Alpha Psi Omega was organized at Fairmont State College in Fairmont, W.Va., in 1925. It was decided that each chapter should be called a cast, and Fairmont became Alpha cast. The interest of Marshall College in Huntington, W.Va. assured the immediate national chapter of Alpha Psi Omega with the establishment of Beta cast. A member of Beta cast suggested the name Playbill for the national publication.
Alpha Psi Omega has enjoyed continuous national growth, and with over 550 chapters is the largest national honor society in America. Membership in Alpha Psi Omega is granted only to fully accredited institutions with a four-year curriculum in theatre and drama leading to a degree.
The Theta Phi cast of Alpha Psi Omega was founded at Susquehanna in 1942.
