MRRS assigns referees for matches within Montana, northern Idaho, and eastern Washington. The organization attempts to assign referees of sufficient skill to each match to allow for a safe, fair match and to allow referees and players to develop. Match appointments are seasonal:
Before each season, the MRRS allocators send out a request for games to be assigned and include a deadline. If requests arrive after the deadline, the MRRS will attempt to fulfill the desire for a referee as best as possible.
