RateMyProfessors.com is the largest online destination for professor ratings. With 8,000+ schools and over 15,000,000 entirely student-generated comments and ratings, RateMyProfessors.com is the highest trafficked free site for quickly researching and rating 1,800,000+ professors from colleges and universities across the United States, Canada, and the United Kingdom.
Each year, RateMyProfessors.com compiles Top Lists of the Highest Rated Professors, Hottest Professors, and Top Schools in the U.S. based on ratings from students.
The site uses a five-point Likert scale as well as a binary scoring system for students to rate professors. Below is a summary of the overall methodology used to compile the 2012-2013 rankings as well as notations for each of the categories*.
Professors are ranked according to the following methodology: Each professor’s rating is first standardized and the standardized ratings for the past three years are weighted, putting more weight on recent years and less weight on ratings from the past (15% weight for 2011, 25% weight for 2012, and 60% weight for 2013). Using the weighted score, professors are ranked from high to low. In order to provide statistically reliable trends, only professors with 30 ratings or more are included. Ties among professors with the same weighted score are broken via their total number of ratings; that is, for two professors with the same weighted score, the one who receives a larger number of ratings is ranked higher.
It should also be noted that school size does not affect the outcome of the lists nor does it give professors from larger schools an advantage over their corollaries from smaller schools. We performed a regression analysis on school size vs. number of ratings and found no noteworthy correlation between the two.
Here now is a look at how each of the lists are compiled:
Highest Rated Professors
Students rate professors on several dimensions: Clarity, Helpfulness, Easiness and rater interest (interest level prior to attending the class). However, a professor’s Overall Quality rating (which informs the highest rated professor list) is determined by an equal weighting of only two criteria: clarity and helpfulness. 5 is the highest rating and 1 is the lowest rating for each of the above-mentioned dimensions.
A professor who receives a chili pepper is considered “hot.” Chili peppers are awarded based on the sum of positive and negative (hot or not) ratings. For instance, if a professor receives 7 “hots” and 6 “nots” the “hots” will be counted as “+” and the “nots” as “-”. The sum of these (7-6) equals 1, meaning the professor will receive a chili pepper. If the result had been negative, the professor would not receive a chili pepper. Professors are ranked by highest numerical value in this case. For instance a -3 result is higher than a -4.
Highest Rated Schools
School rankings are based partially on the above professor ratings. In order to assemble a school’s rating, we include both its overall Professor Average rating, as well as its Overall School Rating which is an average of its campus ratings**. We weigh professor ratings and campus ratings equally (50% each) which implies that a top school scores high both in terms of academics as well as campus life. Similar to the professor ratings, in order to provide statistically reliable trends, we only admit schools with at least 30 rated professors and 30 campus ratings. Using the resulting scores, schools are ranked from high to low.

** Campus Ratings is an element on RMP that allows students to rate schools based on reputation, location, career opportunities, school library, campus grounds and common areas, internet speed on campus, food on campus, clubs and events, social activities and whether or not the student is happy with their decision to attend the school.
