This paper presents a study of 428 youths who participated in service-learning projects in developing countries in South-East Asia, China and India. Using mixed-method approach, this study examined the reasons for their participation in the YEP (youth expedition projects) and the impact of their service-learning experiences on their civic attitudes and competence skills. Positive outcomes in civic engagement, competence skills and development of sense of self for participants as a whole and in terms of age group are discussed. The author concludes that it is important to make service-learning an explicit training and educational goal in order for educators to facilitate the building of capacities in youths, so that they can appreciate the value that service-learning can bring in character development and shape early commitment to civic involvement.
