The Blossom Valley Athletic League is composed of 24 high schools encompassing four public school districts. The league is divided into three divisions called Mt. Hamilton, Santa Teresa, and West Valley. Schools are placed into these divisions based on the strength of each specific sports program. The value of this system is that it provides quality competition. At the end of each season, sport divisions are reassessed and a team can be reassigned based on success of the lower level programs, coaching changes, and graduating athletes. The success of this league and the philosophy of power leagues have made the BVAL a model program which is being studied throughout the United States.
