With the fundamental shifts in the delivery of health care and overwhelming concern about the health of populations around the globe, there is widespread agreement that the reform of health professions education is essential across the continuum from prelicensure through continuing professional development (Frenk et al., 2010). These reforms have sparked an explosive growth in graduate programs in health professions education that prepare clinicians for teaching and leadership roles in higher education, clinical settings, community settings, professional associations, and regulatory agencies. This chapter provides the background of the changing context of health-care delivery and the need for reforming health professions education (HPE) across the continuum. An overview of the growth and curricula of graduate programs designed to prepare the health professions education workforce is discussed, along with the rationale for including foundational adult and continuing education theory and research in the curricula of graduate programs. The chapter concludes with a discussion of future trends in HPE graduate programs.
