How to become a refereePrintable

Congratulations! So, you want to become a referee. That is great. As a referee you:

    • Are well paid.
    • Are part of the third team on the field with friends and colleagues.
    • Have an up close and personal interaction with the players and the game.

Already a referee? Register with the Peninsula Soccer Referee Association

To get started as a referee you need:

  • A license
  • A kit (jersey, shorts, socks, flags, whistle, watch, notebook, etc.)
  • Mentored matches


Most matches assigned via the Peninsula Soccer Referee Association require a United States Soccer Federation Referee License. As a USSF Referee, you will be part of the California North Referee Association. More information about becoming a referee is available on the CNRA Website.-> You get a Grassroots Referee License.

To get a license you need to take a class, called an "Grassroots Entry Level Course". If you are 18 years old or older, the class involves:

  1. A background check
  2. On-line Health and Safety Course
  3. On-line SafeSport Course (mandated by law)
  4. On-line Grassroots Referee Course
  5. On-line quiz
  6. A field session

If you are 13-17 years old, the class involves:

  1. On-line Health and Safety Course
  2. On-line Grassroots Referee Course
  3. On-line quiz
  4. A field session

The background check can take 7 to 10 days. 
You MUST complete all the background check BEFORE attending the field session. 
You MUST complete all the on-line material BEFORE attending the field session.

You need on-the-field experience and advice. Some leagues (San Francisco Youth Soccer for example) will assign a Mentor to help during your first matches. Some Clubs have a Director of Referee Development or similar title to help you.

More experienced referees love to help rookies. At your matches, ask for pointers. Tell your referee team about your experience level.

Work recreational level matches (AYSO in San Mateo County) before you work competitive level matches.
