This article offers a case study of a graduate class in communication research methods with a service-learning approach. Students were engaged in evaluating the public information campaign of a nonprofit organization exposing human rights abuses in US prisons. They gained hands-on experience in the use of a variety of basic research methods and offered their client insight into its current and potential audiences. With a community partner to serve, the students understood the importance of systematic research inquiry and its value to nonprofit organizations. The project demonstrates the value of service-learning in communication education and describes how best practices can be applied for the development of similar courses in the discipline.
