Roving Umpires have jurisdiction over one or more courts. During a tournament, a Roving Umpire is responsible for ensuring the courts are ready to play, maintaining proper warm-up and rest-period times, resolving scoring disputes, and controlling spectators.

Referees are responsible for making sure that the competition is fair and played under ITF Rules of Tennis and the USTA Regulations. Referees supervise all aspects of play including the conduct of everyone in the competition: players, coaches, parents, spectators, Officials, groundskeepers, and administrative crew.

Chair Umpires are responsible for conducting one match in accordance with the ITF Rules of Tennis and USTA Regulations. During the match, the Chair Umpire is responsible for calling lines when there are no Line Umpires, call the score, record points, games and sets on the scorecard, and make the final decision on every question of fact in the match.

Line Umpires are responsible for calling all shots directed to the lines assigned to them.

Chief Umpires are responsible for scheduling Umpires and organizing court assignment and logistics. At some tournaments, the Referee will delegate the Chief Umpire to appoint and (when necessary) replace or reassign the different Umpires.
