An empirical assessment of commercial web-based professor evaluation services

We examined the validity of data found on a popular web-based, user-created commercial professor evaluation service, RateMyProfessors.com (RMP), in business school settings. We compared publicly available RMP data for two business schools with official faculty evaluations unavailable to the public. We find that students rate professors significantly lower on RMP than on official university evaluations. However, we also find that the rankings of official university evaluations and RMP are significantly correlated (p < .001), with correlation values high enough to provide useful data to students.
