To examine the problem of underrepresentation of minority students in doctoral programs, the author utilized a mixed-methods case study of an online doctoral program in which large numbers of African American and Latina/o students were enrolled. Themes uncovered in the study centered on specific academic and nonacademic challenges, the important role of mentors, and the impact of degree completion on students. Recommendations include effective mentor-mentee matching and increased sensitivity to particular challenges for underrepresented minority students in doctoral programs.
