This paper investigates the impact of class attendance on student performance in an Intermediate Microeconomics class at the University of the West Indies (UWI), Mona. The UWI is the foremost and most prestigious university in the Anglophone Caribbean. It serves 18 countries and territories across the West Indies. No other study has explored this relationship in this area of the world. The author controls for a large number of student characteristics as well as the university characteristic class size. Because of well-known endogeneity issues, both ordinary least squares (OLS) and two-stage least squares (2SLS) are used to estimate the model. The results indicate that class attendance does have a positive impact on the student’s grade, and that it may be possible to find suitable proxies for motivation and ability.
