Professors’ Beauty, Ability, and Teaching Evaluations in Italy

Using data from an Italian University, we relate student evaluations of teaching quality to the physical attractiveness of instructors (as evaluated by external raters using photos), controlling for a number of teacher and course characteristics. We first show that teachers’ beauty significantly affects evaluations of their teaching. We carry out a number of checks to tackle threats to internal validity: course fixed effects and individual research productivity are controlled for; an IV estimation strategy is undertaken using a second measure of beauty as an instrument; and measures of grooming and fastidiousness are introduced. Notwithstanding these controls, we find that more attractive teachers receive much better evaluations.
