memory . . .), on the liberal arts side of things Bard - which is an excellent school in NY state, went from something like 35 to currently 49. Why? Because other LAC’s have aggressively decided to climb the ladder. And my oldest’s art school Pratt Institute in Brooklyn (a relatively specialized curriculum) went from #10 - Regional Universities (North) a few years ago to “Unranked” today. Ironically, it’s a far more selective and promising institution now than it was just five years ago. Pratt has been well known as a nationally-ranked art/design school for decades now, and ‘losing’ a USNews ranking has no impact (since it’s clientele - i.e. design students and their families - use other criteria than USNews to judge this kind of specialized school).
There’s enough diversity among hospital systems to draw a better comparison to specialized colleges than to large universities. As I mentioned prior, you really can’t compare UChicago Hospitals to Mayo and not just because the south side of Chicago isn’t Rochester MN. The two are very different systems, even if both were picked up and re-planted in the same corn field.
