Institutions of higher education continue to emphasize the need to create and develop global citizen graduates who will face challenging global issues in the workforce. A systematic literature review of empirical studies on global citizenship in higher education was conducted to understand the various ways this term is being studied, measured, and operationalized. The process of inclusion and exclusion criteria identified 57 studies. A content analysis revealed global citizenship is being included into higher education through scales of measurement, studying abroad, faculty and student perceptions, coursework, and university programs. The results are discussed in relation to the current literature on global citizenship along with future avenues of research.
