Pi Gamma Mu's constitution defines the social sciences to include the disciplines of history, political science, sociology, anthropology, economics, international relations, criminal justice, social work, social psychology, social philosophy, history of education, and cultural geography. Faculty and administrators may also accept the privileges and responsibilities of membership in a collegiate chapter.
Membership comes only through established chapters.
Faculty chapter sponsors send membership application forms along with an institutional check to headquarters where memberships are processed. Chapters may also assess local dues. Membership in Pi Gamma Mu may increase the Civil Service rating at which a person enters federal service. In addition, other employers look for honor society status on resumes. Membership in Pi Gamma Mu is a valuable asset.
