Refs and NSOs
Roller Derby needs Refs and NSOs
Refs have the best view of the game. Refs are on skates calling penalties and assigning points. It’s a great way to be involved without being in the bout. A fully staffed game requires 2 Jam Refs plus inside pack refs (IPR) and outside pack refs (OPR). One of the refs is the head referee.
NSOs keep the bout going! A small army of NSOs is required for each bout, performing scorekeeping, penalty box timing, jam timing, or tracking lineups and given penalties.

Collision can train refs and NSOs!
You can skate with us, or not!
