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.
These organizations are similar to "social" fraternities and sororities, with the exception of being coed and non-residential. In , Chi Phi began allowing transgender members, or those identifying as male, to join the social fraternity.
These federal structures are largely governed by alumni members of the fraternity, though with some input from the active student members.
Most Greek letter organizations select potential members through a two-part process of vetting and probation, called rushing and pledging, respectively, though the terms recruitment and new member period are preferred today.
Usually, after a potential new member has attended several such events, officers or current members meet privately to vote on whether or not to extend an invitation known as a "bid" to the prospective applicant.
Those applicants who receive a bid, and choose to accept it, are considered to have "pledged" the fraternity or sorority, thus beginning the pledge period new member period.
Students participating in rush are known as "rushees" Potential New Members "PNMs" while students who have accepted a bid to a specific fraternity or sorority are known as "new members" or in some cases "pledges.
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.
At the conclusion of 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.
Many Greek-letter organizations give preferential consideration for pledging to candidates whose parent or sibling was a member of the same fraternity or sorority.
Such prospective candidates are known as "legacies. Membership in more than one fraternity or sorority is almost always prohibited.
Recently, some Greek-letter organizations have replaced the term "pledge" with that of "associate member" or "new member". Sigma Alpha Epsilon , in , abolished pledging altogether.
Potential members are now immediately initiated into the fraternity upon accepting a bid. A single undergraduate fraternity chapter may be composed of anywhere between 20 and more than students, though most have an average of about 35 to 45 members and pledges.
Some fraternities and sororities are un-housed, with members providing for their own accommodations. In many of these cases, the fraternity or sorority own or rent a non-residential clubhouse to use for meetings and other activities.
With a few exceptions, most fraternities and sororities are secret societies. While the identity of members or officers is rarely concealed, fraternities and sororities initiate members following the pledge period through sometimes elaborate private rituals, frequently drawn or adopted from Masonic ritual practice or that of the Greek mysteries.
Some fraternities also teach initiates an identity search device used to confirm fellow fraternity members. 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.
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 was hampered in part because fraternity members refused to disclose the location of the hidden chapter room, where the conflagration had erupted, to emergency responders.
The fraternity or sorority badge is an enduring symbol of membership in a Greek letter organization. Most fraternities also have assumed heraldic achievements.
Members of fraternities and sororities address members of the same organization as "brother" in the case of fraternities or "sister" in the case of sororities.
There are a few exceptions to this general rule, as in the case of the fraternities Triangle , Acacia , and Seal and Serpent.
There are approximately 9 million student and alumni members of fraternities and sororities in North America, or about 3 percent of the total population.
Roughly , of the current fraternity and sorority members are students who belong to an undergraduate chapter. Winnings are processed quickly for your convenience.

A Gallup survey of 30, university alumni found that persons who said they had been members of Greek-letter organizations while undergraduates reported having a greater sense of purpose, as well as better social and physical well-being, than those who had not.
Greek letter organizations have often been characterized as elitist or exclusionary associations, organized for the benefit of a largely white, upper-class membership base.
Members of fraternities and sororities disproportionately come from certain socio-economic demographics, which perpetuates an unhealthy divisiveness within the student body based on ethnicity and income and a perpetuation of patterns of exclusivity and privilege.
