How to Become a College Umpire
Have an interest and, preferably, experience playing baseball. If you never played, though, it doesn't disqualify you from becoming an umpire. There is, however, a nuance and feel to the game that you only pick up by playing. That intangible translates to your work as an umpire.
Gain experience. Many umpires start in youth baseball and move up to the high school level. Once they feel comfortable behind the plate, they start looking for college jobs. The Collegiate Baseball Umpires Association of New England, which provides umpires for nearly 100 colleges in New England, requires its members to have five years of high school varsity experience and to be an active member of an accredited high school umpires board.
Know the rules by heart. The college level isn't a place for umpires to be learning on the spot. You'll likely have to take a written NCAA rules test and on-field mechanics test.
Get recommended by umpires who already work in the conference or association where you're trying to get hired. Some associations require two or three recommendations.
Attend umpire clinics. Professional umpires give seminars and training at clinics. You'll pick up tips and get to meet other umpires.
Network with established umpires. This is one way to get recommendations in the future. You could meet umpires at clinics, or simply approach them after a college game. Then, keep in touch with them. It's a good chance someone will take an interest in you.
Contact collegiate umpiring associations or college conferences. Let the board of directors know you're interested in one day becoming a college umpire. Keep them updated on your career.
