Wellesley College does not have any fraternities or sororities; it does, however, have a number of societies centered around common academic interests. There are currently six active societies on campus: Alpha Kappa Chi (the "history" society), Alpha Phi Sigma (the "lecture" society), Tau Zeta Epsilon (the "art and music" society), Zeta Alpha (the "literature" society), Agora Society (the "political science" society), and Shakespeare Society. The societies sponsor many lectures and events on campus, and contribute funding to events sponsored by other departments and organizations. They have an application process called "tea-ing", and organize on-campus parties. The majority of students are not members of societies.
