10/8/2014
Duties of Referees• Referee’s Job: Keep Game Safe, Fair and Fun
• More specifically: Perform duties stated in Laws 5 and 6 of LOTG
• How? Use principles of Diagonal System of Control (DSC) (modified, when there are fewer than three referees)
10/8/2014
Core Principle of the DSCReferees constantly vary their positions to maximize the likelihood that one is properly situated to judge any event that occurs
– The referee always makes the decision– The assistant referees communicate
(signal) what they have seen, assisting the referee to make a decision
10/8/2014
What Do Officials Need to Monitor?
• Scoring of a goal• Ball over a boundary line• Offside• Fouls/misconduct• Technical infringements (on restarts)

What Governs the Referee’s Movement?
• Where must he be…– To observe what is happening now?– To observe what will happen next?
• These can be contradictory demands!• The assistant referees help resolve the conflict • This is what makes refereeing with fewer than
three officials hard!– Less information from others means more
constraints on positioning– Referee can’t do it all by himself, so must
prioritize10/8/2014
DSC with Two Referees
10/8/2014
DSC with Two Referees• One is the referee, one is an assistant
referee• A club linesman is used on the other touch
line• This is the only acceptable configuration
10/8/2014
The dual system (two referees on the field with whistles) is
not authorized for use in AYSO matches!
DSC with Two Referees: Recruit a Linesman
Why recruit linesmen?– Today’s linesman is tomorrow’s referee
(linesmen are good source of recruits for referee training)
– AYSO is a volunteer organization; volunteers are needed (spectators might need reminding)

DSC with One Referee
• Recruit two club linesman• Never do a game solo without linesmen!
– Physically and mentally taxing– Can’t watch everything– Must focus on priorities: goals, offside,
fouls– Linesmen worry about ball into touch

DSC with One Referee: Implications
• Coverage is shallower and narrower• Judging ball on goal line is next to
impossible• Obvious offside (younger players) is easy• Judging close offside requires being ahead
of the ball at both ends, which is impossible→Don’t call offside unless you are sure!
For older players, tight control is essential→Limit use of advantage

DSC with Fewer than Three Referees: People Management
10/8/2014
DSC with Fewer Than Three Referees:People Management
• Younger players’ games– Focus on the adults– Have pre-game discussion with coaches
• Older players’ games– Focus on players, not coaches/spectators– “Sign up” the players for low offside
expectations– Limit use of advantage– Failure to detect fouls can lead to loss of control
10/8/2014
Fouls Off-the-Ball
• Identify problem players early• Be nearer to problem players• Take a wider position to see more• Ask AR (not club linesman) to watch
players• Speak to players early; prevent escalation• Consider cautioning earlier than usual10/8/2014

When play is here
Summary• Refereeing with fewer than three referees
is a compromise• Use principles of the DSC to adjust position
to compensate• Prioritize your duties and position yourself
to maximize your ability to judge goals, offside and fouls

And remember: the dual system is not authorized for use in AYSO!
