You’ve heard it before, and you’ll hear it again. And again.

Forbes released today its rankings for America’s Top Colleges, Most Entrepreneurial Colleges and All-Star Student Entrepreneurs, and it comes as no surprise that Massachusetts’ colleges are included in all three of Forbes’ lists.

Out of the 650 colleges included in the rankings, Williams College came in as the second best college, with Harvard, MIT, Amherst College and Wellesley as 6th, 11th, 13th and 16th, respectively. Princeton University topped the list.

Exclusive to Forbes by the Center for College Affordability and Productivity, the rankings “focus on the things that matter the most to students: quality of teaching, great career prospects, high graduation rates and low-levels of debt,” according to Forbes. “They do not attempt to assess a school’s reputation, nor are they a measure of academic selectivity and we pointedly ignore any metrics that would encourage schools to engage in wasteful spending.”

More specifically, the rankings are based on five general categories: post-graduate success, student satisfaction, debt, four-year graduation rate and competitive awards. See the rankings’ complete methodology here.

As for the most entrepreneurial colleges, MIT ranked No. 2, with 25,600 active alumni-founded companies employing 3.3. million people, as of 2006. Harvard came in at a close third, largely thanks to its 10 self-made billionaires, including Steve Ballmer (’77), Phil Falcone (’84) and Sumner Redstone (’44).

Babson College made it to the list at No. 12 and is called the “entrepreneurial powerhouse.”

Three more colleges from Massachusetts rounded out the list, with Amherst College at No. 18, Williams College at No. 19 and Hampshire College at No. 20. That’s right — out of the nation’s 20 most entrepreneurial colleges, six were from Massachusetts.

And finally, Her Campus co-founder and Harvard senior Annie Wang earned a coveted spot as one of just nine Forbes All-Star Student Entrepreneurs. Founded by Harvard undergraduates, Her Campus is the top online community for college women. In March 2009, Her Campus won the i3 Innovation Challenge, Harvard College’s business plan competition, and then launched in September that same year.

Since then, the site has formed “content partnerships with Seventeen magazine, SELF magazine, Glam.com, USA Today and The Huffington Post and worked with clients including Victoria’s Secret PINK, Ann Taylor LOFT, New Balance, popchips, Pinkberry and Intel.”
