All officials must attend a play day and annually be re-certified. Junior officials must attend a youth play day. Returning adult officials must attend a CIF/High School and youth level play day (4 hrs each). New adult officials have the option to attend a youth play day or a HS play day. In all cases the official who is in training will be with an experienced official on the field and the event will be under the supervision of a USA Lacrosse Certified Trainer or Evaluator. 

Due to the limited number of play days and USA Lacrosse Certified Trainers and Evaluators, officials will be assigned to play day locations by the Training Committee. Officials MUST be available the entire day, although they will only be scheduled for a 4-5 hour block of time. Should a schedule conflict arise please email assignor2@ncwlo.org and a member of the training committee will connect with you.
