Cross-certification is available to referees of AYSO and U.S. Soccer who have been certified as referees for six months or more and who are not certified with both organizations. All games officiated for AYSO or U.S. Soccer may be applied toward the certification requirements of either AYSO or U.S. Soccer. The diagonal system of control is the only recognized system of control.
If you were previously a referee with USSF, you do not qualify for the crossover. This is only for referees that have never been a referee within U.S. Soccer. The AYSO Crossover is a one-time thing. Once you crossover to U.S. Soccer, you will have to maintain the annual renewal requirements with USSF to keep your current grade.
Once your name is on our registered officials listed posted on the Cal South website under the referee tab, you can begin to referee games. For game assignments, you will need to get together with a referee association in your area and talk to an Assignor. For a listing of referee associations, click here.
