District of Columbia Interscholastic Athletic Association
Is the public high school athletic league in Washington, D.C. The league was founded in 1958. The original high school conference for D.C. schools was the Inter-High School Athletic Association, formed around 1896. That organization was segregated, and black schools in the District formed their own athletic association. Integration came with the formation of the DCIAA. For more information click here.
