Institutional and ethnic variations in postgraduate enrollment and completion.

Using the B&B:93/03 longitudinal cohort survey, we investigate (1) 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 post-baccalaureate enrollment, and (2) whether the observed enrollment differentials carry over to degree attainment. Dynamic event history methods that account both for the timing of matriculation and the hazard of enrolling reveal that compared to whites underrepresented minorities enroll earlier and also are more likely to enroll in doctoral and advanced professional degree programs relative to nonenrollment. Our results reveal sizable differences in the cumulative probability of advanced degree attainment according to 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.
