Background
Joseph Harp Correctional Center (JHCC) is an Oklahoma Department of Corrections state prison for male inmates located in Lexington, Cleveland County, Oklahoma. The medium-security facility opened in September 1978. JHCC was named for Joseph Harp. who served as warden of the Oklahoma State Reformatory from 1949 to 1969. Regarded by his colleagues as an innovative leader and professional in the field of corrections, he recognized that a high school education was one of the greatest needs that many inmates had lacked which could prevent them from gaining legal employment and often times led to a life of crime.
