Welcome to the Graduate School of Arts and Sciences at Yale University, the first graduate school in North America. The Graduate School stands at the very heart of Yale’s mission as a university and has worked to extend and enrich the sense of community found individually within Yale's departments and programs. Maintained on this website is a continually evolving portrait of the extraordinary breadth of Yale's graduate programs and the exceptional services, activities and events that enhance graduate study and graduate student life at Yale.
