Omicron Delta Kappa

Omicron Delta Kappa, or ΟΔΚ, also known as The Circle, or more commonly ODK, is a national leadership honor society in the United States. It was founded December 3, 1914, at Washington & Lee University in Lexington, Virginia, by 15 student and faculty leaders. Chapters, known as Circles, are located on over 300 college campuses. The society recognizes achievement in the five areas of scholarship; athletics; campus/ community service, social/religious activities, and campus government; journalism, speech and the mass media; and creative and performing arts. ODK is a quasi-secret society in regards to the way its members are selected and kept secret for a period of time.

Membership in the Omicron Delta Kappa Society is regarded as one of the highest collegiate honors that can be awarded to an individual, along with Phi Kappa Phi and Phi Beta Kappa. Some Circles limit membership to less than the top one quarter of one percent of students on their respective campuses.
