This course introduces students to a widely acclaimed, holistic perspective on both individuals and teams. It is an overview course focused the three perspectives in which CDF-users view clients: the social-emotional, cognitive, and psychological one. Insight into these dimensions stems from decades of validated research since the 1970s but has not been widely taught in a unified fashion. In the course, emphasis is placed as well on the interrelationships between the three dimensions since they closely interact in coaching as well as consulting. Based on this course, students become eligible for all other CDF courses.
