List of tennis umpires

There are three levels of training sanctioned by the International Tennis Federation. After officiating at non-pro events, a chair umpire may enter the "Level 1" program in order to gain a green badge. This is taught in French and/or Spanish and is specifically aimed at officiating in South and Central America and Africa. "Level 2" schools are only taught in English and are for umpires who have already shown proficiency at ITF Pro Circuit events, Davis Cup and Fed Cup ties, and ATP and WTA sanctioned events. It is here that an umpire would receive a white badge. Those chair umpires who pass a "Level 3" school start as a Bronze Badge and can be promoted to Silver and then to Gold following a review of their work rate and performance in the annual review conducted by the ITF, ATP and WTA.
