In this article, we explicate the use of principles of best practice in the design and implementation of a service-learning course. Using 11 principles adapted from the National Society for Experiential Education, we describe a service-learning course that we conducted on communication training and development. We explain how we modified and incorporated these principles to guide our service-learning project. Finally, we offer evidence gathered from project members that underscores the benefits and challenges of using these principles of best practice in the communication curriculum.
