Service-learning courses offer a unique experience to students by reinforcing typical school curriculum with experiences outside the classroom, where the emphasis is on learning by doing accompanied with reflection (Conrad & Hedin, 1981). Studies show that the quality of the service-learning experience has the potential to impact student outcomes; however, few have looked at the relationship of quality with engagement and self-efficacy (Holland et al., 2009). Thus, this study focused on the effects of quality of service-learning experience on student engagement through leadership self-efficacy and community service self-efficacy. A survey of 105 students showed a significant mediation model of quality of service-learning on affective student engagement through leadership self-efficacy and community service self-efficacy. Significant direct effects were found between quality of service-learning and leadership self-efficacy, community service self-efficacy, and student engagement. These findings on quality of service-learning courses have implications for students, educators, and universities.
