Many faculty developers recognize that in order to have a major impact on key faculty outcomes, such as educational leadership, scholarship, and skill development, it is often necessary to make substantial investments in faculty members. Although there are a variety of ways of making this investment, extending the duration and increasing the frequency of faculty development activities is a straightforward solution. Providing an intensive, longitudinal series of activities for a cohort of faculty also fits well with institutional goals to develop faculty members with more sophisticated levels of skill in particular domains. This chapter describes some of the characteristics of longitudinal programs for faculty development, which may include a certificate, fellowship, or advanced degree and are designed to provide faculty members with intensive training in a specific set of skills over an extended period of time (6 months or more).
