The University of North Carolina at Chapel Hill College of Arts and Sciences The Cluster Program encourages you to make connections among courses offered across several disciplines in the College of Arts and Sciences. A cluster is a group of courses organized around a common theme and representative of different disciplinary approaches to defining and engaging in an intellectual problem. You may take any three courses in a cluster, but we recommend beginning with a core course. Many cluster courses satisfy Approaches and Connections requirements, but their principal advantage is the opportunity they offer you to examine a topic from the perspective of several disciplines.
