Here's what the WFTDA Rule Book tells us:
Here's the Casebook:
Non-Skating Officials - NSOs
NSO positions include:
Jam Timer - At a bout, the jam timer times and starts jams, tracks the 30 seconds between jams, and ends a jam at 2 minutes.
Penalty Tracker - During a bout, the penalty tracker records the penalties called by referees and keeps track of all the penalties.
Penalty Timer - At every bout, there are at least 2 officials overseeing the penalty box, who keep track of the skater's 30 second penalties and release the skaters back into play.
Score Catcher - 2 scorekeepers are needed for each game. They record the points reported by the Jammer Referees and keep the official score.
Scoreboard Operator - 1 scoreboard operator is needed to work with the computer scoreboard system and input the scores from the scorekeepers as well as ensures that the game clock is running correctly.
