The Impact of Class Size on Outcomes in Higher Education

Numerous studies have investigated the impact of class size on student outcomes. This analysis contributes to this discussion by isolating the impact of class size on student outcomes in higher education by utilizing a natural experiment at a selective institution which enables the estimation of class size effects conditional on the total number of students taught by a faculty member. We find that class size negatively impacts student assessments of courses and instructors. Large classes appear to prompt faculty to alter their courses in ways deleterious to students.
