The NLLB umpire program is designed to start umpires off at the Rookie levels (1st and 2nd grade baseball) and allow them to naturally progress to higher levels.
A child must be 12 years old by August 31, 2025 to umpire for Naperville Little League Baseball. Please do not register your child as an umpire if they are not 12 years old by 8/31/2025. ALL NLLB umpires must create and maintain an updated profile via the NLLB website. This profile tells us about you, your experience, provides contact information for game opportunities, important communications, and tells us where to send your paycheck.
All umpires who will be 18 years of age and older prior to October 31, 2025 must complete volunteer registration and submit to a background check. Click here to complete volunteer registration.
Umpires are required to attend training in order to umpire with NLLB. Click here for training dates and further information about becoming a NLLB Umpire.
