Omicron Delta Kappa or ODK, a national honor society, was founded at Washington and Lee on December 3, 1914. ODK's annual Convocation is held at the school in Lee Chapel on or about Robert E. Lee's birthday, January 19, in conjunction with a Board-mandated university holiday/Lee commemoration called "Founders Day," a version of the Robert E. Lee birthday holiday still officially celebrated in a few Southern states. ODK 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 with regard to the way in which 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. Omicron Delta Kappa continues to maintain its headquarters in Lexington and is a major presence at W&L.
