This article applies theories of giving from philanthropic studies to enhance understanding of service-learning relationships between students and community partners. Focusing on the participation motivations, outcome expectations, and satisfaction levels of community partners who have recently completed work with service-learning students, the authors find that organizations and staff supervisors engaged in service-learning are motivated both by altruistic and self-serving factors. Staff supervisors and community partner organizations are motivated to give time, training, and a laboratory to enhance student learning. In return, community partners expect and generally receive valuable service from the students. The results suggest that the service-learning relationship be viewed as reciprocal in nature, as with other donor-recipient situations. (Contains 4 tables and 1 note.)
