Despite a growing emphasis on international offerings within social work education, researchers have conducted few outcomes studies regarding the implications of these courses for students' professional development. This study addressed this gap by analyzing data from a survey of 122 social work students at Rutgers, the State University of New Jersey, before and after they completed (a) a guided study-abroad course or (b) an on-campus course on international social work. Results indicated that students in both courses demonstrated gains across multiple domains, including self-rated skills, understanding of international service, identification as a global citizen, and empowerment. Students in the study abroad courses demonstrated greater gains in self-rated skills than students in the on-campus course. (Contains 3 tables.)
