Playboy's Top 10 Party Schools

April 15, 2011— -- Playboy has declared the University of Colorado at Boulder the No. 1 party school in America, citing "reefer madness," the town's four breweries and several local distractions that tempt the school's students. It is followed by Penn State University and Arizona State University, which rank second and third respectively.

According to Playboy, the rankings are determined via Playboy on-campus Facebook pages, surveys and other interviews with students. They consider the male to female ratio, the winning percentage of sports teams, vicinity to beaches and ski slopes, and the music scene.

The University of Colorado's ranking was in part due to its vicinity to medical marijuana dispensaries and the annual turnout of about 24,000 undergrads to an April 20th smoke-out on school grounds.

"Literally dozens of world-class ski resorts are a drive away," Playboy said on its website. "You know Boulder is a party school because whenever you tell someone that you went there, the first thing they ask is, 'Did you graduate?'"

"I think most people are excited and proud of [ranking No. 1 party school] and I don't think it will affect job opportunities at all," said Amanda Presley, 22, a senior at the University of Colorado at Boulder.

"The people that go here work really hard at school," Presley said. "It's a very difficult school...and we just like to party hard too."

The University of Colorado at Boulder says they don't take this ranking seriously.

"It's a joke rating," said Bronson Hilliard, a spokesman for the university. "It's not meaningful, it doens't measure anything important...it measures perception and it's unfortunate."

"The impression that our students here are doing nothing but partying here is overwrought," Hilliard said.

Arizona State has made its mark on the party list before. Last year they were ranked No. 6. With a student population of about 70,000 and warm desert climate, Playboy points to ASU's tendency to shed clothing to their No. 3 ranking.
