All students take the full-year core course in their first year, which serves as an introduction to health policy. Overseen by the Committee on Higher Degrees in Health Policy, the core course is a survey course that meets for four hours per week. It has several modules, each supervised by a faculty member. Within a module, each class is generally given by a different Harvard faculty member, although some faculty give multiple sessions. The supervising faculty member, who attends each session within a module, provides continuity across those sessions; the numerous faculty giving sessions within each module expose the students in their first year to the many faculty they may consider working with during the dissertation stage.
