As U.S. Extension broadens its reach around the globe, an increased need exists for Extension professionals who have not only technical knowledge but also the cultural competencies to apply that knowledge in international settings. We describe a course that provides students with the opportunity to develop skills needed for potential careers in Extension, especially those involving international focuses, while advancing U.S. Extension's international efforts. The course also may serve as a model for instructors wishing to integrate Extension concepts into their teaching of undergraduates, thereby preparing individuals to make immediate impacts in Extension careers.
