The American Chiropractic Association (ACA) was founded in 1922, and in 1930 merged with the Universal Chiropractors Association to form the National Chiropractic Association (NCA). In 1963, the NCA was reorganized, once again under the title of the American Chiropractic Association.The House of Delegates (HOD), the deliberative body of the Association, is composed of 124 delegates representing all 50 states, the ACA Board of Governors, the ACAs specialty councils, the Faculty American Chiropractic Association (FACA), the Student American Chiropractic Association (SACA) and ACA's state affilates. The HOD meets once per year in person during the associations annual meeting, usually held in the first quarter of the year.
