If you’re interested in NSO-ing, or want to know more, please get in touch on our main email email@example.com, and you will be put in contact with our Head NSO.
Jam Timer The Jam Timer is the most visible NSO in a bout. They start each jam with a whistle, and time the two minutes for a full jam. The Jam Timer also stands on track and indicates a hand signal if either team or the officials call for a time out.

Scorekeepers The Scorekeepers (one for each team) record the points scored by the jammer for each scoring pass. The score is indicated to them with a (very simple!) hand signal from the team’s Jammer Ref.
Scoreboard Operator The Scorekeeper then tells the Scoreboard Operator how many points the team has scored, and they update the official scoreboard (which must be visible to everyone).
Penalty Tracker Penalty tracker records all the skaters’ penalties and when they committed them, using the designated code for each type of penalty.
Inside Whiteboard Records all the penalties for both teams on a whiteboard in the centre of the track. This whiteboard should be visible to both teams’ benches, and the NSOs in the penalty box.
Penalty Timers Time the length of a penalty from when a skater sits down in the penalty box. With ten seconds remaining, they tell the skater to stand, and after the full penalty has been served, they tell the skater that they can return to the track.
Penalty Box Manager As well as a timer for each team, there is usually a Penalty Box Manager who oversees the box and times the penalties for the jammers. They are also able to issue certain penalties to skaters.
Lineup Trackers One Lineup Tracker for each team lists the skaters who are skating in a particular jam.
They also record details such as whether a certain skater sat in the penalty box in that jam, or whether the jam was called off due to injury.
