# Professional Fraternity Association

The Professional Fraternity Association (PFA) is an American association of national, collegiate, professional fraternities and sororities that was formed in 1978. Since PFA groups are discipline-specific, members join while pursuing graduate (law, medicine, etc.) degrees as well as undergraduate (business, engineering, etc.) degrees. PFA groups seek to develop their members professionally in addition to the social development commonly associated with Panhellenic fraternities. Membership requirements of the PFA are broad enough to include groups that do not recruit new members from a single professional discipline. The PFA has welcomed service and honor fraternities as members; however, Greek letter honor societies more commonly belong to the Association of College Honor Societies.

## History

The Professional Panhellenic Association (PPA), for women's groups, was founded in 1925, and the Professional Interfraternity Conference (PIC), for men's groups, was founded in 1928. These groups came about due to rapid growth among all types of fraternities during the late 1920s.

### Professional Panhellenic Association

On June 26, 1925, representatives from fourteen professional fraternities for women attended an organizational meeting in Washington, D.C. During the summer a provisional constitution was ratified by the following eleven fraternities: Delta Omicron (music), Kappa Beta Pi (law), Omicron Nu (home economics), Phi Beta (music and speech), Phi Delta Pi (physical education), Phi Chi Theta (commerce), Phi Delta Delta (law), Phi Upsilon Omicron (home economics), Pi Lambda Theta (education), Sigma Sigma Sigma (education), and Theta Sigma Phi (journalism). Two additional fraternities, Sigma Alpha Iota (music) and Iota Sigma Pi (chemistry), soon ratified the constitution. The resulting thirteen member groups participated in the second annual conference on November 26, 1926.$^{:14}$ Originally known as Women's Professional Panhellenic Association until 1941, when the revised name was adopted.$^{:14}$

### Professional Interfraternity Conference

On March 2–3, 1928, delegates from 27 professional fraternities came together in Washington, DC to organize the PIC. Jarvis Butler of Sigma Nu Phi was elected as the first president, and Stroud Jordan of Alpha Chi Sigma was elected as the first Secretary-treasurer.
Groups represented were$^{:13}$

## Professional Fraternity Association

The PFA resulted from the merger of the Professional Interfraternity Conference and the Professional Panhellenic Association in 1978. The merger itself was the result of the impact of Title IX on most fraternal groups with professional affiliations.
