It 19th of the 171 public universities rated. Ivy League schools are not public institutions. Of all universities UCONN ranked 57.
I think what you're referring to is the Washington Monthly rankings for colleges that has some loose "contributions to public good" description wrapped around all the many components it refers to such as Bachelor's to PhD and Students receiving Pell Grants categories. The linked table for universities does not have UConn very high at #81 overall, but I think the category you're talking about is the "Community service participation and hours served" column where UConn has its highest rating at #9.There was once a special kind of ranking done for universities in which the overall assessment was based on positive contributions to society. Schools good at certain kinds of engineering might be ranked high because of their particular innovations; producing a successful teacher might have been ranked as high as producing a successful lawyer; providing upward mobility to graduates ranked higher than churning out upper class kids; etc. I liked that much better than the USN&BR criteria. Of course, with my typical lack of foresight I never bothered to remember who did those rankings or even if they still exist. I only knew about it at the time because there was only one Ivy League school that was in the top ten: Cornell. I don't know where UConn ranked at the time, but with it's top ratings in sustainability and being green I'm guessing it might be top ten now as well. Though I am glad that UConn is 19 in the ranking that gathers all the attention.
In my opinion, UCONN is legitimately counted as a top university because of its RU/VH achievement.
And conferences like the Big10 and ACC when evaluating any additions.Whatever the various ratings the US News and Business Report rating is one most Americans are familiar with. UCONN's steady rise and position can only help in the process of perceived value among recruits.
