The purpose of this study was to examine the current status of school sport club(SSC) participation and to explore relationship between school sport participation and positive youth development. In order to do this, a survey was conducted with 403 elementary, middle, and high school teachers who are currently taking charge of SSCs, and also individual interviews were conducted with 22 students. In addition, the youths' developmental asset questionnaire was administered with 412 middle school students. The survey results from 403 teachers showed that SSCs have potential to contribute to positive youth development because teachers are placing an emphasis on character development as well as physical and social development through SSC activities. In addition, participants who regularly participate in physical activities had higher internal and external developmental assets than non-participants or irregular participants. Specifically, students participated in SSC more than twice a week had higher internal and external assets than students participate once a week. In addition, participants who engage more than one hour per session had higher internal and external assets except constructive use of time and social competence. Discussion and implications for organizing SSCs to provide developmental contexts and contents for positive youth development were provided.
