Correlation with in-class student evaluations versus formal in-class student evaluations The professor's Overall Quality rating determines whether his/her name is accompanied by a smiley face (meaning "Good Quality"), a frowny face ("Poor Quality"), or an in-between, expressionless face ("Average Quality").

Īccording to the website's help page, "a professor’s Overall Quality rating should reflect how well a professor teaches the course material, and how helpful he/she is both inside and outside of the classroom". Raters may also select up to 3 tags (from a list of 20) that describe the professor. Since the website does not require users to create an account, non-students or even professors themselves can post ratings. The rater may also share if he or she would take the professor again, if the class was taken for credit, if attendance was mandatory, if the textbook was used, and what grade he or she received in the course additionally, the rater may include comments of up to 350 characters in length. To be posted, a rater must rate the course and/or professor on a 1-5 scale in the following categories: "overall quality" and "level of difficulty". Furthermore, users may create a listing for any individual not already listed. Users may post a rating and review of any professor that is already listed on the site. The site includes 8,000+ schools, 1.7 million professors, and over 19 million ratings.
