AYSO Crossover

US Soccer offers a one-time Crossover option for AYSO referees who are currently Intermediate or Advance level.

This option allows an existing AYSO referee in either of those levels to become a U.S. Soccer referee and bypass a few entry level requirements.

Crossover referees do NOT need to take a three-hour field training or complete the four-hour online referee course.

They simply pay the registration fees and complete the LiveScan process for Cal South.

Please note that state and federal compliance trainings are still needed. If you have already completed those trainings, we simply need copies of your certificates for SafeSport, Concussion, and Sudden Cardiac Arrest.

Please download and print the AYSO Crossover Checklist using the button below to monitor your progress.
