After potential Referees have had their initial training classes they must be tested under real game situations. Experienced Referees should be present to make notes on the prospects performance. Often, it works well for the teacher to be on the opposit side of the court during a game. After the game the prospect's performance should be reviewed, highlighting good points and explaining faults with suggestions on how to make the necessary corrections. During class sessions prospects should be taught to go through specific routines before each serve, after each volley and when service is lost. They can be any routines that are comfortable for them and are effective.
Some of the most common problems are:
Keeping track of the score - Often caused because they watch the game, not Referee. Or they didn't make notes on how to identify players they don't know.
Keeping track of who is supposed to be serving - They don't constantly check each players' location to make sure it's correct.
Keeping track of First & Second Serves - This is the basic problem of all sorts of errors. They must have an organized way of keeping track of this. Many people use 1 or 2 fingers on top of the clipboard to guide them. There are other ways to do it but they need to be constantly aware of this and using a system that owrks for them. Again, it's often because they are watching the game, not Refereeing.
Missing foot faults - Watching the game again, and not having that as a specific part of their routine.
Additional games should be assigned and reviewed in a similar manner. People who are able to Referee effectively will usually catch their stride after several games. If they do not, and especially if they make the same mistakes repeatedly, it should be explained to them that they would be of more help to the their club in another capacity. If possible, offer another task or tasks that they might consider doing. Make it clear that it's not a matter of intellegence or attitude but that some of us just don't make good Referees.
Special NOTE:
A referee may be removed when both players in Singles or both teams in Doubles agree that the referee assigned to officiate their match is doing a poor job, or at the discretion of the Tournament Director. In the event that a referee removal is requested by only one player or team and not agreed to by the other player or team, then the Tournament Director may accept or reject the request. If a referee is removed, the Tournament Director will appoint the new referee.
