<p>DON'T BLAME USNEWS, BLAME THE COLLEGES THEMSELVES....</p>
<p>USNews gets its numbers directly from the colleges themselves. Often, schools have reported one number to USNews, and another to government agencies or bond rating agencies.</p>
<p>The whole "class size", "faculty resources" etc categories are often subject to accounting manipulation - not necessarily because some one is trying to con USNews, but simply because accountants can differ. What formula should be used to allocate administrative overhead, etc to the undergradute vs the graduate school aspect of a university? There is no magic rule. What constitutes a "class"? How are seminars, grad student classes, tutorials, sections etc. treated? Despite USNews efforts to encourage uniform reporting (ie, the Common Data Set, etc) there is no "official" formula and reporting differes from school to school.</p>
<p>Every stat can be "manipulated" if you are determined to do it. Certain schools do not include the SAT scores of certain "affirmative" action admits. They do this by developing a "policy" to exclude the scores for people in "special programs", or invite them to start early with a two-week "enrichment" or "headstart" program in August, so that they are technically not part of the class starting in September, etc etc. </p>
<p>Moreover, many schools report SAT scores only for a minor fraction of admits by making them "optional". Those submitting them anyway, naturally, tend to be those with higher scores, and the schools are happy to report these numbers to USNews.</p>
<p>Then there is the category of "percentage of matriculants in the top 10% of their class" - a stat USNews has always set great store by. I invite you to check the fine print (the famous "footnote 5") in the USNews rankings and see which schools report this stat for a minor fraction of the matriculating class. Some of those whose reported data is based on less than 51% of the class might surprise you - including Princeton, Yale, Dartmouth and Brown.</p>
<p>Then there is the case of the California schools who report that a ridiculously high fraction of the freshman class were in the "top 10%" of their class, despite SAT medians that seem at odds with such a claim. The reason, of course, is that admission is often based entirely on this stat, regardless of the quality of the local school. </p>
<p>This technique was developed (in California, Texas and Florida) to get around affirmative action bans. Nevertheless, it earns those schools "selectivity" points under the USNews formula. Some cynics have claimed that, as a consequence, 40% of the class is included in the "top 10%" in some California school districts. Don't want to "deprive people of an educational opportunity", you know!</p>
<p>Then, I hate to destroy the faith of posters like "thethoughtprocess", but other stats like the "admission rate" are also subject to substantial manipulation - directly and indirectly. Some schools include as "applicants" people who never completed their application, or withrew it before it was acted upon. Some very fine schools use this technique for puffing up the number of applicants - and I am not talking about WUStL, which famously counted as applicants people who did little more than respond to a brochure inviting people to retun a postage pre-paid card as a request for information. Waitlist admits are canvassed in advance by some schools to ascertain their willingness to accept a place "if offered." Thus such schools can boost their yield (and drop their admit rate" by "going light" on RD admits and filling in with those juicy "100% yield" waitlist admits.</p>
<p>And finally it must be recognized that the "admit rate" is manipulated to a substantial degree by schools which fill a large fraction of the class via binding ED. If you fill half the class with those juicy "100% yield" ED admits, then you cover up what is often a much lower RD yield rate when you compete on the "open market."</p>
<p>Take #1 Princeton: it fills half the class via binding ED, but in recent years has convinced only half the RD admits to enroll (52% for the Class of 2009). Can you imagine how it impacts your admit rate when your yield is 50% vs 100%? At 50%, you have to admit 2 people to fill every seat, and the "admit rate" rises accordingly. And there are schools where the effect of binding ED on overall yield - and, in consequence, the "admit rate" - is even more dramatic.</p>
