The NLLB umpire program is designed to start umpires off at the Rookie levels (1st/2nd grade baseball) and allow them to 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. Umpires under the age of 18 must be registered by a parent.
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 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.
