At higher levels of ice hockey competition, three officials – one referee (identified by an orange arm band) and two linesmen – are utilized. At the youth level, two officials – both of whom are referees – are common. The referee is the ultimate authority during the game and is primarily responsible for calling penalties and determining if goals have been legally scored.

The primary responsibilities of the linesmen include conducting face-offs and determining violations of offside and icing while assisting the referee in enforcing the rules of the game.
