RateMyProfessors.com (RMP) is a review site, founded in May 1999 by John Swapceinski, a software engineer from Menlo Park, California, which allows college and university students to anonymously assign ratings to professors of American, Canadian, and British institutions. The site contains more than six million ratings, for more than half a million professors. The site was originally launched as TeacherRatings.com and converted to RateMyProfessors in 2001.
All ratings are supposed to be anonymous without any instructor input or decisions. According to the site's privacy policy, RateMyProfessors.com will only reveal a user's personal information in response to a court order or a subpoena.
In November 2005, RateMyProfessors was sold to Patrick Nagle and William DeSantis. The site was sold again in January 2007 this time to MTVu, a subsidiary of Viacom.
