KHO TRAINING: 2-1 OFFICIATING SYSTEM
INTRODUCTION
Advantages of the 2-1 System
-
Hybrid of roles from the 4-Official System and 2-Referee System
-
2 referees to manage the game & maintain standard of play
-
Increased coverage of blue lines over 2-Referee System
-
Improved goal line positioning for referees over 2-Referee System
-
Consistent faceoffs since always conducted by the same official
-
Cost effective for teams; rate benefits to officials
Key Components of the 2-1 System
-
Teamwork: cohesion and coverage as a unit of 3
-
Communication: verbal and non-verbal teamwork
-
Hustle: effort to gain positioning and sightlines
-
Awareness: anticipation of players and partners
REFEREE ROLES
Similarities to the 2-Official System
-
The referees should bracket the play as much as possible
-
The referees generally stay on opposite sides of the ice
-
The referees are rarely both in an end zone together
-
The referees call all goals and must prioritize goal line positioning
-
The referees call call penalties and need to maintain good sightlines
-
The referee (R1) is primarily responsible for blueline calls on zone entry
-
The referees finish potential icing situations (complete or waive)
-
The trailing referee (R2) will conduct all line-change procedures
Differences in the 2-1 System
-
The referees never conduct face-offs
-
The trailing referee (R2) is not on the boards while play is in a zone
-
The referee does not make offsides calls on plays at the top of the zone
-
The trailing referee (R2) skates backwards when the play is leaving a zone
Unique Situations and Variances
-
R1 will "give up" the blue line when the linesman is with the play
-
R2 does cover the blue line when the linesman is in the zone for a face-off
-
R1 and the linesman intervene on scrums/altercations while R2 monitors
-
R1 and R2 are both on the goal line for penalty shots and shootouts
LINESMAN ROLE
Key Responsibilities of the Linesman
-
The linesman conducts all face-offs, including those at center ice
-
The linesman covers the blueline while play is in the attacking zone
-
The linesman stays on the blueline when play transitions out of a zone
-
The linesman initiates all icing situations
-
The linesman escorts penalized players to the penalty box
-
The linesman intervenes on all scrums and altercations

-
The linesman picks up coverage on the blue line once the play is in the zone
-
The linesman stays on the blue line when the play exits an attacking zone
-
The linesman does not leave a blue line until certain play is not going to transition back
Delayed Off-Sides
-
R1 raises the non-whistle hand and points at the blue line with the whistle hand
-
Officials should verbalize "off-sides" to players during all delayed off-sides situations
-
A delay is never "passed off" by R1, but the linesman can join in on the signaling
Icing Situations
-
The linesman initiates a potential icing situation
-
The linesman must verbalize "icing" to players and partners
-
R2 finishes the icing situation by blowing the whistle or waiving the icing
-
R2 retrieves the puck and skates it back to the far end
-
The linesman spots the face-off and is given the puck by R2
-
R2 stays in that zone as the new R1 in the opposite corner from the face-off
-
R1 ensures that no line-change infractions are made during icing situations
-
R1 conducts the line-change procedure on completed icings
-
R1 becomes R2 for the ensuing face-off
