Region 35: Serving Cupertino and Neighboring Cities

Want to be a Referee? Thank you.

Referees are critical to soccer just as players and coaches. In AYSO, the game can’t be played if there aren’t enough referees. All our referees are volunteers, just like everyone else in AYSO.  We will train everyone who signs up to volunteer as a referee, and that means anyone 12 years old and up (yes, Grandparents can help, too!)

Volunteer as a Referee

There are multiple requirements to become an AYSO Referee

  1. Complete the volunteer application on this Sports Connect based website each school year if you are volunteering for Region 35 (Fall through Spring)
  2. Complete the Safe Haven certification. This can be done on the new training platform EtrainU. EtrainU can be accessed from your account’s volunteer tab using AYSOU button (visible post volunteer registration).
  3. Complete Regional Referee certification course
    1. One option is to do the online course for Regional referee on etrainu. Click on Training Library and Enroll for "Regional Referee - Online + In-Person Companion Course (2 Part Bundle)". Follow the online course with an on-field session conducting by AYSO
    2. Alternatively, attend a full Regional referee course (less frequently scheduled)
  4. Complete the Concussion Awareness training on EtrainU (AYSOU).
  5. As required by California State Law, Complete the Sudden Cardiac Training which has been recently mandated by the state of California (same location in etrainu with the AYSOU button in the Volunteer tab)
  6. As required by Law for Youth sports, starting in 2022, Complete the SafeSport course through If you have completed this course already along with current annual updates for any other institution like US Soccer, the information can be synchronized and you don't have to repeat it.
  7. California also requires volunteers of youth organizations to fingerprint once for specific criteria. Look for the next scheduled event for this.

Note that Referee courses are offered periodically in our Region and Area.  Courses are listed on EtrainU and potentially in the Area website at

A lot of useful information for referees is also available in the area website at Please email [email protected] for any questions about refereeing in AYSO.

Referee Training

The next in-person referee companion training is on 4/11 and 4/12. On 4/11, there will be class room session to review and 4/12 will feature field session. Both sessions are required for completing certification. The class registrations is available on AYSOU/etrainU (the new training platform for AYSO). The Cupertino library Think tank room is used on 4/11 and a minimum of 3 attendees is required for this course to meet the library room requirements.
