The Canyon Athletic Association (CAA), previously known as the Arizona Charter Athletic Association, is an American non-profit regulatory organization for athletic competition among secondary schools located in Arizona. The CAA serves small non-traditional education institutions including charter schools, public schools, home school organizations, and parochial schools. As of 2014, the CAA membership consisted of approximately 125 High Schools and Junior High Schools.
The CAA is not affiliated with the Arizona Interscholastic Association which also regulates high school sports in Arizona. Most schools within the CAA are smaller than schools within the AIA.
