Abstract: Using student evaluations as a learning measure, we estimate and compare class size and teacher effects for higher education, with emphasis on determining whether a comprehensive class size reduction policy that draws on the hiring of new teachers is likely to improve educational outcomes. We find that teacher effects far outweigh class size effects, and that young teachers and first time teachers perform significantly worse than their peers. Furthermore, we study whether teacher effects are correlated with observables, and find no significant variables beyond being a full time teacher. Overall, these findings suggest that at the higher education level the optimal strategy is to have large classrooms with highly qualified teachers.
