The important role that local trainers play in the overall growth, development and quality of officiating is something US Lacrosse recognizes and hopes to provide expanding support for.

All officials, as part of their annual US Lacrosse Certification, are required to attend and complete annual learning requirements. This education and development is typically conducted locally and led by local experienced officials tasked with training the officials in their area.

As the sport continues to grow, the need for trainers to conduct annual training of officials grows as well. US Lacrosse, through this program hopes to standardize the requirements for trainers at the local level by providing additional support and development opportunities tailored to them to increase the quality and consistency of training throughout the country.


Applications are reviewed by US Lacrosse Officials Development  as well as US Lacrosse Regional Managers. 


Applications for the Trainer Certification Program are now closed. Applications will reopen in the fall.

Trainer Certification

The goal of this program is to develop trainers, by utilizing online resources emphasizing proper mechanics, correct rule interpretation, and showcasing different methods of engaging learners; while providing trainers with resources to enhance their training classes. As such, Certified Trainers will be trained to communicate and work with officials at all levels of play, and will be tasked with reporting training data to US Lacrosse.


Applications are now closed.  Trainer Certification applications for 2022 will open in the fall. 


Interested applicants should be:

  • An official with at least three years of officiating experience at the high school level in their area
