Student exchange programs host many benefits for students' self-development, one of which is self-confidence. Having self-confidence is critical for students with sports backgrounds in pursuing careers as physical education teachers, athletes, coaches, sports therapists, and other sports-related jobs. However, few research aware of the importance of environment and life experience, such as joining an exchange program, in boosting students' self-confidence. This study examined the contribution of student exchange experience's to sports students' self-confidence. A structured interview was conducted with students from the Department of sports science, Faculty of Sports Science, UNNES, who run an overseas community service project at the department of physical and health education, the Faculty of Education, UiTM. The study adopts Lauster's theory of selfconfidence, one of which is believing in yourself. It revealed that students who conducted this international exchange showed a high trust to their own abilities and reflected in their actions during the program and after completing the program. Seeing that self-confidence could direct students to accomplish their International project goals, this research would suggest students enhance their self-confidence by immersing themselves in a supportive environment and challenging themselves in productive activities to get more life-skill experiences. Further research should elaborate on all factors which shape students' selfconfidence.
