Although sociologists have found direct links between parents' education and the high school and college educational attainments of their offspring, researchers have been surprised to find no parental effects on educational enrollments beyond college. Postgraduate matriculation appears to result from academic success in college, divorced from parents' educational capital. Using new data from the Baccalaureate and Beyond Longitudinal Study, the authors reexamine this issue and extend the literature by disaggregating graduate programs by type. They find that parents' education has no effect on their children's entry into MBA programs and only a small influence on entry into master's programs; however, there is a strong effect of parents' education on entry into first-professional and doctoral programs. The role of parental education is largely indirect, working primarily through the characteristics of a student's undergraduate institution, academic performance, educational expectations, and career values. In addition, college performance maintains a strong, independent effect on enrollment in graduate school.
