This paper examines the impact of attending different categories of selective institutions on students' college completion. Specifically, it explores differences in the impact that selectivity of an institution has by race and ethnicity. The analysis accounts for the impact of individual and institutional characteristics and corrects for omitted variables with proxies for student motivation. The results suggest that students who attend the most selective institutions and highly selective institutions, as opposed to non-selective ones, are more likely to complete a bachelor's degree. This result holds for African American and Hispanic students. After correcting for the problem of sorting of students into specific types of institutions, the results of the models suggest that the coefficient of selective institutions might have a small upward bias. The positive effect of selective institutions on attainment suggests that they have the potential to increase the graduation rates of minorities while narrowing the persistent college completion gap.
