This study explores the relationship between service learning and moral development. During a phenomenographic examination of a service-learning project in the Midwest, researchers identified ways that participants conceived of justice. These conceptions were analyzed with a Neo-Kohlbergian approach to post-conventional moral thinking and mapped using social cartography. Findings indicate that immersion programs can provide participants with nominal opportunities for moral development and that there is a need for additional supports and future research on the longitudinal effects of service learning.
