Skating Officials: Referees

Head NSO: Is responsible for all the NSOs during a game. They print and distribute the official paperwork, help the other NSOs during the game, and gather the paperwork at the end of the game.

Jam Timer: Is responsible for starting each jam, stopping jams if they run the full two minutes, maintaining the period clock, making sure the scoreboard clock is in sync with their clock, and signalling and timing official reviews and team timeouts.

Penalty Trackers: Is responsible for recording the penalties reported by referees and keeps track of the official penalty tally.
