<p>US News stopped using "yield" (percentage of accepted applicants who actually enroll) in its rankings some years ago. But doesn't yield tell us something, quite apart from selectivity? Selectivity focuses on one half of a market transaction: how likely is it that an applicant will get an offer from a school? Yield focuses on the other half: how likely is an applicant actually to accept the school's offer?</p>
<p>Many factors go into a decision to accept an offer of admission, of course: perceived academic quality, prestige, perceived quality of life, expected cost (net of financial aid), and "fit" factors unique to the individual applicant, all measured against the alternatives available to the applicant. </p>
<p>But schools' yield ratios vary enormously, from nearly 80% at Harvard to around 20% at Case Western and some of the second-tier UCs (using as our universe only US News top 50-ranked national universities, for the moment. This suggests that yield can tell us something about a school's perceived desirability within its applicant pool. Almost no one says "no" to Harvard, and not surprisingly, HYPSM--or rather HYSMP, in that order---lead the yield chart. These are clearly "destination schools": if accepted, you'll likely attend.</p>
<p>But other schools attract a large and highly competitive applicant pool, yet find relatively few takers when they actually offer admission. This suggests that most of their applicants view the school as less desirable than its competitors (all things considered), and that many are using it primarily as a "backup" (I won't say "safety") in hopes of doing better.</p>
<p>Below are the yield ratios of the national universities ranked in the top 50 by US News. There are some surprises here: apart from the very top (HYSMP), yield ratios do not track US News rankings very closely. Some schools appear to be "destination schools," highly desirable to their applicant pool even if their applicant pool is not as strong as some other schools'. The University of Florida (#7), Notre Dame (#9), UNC Chapel Hill (#11), UT Austin (#12), and UVA (#13) are obvious examples. Some other public flagships--U Washington, UIUC, Michigan, Georgia Tech, and Wisconsin-Madison also rank fairly high as "destination schools", right around the same level as Cornell and Duke. Some elite privates---CalTech, Chicago, Rice, WUSTL, Northwestern, Johns Hopkins, Tufts, Lehigh, Emory---rank surprisingly low on this metric; despite their large applicant pools, stringent admission standards, high selectivity, and elite reputations, roughly two out of three applicants offered admission at these schools decide to go elsewhere, again suggesting that many applicants are simply using them as "backups," hoping to do better.</p>
