Stratification in college entry and completion

This paper examines stratification of opportunities in college access and completion. Using propensity score methods, we investigate two comparisons: (1) four- versus two-year public colleges and (2) private versus public two-year colleges. While previous research finds lower degree completion in two-year than in four-year public colleges, the comparability of students is doubtful. This paper re-considers the public four-year college effect, but for similar students and additional relevant outcomes. The second comparison is a new one. Though recruiting similar students as public two-year colleges, private two-year colleges use different organizational procedures, and we find that they have a different impact on comparable students’ degree completion. We speculate about the reasons for these differences and whether they suggest potential benefits of adapting these procedures for public two-year colleges.
