Omicron Delta Kappa, the National Leadership Honor Society, recognizes and encourages superior leadership and exemplary character. O∆K encourages collaboration among members across the five phases celebrated by O∆K:  scholarship, athletics, service, communications, and arts. Founded in 1914 at Washington and Lee University, O∆K honors and develops leaders through scholarships, workshops, career opportunities, leadership resources, and a lifelong connection to other members.

USK students who are eligible can become members of this honors society by joining the institutional Circle (chapter). Elections of officers and new members are held on campus every year.
