Individuals at least 13 years old can sign up to umpire games at the Minors II (9-10 year olds) and Majors (11-12 years old) levels. (Coaches and parents serve as umpires at younger ages, and umpires for older ages must be certified.) After signing up, you will be asked to attend a training session. After completion of the training, you will be able to sign up for games online through the NLL website and will be paid $xx for each game. Sign up HERE.
