<p>All of these universities contribute in some way to the “public good”, so in that sense the ranking is not totally inaccurate - they’re all “good.” </p>
<p>However, in addition to being inaccurate in all other respects, the ranking penalizes schools that focus “too much” on education, e.g., by having “too many” professors and not enough students. It rewards places that are basically diploma mills and penalizes those that have low student to faculty ratios, such as Caltech. </p>
<p>It also penalizes schools that happen to have a larger proportion of their classes from wealthier areas of the United States (e.g., Long Island), but that’s wrong IMHO because obviously wealthier students are statistically more likely to be prepared for top colleges and therefore are likely to concentrate at the best schools, in part so they can go to the best graduate schools afterwards but also because they want to meet other smart people like themselves (from all different backgrounds). It’s kind of like penalizing restaurants for attracting the best chefs rather than hiring chefs who have names starting with each letter of the alphabet. If they want to measure socioeconomic diversity, they’ve taken the wrong approach. Schools that attract a lot of students with Pell Grants also often attract a lot of students who got in because they could pay, and also, not all students on Pell Grants are necessarily representing the lowest income groups out there. Also, diversity “on paper” means absolutely nothing. Just because you have 30% of students on Pell Grants doesn’t mean those 30% actually interact with the other 70% of (rich) students! A school with a lower % of students on Pells, but that actually has frequent, meaningful interaction between those students and the others, is more diverse in my book.</p>
<p>Finally, the ranking penalizes schools that attract students with very high SAT scores. It also rewards schools that have high ROTC participation, which is a pretty random, lame measure of postgraduate “citizenship” if you ask me. There are many other ways that smart, motivated college graduates can contribute to the future of our country, e.g., through Teach for America, Americorps, entrepreneurship, to name just a few.</p>
<p>Those are a few reasons why it is worthless.</p>
<p>Of course, the USNWR rankings are highly questionable as well, for various reasons. However, even though some of the data that they collect is completely flawed, on an overall basis the rankings are at least accurate to within 10 or 20 places.</p>
