Gender exclusivity Fraternities and sororities traditionally have been single-sex organizations, with fraternities consisting exclusively of men and sororities consisting exclusively of women. In the United States, fraternities and sororities have a statutory exemption from
Title IX legislation prohibiting this type of gender exclusion within student groups, and organizations such as the
Fraternity and Sorority Political Action Committee lobby to maintain it. Since the mid-20th century, a small number of fraternities, such as
Alpha Theta and
Lambda Lambda Lambda, have opted to become co-educational and admit female members; however, these generally represent a minority of Greek-letter organizations and no such fraternity is currently a member of the North American Interfraternity Conference, the largest international association of fraternities. Much more commonly, coed fraternities exist in the form of service fraternities, such as
Alpha Phi Omega and
Epsilon Sigma Alpha and others. These organizations are similar to social fraternities and sororities, except they are coed and non-residential. Similarly, in the United States, professional fraternities, such as
Alpha Kappa Psi,
Delta Sigma Pi, and
Phi Gamma Nu, are required to be co-ed under the
Title IX amendments, as are any fraternities that are not social. In 2014,
Sigma Phi Epsilon became the first fraternity in the
North American Interfraternity Conference to accept transgender members, or those identifying as male, to join the social fraternity. Several sororities have adjusted their policies to confirm that transgender prospective members are allowed. Importantly, all these variants have stemmed from a process of self-determination, without challenge by other fraternities and sororities. In a
bellwether case in 2016,
Harvard University changed its student conduct code to bar members of single-sex groups from leading campus groups, serving as captains of sports teams, or participating in valuable academic fellowships. This is being contested vigorously in U.S. federal court by several affected fraternities and sororities.
Governance Individual chapters of fraternities and sororities are largely self-governed by their active (student) members; however, alumni members may retain legal ownership of the fraternity or sorority's property through an alumni chapter or alumni corporation. All of a single fraternity or sorority's chapters are generally grouped in a national or international organization that sets standards, regulates insignia and ritual, publishes a journal or magazine for all of the chapters of the organization, and has the power to grant and revoke charters to chapters. These federal structures are largely governed by alumni members of the fraternity, though with some input from the active (student) members.
Leadership The leadership structure of a typical college fraternity chapter is designed as a hierarchical "Executive Board" that mirrors corporate or civic governance to ensure the chapter's operational stability. At the top is the President, who serves as the primary liaison between the chapter, the university administration, and the national headquarters. Supporting the President are several key officers: the Vice President, who often oversees internal committee operations; the Treasurer, responsible for managing the chapter's budget and dues collection; and the Secretary, who handles records and communications. Specialized roles such as the Recruitment Chair (responsible for growth), the Risk Manager (ensuring safety and policy compliance), the
Serjeant-at-arms (counting votes and ensuring attendance), and the Scholarship Chair (monitoring academic performance) are also standard. A new member period may last anywhere from one weekend to several months. During this time, new members might participate in almost all aspects of the life of the fraternity or sorority, but most likely not be permitted to hold office in the organization. After the new member period, a second vote of members may sometimes be taken, often, but not always, using a
blackball system. New members who pass this second vote are invited to a formal and secret ritual of initiation into the organization, advancing them to full membership. Membership in more than one fraternity or sorority is acceptable, but only under specific Greek councils. Recently, some Greek-letter organizations have replaced the term "pledge" with that of "associate member" or "new member".
Sigma Alpha Epsilon, in 2014, abolished pledging altogether. Potential members are now immediately initiated into the fraternity upon accepting a bid.
Residency chapter house at the
University of Illinois Urbana-Champaign Unique among most campus organizations, members of social fraternities and sororities usually congregate and sometimes live together in large houses, generally privately owned by the organization or by the organization's alumni association. Often, fraternities and sorority houses, called lodges or chapter houses, are located on the same street or in close quarters within the same neighborhood, which may be colloquially known as "Greek row", "frat row", or "sorority row". Often, chapter houses are uniquely designed, highly elaborate, and very expensive to operate and maintain. Chapter houses became more common in the late 19th century, when organizations began to grow in size, and wealthy alumni were able to help purchase or build houses.
Alpha Tau Omega became the first fraternity to own a residential house in the
South when, in 1880, its chapter at the
University of the South acquired one. Chapters of many fraternities followed suit, purchasing and, less often, building them with the support of alumni.
Phi Sigma Kappa's chapter home at Cornell, completed in 1902, is the oldest such house still occupied by its fraternal builders. Usually, the more expensive the house, the higher the annual organization dues. The features and size of chapter houses play a major role in chapters remaining competitive in recruiting and retaining members on many campuses.
Julian Hawthorne, the son of
Nathaniel Hawthorne, wrote in his posthumously published
Memoirs of his initiation into
Delta Kappa Epsilon: I was initiated into a college secret society—a couple of hours of grotesque and good-humored
rodomontade and horseplay, in which I cooperated as in a kind of pleasant nightmare, confident, even when branded with a red-hot iron or doused head-over-heels in boiling oil, that it would come out all right. The neophyte is effectively blindfolded during the proceedings, and at last, still sightless, I was led down flights of steps into a silent crypt and helped into a coffin, where I was to stay until the Resurrection...Thus it was that just as my father passed from this earth, I was lying in a coffin during my initiation into Delta Kappa Epsilon. Meetings and rituals are sometimes conducted in what is known as a chapter room located inside the fraternity's house. Entry into chapter rooms is often prohibited to all but the initiated. In one extreme case, the response of firefighters to a blaze signaled by an automated alarm at the
Sigma Phi chapter house at the
University of Wisconsin in 2003 was hampered in part because fraternity members refused to disclose to emergency responders the location of the hidden chapter room, where the conflagration had erupted.
Symbols and naming conventions (left),
Delta Sigma Pi (center), and
Phi Kappa Phi (right) Dating back to their origins in the 19th century, fraternities and sororities adopted symbolism from the ancient Greeks and Romans, chivalric traditions, and Jewish and Christian scripture learned in their classes, along with some influences of Freemasonry. The fraternity or sorority badge is an enduring symbol of membership in a Greek letter organization, and often incorporates the organization's Greek letters and various symbols. == Membership profile ==
