PURPOSE This study aimed to explore the re-socialization process of college soccer players who rejoin college soccer clubs after dropping out. METHODS A case study approach was employed, and participants were selected using the snowball sampling method. Data were collected through in-depth interviews, participant observation, and literature reviews. The authenticity of the data was validated through triangulation, member checking, and peer debriefing. All research procedures were conducted following approval from the institutional review board. RESULTS The study revealed several key findings. First, participants faced numerous challenges during the re-socialization process into sports, including interpersonal, academic, and emotional difficulties. Second, distinctive features of the re-socialization process emerged, including the determination and effort required for adapting to university life, support from socialization agents within the university, and rapid re-socialization following dropout. Third, experiences within collegiate soccer clubs indicated low barriers to entry for former athletes, academic success through complementary relationships, a hierarchical culture familiar to student-athletes, and enhanced satisfaction in interpersonal relationships and a sense of belonging. CONCLUSIONS This study underscores the importance of institutional support that enables college athletes to participate in sports clubs, facilitating the successful re-socialization of athletes who have dropped out.
