This study explores the role of peer influence on students' decisions to participate in study abroad. Although previous research has identified many factors that relate to study abroad participation, peer influence represents an underexplored factor for consideration in this line of research. Using the tools of social network analysis, this study finds a small but significant relationship between peer study abroad and a student's participation in study abroad. Results provide food for thought about the way peers may influence students in their decisions surrounding study abroad, both directly and indirectly. This line of inquiry has important implications for education abroad professionals who seek to leverage peer influence so that students make optimal decisions about study abroad.
