The National Federation of State High School Associations (NFHS) authors rules for high school boys’ lacrosse, and those rules govern youth boys’ lacrosse except where US Lacrosse has amended otherwise. Those amendments are based in part on exhaustive surveys of rules in leagues representing nearly 170,000 youth players and on research and published literature from the US Lacrosse Sports Science and Safety Committee, resulting in the development of age-appropriate playing rules and the annual publication of the “Youth Rules and Best Practices Guidebook for Boys.”
