Without rules there would be no games and it is essential that we all know and understand the rules. Umpires are important for ensuring the safety of players and for ensuring that fair play is upheld.

Good umpires maintain respect by being consistent with the standards and are never uncertain. Keep control of the game - use preventative umpiring.
One of the things that annoys coaches and players is when umpires seem unapproachable or detached. You can be excellent with the rules, signalling, using the whistle, and positioning, however unless this is combined with a good rapport with the players, you will have problems.
No matter how long you have been an umpire or how many times you have worked with the same colleague umpire, it is essential you have a pre-match conference before every match.
In order to do a good job as an umpire, you must maintain concentration at all times. To do that you cannot allow anything or anyone to distract you.
