List of tennis umpires explained

Listed are current and past tennis chair umpires who hold or have held a gold badge International Tennis Federation (ITF) rating. Gold badge umpires typically officiate Grand Slam, ATP World Tour and WTA Tour matches. The list includes only those who hold or have held a gold badge as a chair umpire, and not those who hold or have held a similar badge in refereeing or chief umpiring. The year, where included, indicates when the umpire obtained his or her respective gold badge status.[1]

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.[2]
