Using the Baccalaureate and Beyond Survey of 1992/93 longitudinal cohort survey, we investigated (a) whether and how much variations in the timing of enrollment, the type of undergraduate institution attended, and type of graduate program pursued contribute to observed racial and ethnic differentials in postbaccalaureate enrollment; and (b) whether the observed enrollment differentials carry over to degree attainment. Dynamic event history methods that account for both the timing of matriculation and the hazard of enrolling revealed that compared with Whites, underrepresented minorities enrolled earlier and were more likely to enroll in doctoral and advanced professional degree programs relative to nonenrollment. Our results revealed sizable differences in the cumulative probability of advanced-degree attainment according to the undergraduate institutional mission, with graduates from research institutions enjoying a decided advantage over liberal arts college graduates. The conclusion discusses limitations of the analysis, directions for further research, and implications for strengthening the minority pipeline to graduate school.
