UNDATED (AP) -- Princeton tops the latest U.S. News & World Report college rankings. It's the eighth straight year the New Jersey school has either tied or held the top slot outright.
Just like last year, Princeton was followed by Harvard and Yale in the rankings.
As usual, a few schools moved up or down a slot, but there were no major changes. Stanford is number four, followed by Cal Tech and the University of Pennsylvania, which tied for fifth.
Williams and Amherst are the highest-ranked liberal arts colleges.
The formula for the rankings includes variables such as graduation and retention rates, faculty and financial resources, and the percentage of alumni donating money to their alma mater.
The magazine has responded to one complaint about the rankings: that they punish schools for enrolling low-income students. For the first time, U.S. News is factoring the percentage of students receiving Pell Grants into its calculation of a school's "graduation rate performance."
The top 10 national universities were:
1. Princeton University
2. Harvard University
3. Yale University
4. Stanford University
5. California Institute of Technology
University of Pennsylvania (tie)
7. Massachusetts Institute of Technology
8. Duke University
9. Columbia University
University of Chicago (tie)
