This study draws on interviews with community supervisors partnered with high school students and presents their perspectives on service-learning and youth. The results show that there was a hidden curriculum being played out at community sites that was in part facilitated by community agency supervisors who actively engaged in mediating, mentoring, and structuring the service-learning experiences of students. Agency supervisors' decisions about the curricular experiences of students had a significant impact on the social justice aims and intentions of the projects designed by the teachers. Consequently, it is crucial for schools and teachers to take into consideration the community supervisors' perspectives and interpretations of social justice and invite them into a collaborative partnership throughout the process of structuring service-learning experiences.
