Tri-County Athletic Association

The Tri-County Athletic Association is a high school athletic league that is part of the CIF Southern Section. It is an amalgamation of the Frontier League and the Tri-Valley League. Members are located in Santa Barbara County and Ventura County, with Malibu High School in a far western finger of Los Angeles County. The amalgamation effect allows schools within this group to play against other schools of equal strength in each sport.
