What's looks got to do with it? Instructor appearance and student evaluations of teaching

Some studies suggest that instructors' looks are important determinants of their Student Evaluations of Teaching (SET) results. Yet the studies examining this proposition leave out many independent variables that have been found to be important determinants of SETs in the SET literature. This study adds in most such factors and finds that, controlling for these other factors, attractiveness has no effect in our data. We conclude that earlier findings indicating that instructor appearance is important are likely due to omitted variable bias. © 2005 by the Association for Public Policy Analysis and Management
