Welcome San Mateo Region 36 Referees

Volunteer referees are needed to officiate at every AYSO game, so we need your help! You'll be trained and provided the necessary equipment (e.g., uniform, flags, whistle, etc.). Without trained referees, the kids can't play!

Becoming a Volunteer Referee

Each U6 and U8 game needs two trained and certified volunteer referees (one from each team) on the field. The two referees monitor the game to make sure the kids are safe and have fun. To be trained and certified, the volunteer referee must complete:

  1. An e-signed Volunteer Registration Form every year through
  2. "Safe Haven" training at least once every two years through
  3. U6-U8 Referee training. See our 2016 U6-U8 Referee Flyer.

Each U10, U12, and U14 game requires a trained and certified three person referee team on the field, consisting of a referee and two assistant referees. Each team must provide two volunteers who will serve as assistant referees or the referee (Regional Referee or higher). To be trained and certified, the volunteer referee must complete:

  1. An e-signed Volunteer Registration Form every year through
  2. "Safe Haven" training at least once every two years through
  3. Concussion Awareness training (one-time) through (strongly encouraged).
  4. Referee certification for the age level.
    1. For U10/U12 assistant referees and U10 referees, Assistant Referee or Basic (Regional) Referee certification, respectively, is required.
    2. For U12 referees and U14 assistant referees, Regional Referee with appropriate experience or Intermediate Referee certification is required.
    3. Assistant and Regional Referee training is now scheduled. See our 2016 Referee Flyer.
