Minor League Baseball Umpire Development

Minor League Baseball Umpire Development is the entity which is responsible for the training, evaluation, and recommendation for promotion, retention, or release of all umpires in the Minor League Baseball system throughout the United States and Canada. Minor League Baseball Umpire Development is a wholly owned subsidiary of the National Association of Professional Baseball Leagues (NAPBL).

At mid-season and end of each year, an evaluation is written by the staff on every Minor League umpire. The umpire's evaluations are based on performance during the year and are used by the Minor League presidents to determine whether or not the umpire will advance in classification the following season.

Each year in February, Minor League Baseball Umpire Development holds its annual Advanced Course, where prospective rookie umpires are invited for instruction and evaluation of their umpiring abilities. The students who rank the highest at the Advanced Course are recommended for the first openings in the Rookie and Short-A leagues each year, thereby beginning their careers in professional baseball.

The job of a professional baseball umpire requires quick thinking, common sense, and confidence. When the ball is in play, the umpire sees the action, assesses the situation and makes the call -- all in a matter of seconds. The successful umpire has a thorough knowledge of the rulebook, is even-tempered, and is mentally strong enough to handle situations under stressful conditions. A professional umpire is expected to hustle, be alert, be in excellent physical condition, and have a neat appearance.

Each year Minor League Baseball Umpire Development recommends new candidates to serve as umpires for Minor League Baseball. These candidates have good training, strong ability as umpires, and a keen desire to succeed.

Umpires seeking a job in professional baseball must meet some basic requirements. Each applicant must have:

  • High School diploma or G.E.D.
  • Reasonable body weight
  • 20/20 vision (with or without glasses or contact lenses)
  • Good communication skills
  • Quick reflexes and good coordination
  • Some athletic ability
  • Required preliminary training for the job (i.e., professional umpire school)
  • A driving record that makes him or her insurable and able to drive employer-provided transportation

The first step to pursuing a career as a professional umpire is to attend a professional umpire training school. These schools traditionally run for a period of four-five weeks during January and February each year. At the end of the training, the schools recommend their top graduates to the Minor League Baseball Umpire Development staff. Minor League Baseball Umpire Development then extends a formal invitation to participate and compete at the Minor League Baseball Advanced Course to those graduates who meet the requirements and criteria. Graduation from one of these schools does not guarantee an invitation to the Advanced Course or a job in Minor League Baseball.

During the Minor League Baseball Advanced Course, each umpire's performance and abilities are evaluated by the Minor League Baseball Umpire Development staff. At the conclusion of the course the students are ranked, based on performance, and recommendations are then made to the Minor League Presidents regarding additions to their umpire staffs.

Those selected from the Advanced Course will start their careers in either a Rookie or Short-A Minor League. While progressing from Class A to Class Double-A to Class Triple-A leagues, the umpire receives valuable training and experience which may provide an opportunity to become a Major League umpire. It usually takes seven to eight years of umpiring professional baseball at the Minor League level before the umpire is considered for a position at the Major League level.

In order to be considered for a professional umpiring position, the umpire must first attend a professional umpire training school. 

The Minor League Baseball Umpire Training Academy operates for approximately four weeks from the first part of January through the first part of February each year. The instructors at the Academy consist of Minor League Baseball Umpire Development Field Evaluators/Instructors. 

The Harry Wendelstedt School for Umpires operates for approximately five weeks from the first part of January through the first part of February each year.
