This article describes the development of an undergraduate interdisciplinary global citizenship program. The process of program development was guided by the core belief that students need not only information and skills, but the tools to develop their own individual citizenship in today's world. Using document analysis, interviews with key informants and survey data from faculty involved in course development and delivery, the authors examine the challenges of construct definition, of establishing learning outcomes, and of program assessment that confronted the program developers. The article concludes with an exploration of the underlying assumption that university programs are effective means for building an engaged citizenry. (Contains 1 table.)
