This fraternity has not confined its membership strictly to undergraduates and has admitted faculty members when they were otherwise qualified. Membership has never been conferred except by initiation. The fraternity was originally intended as a fraternity of college men as well as a college fraternity and that was the reason for the establishment of the community chapters.
Two proposed chapters Maryland Psi at Johns Hopkins and Louisiana Alpha Gamma at University of Louisiana were authorized but never established.
The chapters at Washington and Jefferson College, and the Southwestern Baptist University (now Union University) were the last surviving chapters of ΑΓ and the chapter at the University of Alabama was organized by former members of the same society. The membership of ΑΓ at other places was also largely absorbed by ΑΤΩ. The chapter at Lehigh when revived in 1903 absorbed a chapter of ΨΑΚ.
A number of the chapters have been formed from local organizations. Washington and Lee when revived in 1906 from ΧΡ; Simpson when organized from ΡΑ and when revived in 1905 from ΑΙΦ; Massachusetts Institute when revived in 1906 from ΑΩ; Albion from the E.S.S. Society; Maine from the S.I.U. Society; Western Reserve from ΨΩ; Washington from ΦΣΕ; Missouri from ΑΔ; Worcester Polytechnic from the Arms and Hammer Society; Iowa State from the Black Hawks; Kentucky from ΜΙ, and Washington State from Σ; Wisconsin from ΔΑΩ; Minnesota from ΑΤΔ; Stanford from Kalmia;
