Become an AYSO Referee



Become an AYSO Referee

AYSO depends on volunteer referees. We are a 100% volunteer organization.
If we don’t have referees, games don’t happen.

Refereeing is a fun, active way to stay involved with your player, learn the game, and support a safe, fair, and positive experience for all players. Compared to coaching, it is a flexible and lower time commitment; you choose the games that fit your schedule.

No prior experience is required. AYSO provides training, mentorship, and support.

Why Referee?

  • Support your player’s team and the AYSO community
  • Help ensure games are safe, fair, and fun
  • Flexible commitment—no weekly obligation
  • Great way to learn and understand the game
  • Build leadership, confidence, and communication skills

How Refereeing Works

  • Referees sign up for games based on their availability
  • You choose the level you are comfortable officiating
  • New referees are supported and paired with experienced referees when possible
  • Many new referees start as 10U Assistant Referees or with 8U games

06U games do not use referees
Coaches help guide play at this level

07U/08U games require 08U Referee Certification
(Online training only)

09U/10U games require the Regional Referee Certification 
(Online training plus in-person field session)

12U+ games require higher level Certification that builds off of the Regional Referee Certification.  For details please contact our Ref Admin!
