Keeping The Game Safe, Fair And Fun

Why should you become an AYSO Referee?  We need you.  We can't have games without referees. More importantly, it's rewarding and working with kids is great fun! The referee's job is to be the official in charge of the game. The ref is the independent arbiter and manager of the game. Their authority extends to everyone at the field, including players, substitutes, team officials, spectators, and even assistant referees.
The referee's No. 1 concern is to keep the game as safe as possible for the players. While there is risk in all sports, the referee is responsible for minimizing such risks from field conditions, equipment, spectators, and the players.
The referee is responsible for enforcing the Laws of the Game in such a way as to keep the game safe, fair and fun for everyone: the players, the coaches, the spectators and themselves. The referee interferes with the game as little as possible, avoiding making calls for doubtful and trifling offenses. Referees only make calls for offenses they are sure occurred.

We want our kids to continue to play, and they keep playing as long as it is fun. Referees learn that fun soccer varies from age group to age group of players.

Referee Assignments / Schedules

Referee Scheduler: 
Jim Simpson -- [email protected]

Here are some logistics on how the schedule will be shared for you to volunteer. 

Please follow all guidelines listed in the bullet points below as you sign up for games. 

I will monitor the sheet throughout the week to ensure fairness so everyone has an opportunity to get their volunteer points for their teams, and on Wednesday night, I will send another email reminder that we have moved to the open phase of signups. 

Depending on coverage, I may send out additional emails asking for help on Friday for any urgent needs as we approach the weekend.  I will try to keep the emails shorter each week than this first one that is more informational, but I will include the bullet points for you to follow each week. 

Thank you in advance for your patience and for all of your help as volunteers.

Please adhere to the following guidelines from Sunday through Wednesday night: 

  • Volunteer Points Related: Center Referee will earn 2 points per game. Assistant Referee will earn 1 volunteer point per game (10U-19U Divisions)
  • 19U Divisions Only: 
    • Referee: Only an Advanced or National Referee can serve as Referee
      • Note: May NOT be the Coach, Assistant Coach, parent, or relative of a player on either team

    • Assistant Referee: May be a Regional Referee or above
      • May NOT be the rostered coach or assistant coach of the team, but can be a parent or relative of a player on a team (as a courtesy, the opposing coach should be notified prior to the match but they do not have the right of approval of the Assistant Referee) 
  • 16U Division Only:
    • Referee: Must be an Intermediate Referee or higher to serve as a Referee. 
      Note: The Intermediate Referee working a 16U match must have completed the full Advanced Referee course.
      •  Note: May NOT be the Coach, Assistant Coach, parent, or relative of a player on either team

    • Assistant Referee: May be a Regional Referee or above 
      • May NOT be the rostered coach or assistant coach of the team, but can be a parent or relative of a player on a team (as a courtesy, the opposing coach should be notified prior to the match but they do not have the right of approval of the Assistant Referee) 
  • Please try whenever possible to work with the Head Coach of your team(s) to sign up for games as a Ref Crew of 3 (Center + 2 AR), please avoid signing up for a single slot as this makes it more difficult for a team Ref Crew to sign up for a match
  •  Until Thursday, please only sign up for 1 game to allow volunteers from other teams the chance to sign up and earn volunteer points (exception to this rule is if you have two children on different teams and you are part of 2 different Ref Crews)
  •  Remember that you cannot referee games in the same division as your child's team (ie. your child plays on a 12U Boys team, you cannot referee another 12U Boys match).  Any exception to this rule must be approved by Ref Admin and RC for emergency coverage.

Referee Guidelines

High-Level Guidelines for All Referees

Know the accepted mechanics, signals, and procedures for Referees and Assistant
Youtube is your friend. Here is a video on Referee signals from the Ken Aston Referee Society. 

Referee Signals

* Arrive to the field at Least 20 minutes prior to kick off

* Be professional and approachable yet confident and firm

* Be properly attired with only AYSO approved Referee uniform with socks pulled up & a wristwatch with chronograph capability (timer)

* Take charge but do not dictate

* Always start the game on time

The Referee and ARs should work as a team and never disagree publicly. This one's important for newer Referees. If you're an AR in the match and you'll feel strongly on a call, please do not disagree with the Center Referee at the time of the call. The Center Referee makes the final call at the end of day. Concerns can be brought up as a team during quarter breaks or at the end of a game. 

/// Use sunscreen & maintain hydration before, during half, and after the game

/// Inspect the Field – Goals must be anchored or the game cannot be played

/// Check in the players 10 minutes prior to kick off

/// Introduce yourself to the coaches, be respectful, courteous, and professional

/// Referee should have a pre-game conference with his Assistant Referees

/// Referees (Center) should help mentor new ARS.  Remember that you were a rookie at some point too!

/// Referees should be running, ARs should be running

/// Be decisive and control the game.  Even in 6U/8U.  Tell the players when their behavior is unacceptable.

Coaches should be positive, instructional, and encouraging ONLY.  Be proactive with coaches and let them know that Public, Persistent, Provocative, or Personal actions or words towards any officials will not be tolerated. Ask them to stop. Tell them to stop.

Head Coaches can be cautioned with a Yellow Card. If the Head Coach receives a two cautions or a send-off (Red Card), the Coach will be ejected from the game. In this scenario, the Assistant coach takes over (unless he or she is the one ejected). Contact the RRA for help with a report.

Ask the coach to control problem spectators/parents.  If he or she is unable or unwilling to control parents that are crossing the line, cautions or a send-off will be the end result. Contact the RRA to file a report

Learn from experienced Referees.  Mentoring and peer review is part of soccer officiating.  

Referee Report 
If an incident occurs, whether it's an injury or misconduct related, a referee will need to fill out a Referee Report and turn this report to the Referee Administrator for review.
