I think this is an interesting list, but I think it measures something different from what I mean by “prestigiosity” (which I would say is the perception of prestige among people like those who congregate on CC). Maybe “desireability?” It is notable, though, that the list isn’t all that different from mine, or from the USNews list. I think it shows, perhaps, that some of the leading LACs may have less desirability than their perceived level of prestige.
OP, you’ll know you have a good ranking system when people start to post that Berkeley is rated too low.
