Non-Skating Officials: NSOs

Non-Skating Officials officiates the game off skates by documenting penalties, managing the game clock and keeping track of general game administration. Below are some of the positions that NSOs run during a game:

  • 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 Tracker: Is responsible for recording the penalties reported by referees and keeps track of the official penalty tally.
  • Penalty Box Timer: Is responsible for timing skater penalties and assisting referees.
  • Scorekeeper: Is responsible for writing down the points reported by the jammer referee and informing the scoreboard operator of the points earned at the end of each jam.
  • Scoreboard Operator: Starts and stops the publicly visible period and jam clocks, and adds points to each team’s score as reported by the scorekeepers. This official also displays which jammer is skating for each team, lead jammer status, and timeout information.
  • Lineup Tracker: Is responsible for recording which skaters are participating in each jam, and which position each skater is playing.
