Often overlooked, the umpire plays an integral part in the Little League experience, as it is he who ensures the game is played properly and fairly. Most Little League umpires have no sons or daughters playing Little League baseball or softball. They volunteer because they love the game and want to give players the best experience possible.

To reach the World Series, umpires must demonstrate expertise at each level of tournament play. Although umpires can officiate in several regional tournaments, umpires cannot work in more than two World Series in their career. Umpires must apply to their region headquarters to be considered for a regional tournament and be endorsed by their district administrator. Once at the regional tournament, umpires are evaluated. Little League uses the evaluations to determine World Series assignments, for which umpires must apply.

As volunteers, World Series umpires must pay their own way to Bangor. Once here, they are provided free room and board.
