The rules of the game are designed to do two things – promote fair play and keep players safe.
USA Lacrosse is committed to constantly reviewing and updating the rules of the game to ensure that those goals are always satisfied. We write and publish a stand-alone youth rule book for ages 14U and below, and in collaboration with the National Federation of State High School Associations (NFHS), we work together on the rules for boys' high school lacrosse.
