IIT hosts seven national fraternities (Alpha Sigma Phi, Phi Kappa Sigma, Pi Kappa Phi, Sigma Phi Epsilon, Delta Tau Delta, Omega Delta, and Triangle), one national sorority (Alpha Sigma Alpha), and two local sororities (Kappa Phi Delta and Zeta Phi Omega) on its Main Campus. These Greek organizations have a long history at the university; the oldest is the Alpha Epsilon chapter of Phi Kappa Sigma, which was founded in 1898, and Kappa Phi Delta, founded in 1904, is the oldest sorority in the city of Chicago. Since IIT's early years, fraternities and sororities have played an active role in campus life. Members have held roles in the Student Government Association, faculty research groups, and IIT sports. They participate in numerous student organizations, the Union Board, and work as Student Ambassadors for the Office of Undergraduate Admission and as orientation counselors. Greeks also organize intramural games and participate in the annual Greek Week, where chapters square off in everything from tug-of-war to a dance-off.
Philanthropy is a priority for members of the Greek community. Members participate in chapter philanthropy projects in addition to Greek wide philanthropy projects. Through Greek organizations members have several leadership opportunities to develop their leadership skills for life after college. Additionally, the Greek community has had a higher average GPA than the general campus population for several years.
All the Greeks, except Zeta Phi Omega and Omega Delta, operate their own chapter houses. This allows members to add even more valuable experiences to college life with responsibilities such as managing a $200,000 chapter budget, programming meals for 40 members, and coordinating with living IIT Greek alumni.
