Student evaluations of teaching are ubiquitous in the academe as a metric for assessing teaching and frequently used in critical personnel decisions. Yet, there is ample evidence documenting both measurement and equity bias in these assessments. Student Evaluations of Teaching (SETs) have low or no correlation with learning. Furthermore, scholars using different data and different methodologies routinely find that women faculty, faculty of color, and other marginalized groups are subject to a disadvantage in SETs. Extant research on bias on teaching evaluations tend to review only the aspect of the literature most pertinent to that study. In this paper, we review a novel dataset of over 100 articles on bias in student evaluations of teaching and provide a nuanced review of this broad but established literature. We find that women and other marginalized groups do face significant biases in standard evaluations of teaching -- however, the effect of gender is conditional upon other factors. We conclude with recommendations for the judicious use of SETs and avenues for future research.
