Student evaluations of teaching are not only unreliable, they are significantly biased against female instructors

A series of studies across countries and disciplines in higher education confirm that student evaluations of teaching (SET) are significantly correlated with instructor gender, with students regularly rating female instructors lower than male peers. Anne Boring, Kellie Ottoboni and Philip B. Stark argue the findings warrant serious attention in light of increasing pressure on universities to measure teaching effectiveness. Given the unreliability of the metric and the harmful impact these evaluations can have, universities should think carefully on the role of such evaluations in decision-making.
