For those of who have kids who aspire to high end college educations, there is a need to identify the institutions best able to deliver those educations. Perhaps not to the 0.01% precision level (A is just a touch better than B), but somehow, we need to make such identifications.
I suppose that one way to do so would be to closely examine a big chunk of data about Harvard (what they self-publish, plus other sources), take a tour of the campus, interview students and alumni, and then repeat the process for the local flagship U, and see which is better.
But wait, you say, that’s a silly strawman. Everybody knows Harvard is way better than the local flagship U.
Yes, they do. But how do they know that? Because the collective culture has absorbed many many individual data points over the years and come to the (reasonable) conclusion that Harvard is a lot better (in the academic sense), than the local flagship U. But are those collective culture data points any more accurate than a statistical methodology such as USN implements?
It doesn’t matter too much when making course comparisons between schools that either approach would widely separate (Harvard vs. flagship U.). But what about finer grained comparisons? Harvard vs. Penn vs. Hopkins vs. Emory vs. Northeastern?
Even if many of us know, in some general sense, that Harvard is the best of those 5, and the best or pretty close to it nationally, relatively few (especially OUTSIDE of the CC universe), have a great intuitive feel for, say, Hopkins vs. Emory.
I view the USN list as a useful way to form my own lists for our family. We will not visit or research all 3000 or whatever universities that there are in the US. We won’t even do it for the 200 or so that make USN’s main ranking list. But given our geographic location, and a broad set of other criteria of interest, we will likely pick some number from that USN list (and other lists, perhaps, and other sources such as counselor recommendations, college fairs, and the like), for further research, and perhaps visits.
And at some point, as our lists tighten up, we’ll want a sense of which schools are likely reaches, and which schools would likely carry greater academic weight, and yes, prestige, which can matter in various ways post-college. USN’s list is not perfect, but it’s a reasonable shorthand for all this stuff.
