This paper reports selected results from a broader study which focused on determining students' perceptions of the development of their global citizen identity within the context of an undergraduate global citizenship program, and what students believed were aspects of the program that contributed to this growth. Findings suggest that experiences with other cultures and places gained through program-organized study abroad were perceived as being the most important element in developing students' global citizen identities and practice of cosmopolitan ideals.
