The challenge and opportunity for the field of evaluation is to prepare evaluators with sophisticated interpersonal competence alongside technical research skills. This article shows that service-learning, a "real-world" pedagogical model, holds promise as a way to educate students in evaluation while developing their interpersonal skills. While other community-based approaches offer experiential applications of evaluation methods, service-learning adds the important element of reflection to deepen student learning. A course that employed the "client-based" service-learning approach, individual-to-group student assignments, practice with interpersonal skills, and ongoing reflection activities is presented as a pedagogical approach to expand the range of interpersonal skills that can be developed among students. Student surveys showed that the course conveyed many benefits beyond technical knowledge of evaluation: use and awareness of important interpersonal skills, growing insight into their community and its people, growth of professional self-confidence, and kindling an interest in the field of evaluation.
