Both U.S. graduate school enrollments and the demand for global competency in the workforce are on the rise, but what do we know about graduate-level study abroad? The Graduate Learning Overseas (GLO) research study, implemented by IIE and launched in 2017 with support from the U.S. Department of Education, Office of International and Foreign Language Education, aims to identify the scale and scope of U.S. graduate students’ educational activities and to better understand the institutional practices around student mobility data collection. This report shares results of the first national survey to U.S. higher education institutions on this topic. The results from this survey paint a clearer picture of the graduate-level study abroad landscape and demonstrate the need for institutions to build capacity to collect graduate student mobility data to support graduate students’ needs. In addition, it aims to help researchers better serve the international education field by both improving data collection practices and developing resources for institutions.
