Fairly interesting rankings from the Center for College Affordability & Productivity (CCAP), a two-year-old research organization in Washington, D.C. with a free-market bent. ("We evaluate colleges on results. Do students like their courses? How successful are they once they graduate? In short, we review the meal.")
Rankings are based on:
1. Student evaluations posted on Ratemyprofessors.com (a nine-year-old site with 6.8 million student-generated evaluations)
2. College graduation rates
3. Percent of students winning awards like Rhodes Scholarships and undergraduate Fulbright travel grants
4. Vocational success using Who's Who in America ("Though imperfect, it is the only comprehensive listing of professional achievement that includes undergraduate affiliations")
Their rankings:
1. Harvard
2. Yale
3. Princeton
4. University of Chicago
5. Brown
6. Columbia
7. Cal Tech
8. Stanford
9. Northwestern
10. Dartmouth
They also rank National Public Universities and Liberal Art Colleges.
