2 Referee/2 Linesman
Two Referee / One Linesman
Most Common for ACHA D-III games.
Objectives: •Obtain better sight lines of potential penalty situations•Additional set of penalty-calling eyes•Minimize disruptions to play and deter potential penalties by elevating the noticeable level of oversight
Two Referee / One Linesman
•Referees still call goals and assists, penalties, and conduct line changes, and move in tandem, just as the two official system.•Most important aspects are to stay out of play and to constantly attempt to improve sight lines•When a referee assesses a penalty, his counterpart should escort the player to the penalty box. •The nearest referee should assist the linesman in separating any gatherings of players while the back referee (who will have a greater field of vision) should observe, record, and assess infractions as they may occur.•Referees will complete all icings and may make occasional offside calls.
Two Referee / One Linesman
•When play is in the neutral zone, the linesman should maintain a position on the center red line. The referees are responsible for the first onside/offside calls.•Once play has moved into the zone and/or in a definitive direction, the linesman should assume the blue line.•As soon as play begins to transition the other direction, the back referee shall assume position on the opposite blue line.•Referees making onside/offside calls are discouraged from making visual signals (but are encouraged to verbalize)
Two Referee / One Linesman
Rules of Thumb•Added communication and teamwork are vital.•Referees making onside/off side calls should verbalize but not visually signal except in case of closer calls.•High referee assists the linesman in separating any gatherings of players.•If the low referee transitions behind the net, the referees should endeavor to eventually rebalance their sight lines.•Whenever possible the referee not calling a penalty or conducting a line change should obtain the puck for the linesman while observing all players.

SCRUM
If One Player is Penalized:•Referee assisting linesman escorts penalized player and then conducts the line change•Linesman marks the faceoff spot •Other Referee Assesses the penalty and then goes to the end in which the faceoff will take place.

Two Referees / Two Linesmen
Rules of Thumb•Like the two-one system, requires flexibility, cooperation, and respect; also aims to achieve ideal sight lines.•Either referee may cross to opposite side of ice but both must work together as a team.•Two referees on the same side of the ice is not an issue, however one should transition to the opposite side when an opportunity presents itself.•Front / Lead referee should be positioned close to the action area (which is his first priority). •Back referee should be between blue and red lines (and maintain a greater field of vision).
Two Referees / Two Linesmen
Rules of Thumb•Communication and mutual respect are vital to the success of the 2R+2L system.•Both referees have the authority to make any appropriate call, anywhere on the ice surface.•Officials should never make negative comments or allow body language to suggest disapproval of a fellow officials call or non-call. Nor should one referee ever lay blame on a fellow referee.•Avoid “washout” signals, as they can be dangerous.•Remain open to consulting with the linesmen.
Guiding Principals (All Systems)
•Referee must always stay “with play” and should always be positioned at the net for goal situations.•Maintaining an ideal field of vision is a key objective regardless of the system utilized or one’s role within such system.•Teamwork and communication are vital. Regardless of how many referees or how many linesmen there are, respect your peers and their experiences.•Awareness of one’s partners’ positioning is also vital. Should a second referee need to transition behind the net, as soon as is practicable, one of the two should transition to the other side.
