With the overarching goal of cultivating global citizens, many higher education institutions have developed and implemented co-curricular leadership programs for their constituents. Quantitative research on the impact of leadership programs on undergraduate students has shown an increase in self-awareness and social consciousness, both characteristics of global citizens. Yet, research has failed to adequately address the impact of leadership programs on global students' sense of self. Global students include any individual who has spent a significant portion of their developmental years outside the country of higher education, including international students, children of international religious missionaries, international military personnel, international businesspeople or government diplomats. The central question that informed this qualitative inquiry was: How do former global students who participated in a co-curricular intercultural leadership program describe the impact of their involvement on their current sense of self in post-baccalaureate life? For this qualitative inquiry, grounded theory case study was utilized to explore the experiences of 15 former global students who participated in a co-curricular, intercultural leadership development program. This empirical research into the impact of co-curricular leadership programs on global students' sense of self in their post-baccalaureate life contributed to the theory of intercultural competence development. It also provided practical implications for the components of high impact leadership programs as well as the value of providing developmental programs for global students.
