San Pasqual Valley High School is part of the Arizona Interscholastic Association.

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.

[2] In 2005, CIF began requiring that all student athletes sign a pledge not to take any steroids or face suspension or expulsion.

[7] The Southern Section is the largest by both membership and geography, covering just under one-third of the state's total area and almost half of the population base.

The Southern section includes private schools in the LAUSD service area, whether inside or outside the city of Los Angeles, and the Central Coast and North Coast sections also include private schools in the cities of San Francisco and Oakland respectively.

The sections also serve as the qualifying entities for regional and state competitions, and may organize championships in sports not contested statewide, such as badminton, baseball, field hockey, gymnastics, lacrosse, skiing and snowboarding, soccer, softball, and water polo.
