The California Interscholastic Federation (CIF) is the governing body for high school sports in the U.S. state of California. CIF membership includes both public and private high schools. Unlike most other state organizations, it does not have a single, statewide championships for all sports; instead, for some sports, the CIF's 10 Sections each have their own championships. Six schools near the state border are members of adjacent state's associations. San Pasqual Valley High School is part of the Arizona Interscholastic Association. Coleville High School, Needles High School, North Tahoe High School, South Tahoe High School and Truckee High School are part of the Nevada Interscholastic Activities Association. History As early as 1891, schools around the San Francisco Bay Area began competing against each other in football organized by the Amateur Academic Athletic Association. Other boys sports were added starting 1894, organized by the Academic Athletic League. While teams represented the schools by name, there was no affiliation with the school administration. The CIF was founded in Los Angeles in 1914 by a group of area school principals. It was founded in order to standardize rules and team structures between schools; it was also intended to prevent abuses such as "school shopping" by athletes and teams fielding players over high school age. Other school principals voluntarily entered into the program, and by 1917, the organization was established statewide. In 2005, CIF began requiring that all student athletes sign a pledge not to take any steroids or face suspension or expulsion. This action was the first of its kind from a statewide high school athletics association in the United States.
