The National Federation of State High School Associations (NFHS) authors rules for high school boys’ lacrosse. For 2017, US Lacrosse has produced a stand-alone youth rule book for ages 14U and below. The rule sets in this book align with the principles of the Lacrosse Athlete Development Model (LADM), helping to ensure age-appropriate rules that allow athletes to progress and reach their maximum potential. In 2017, US Lacrosse also developed a rule set to govern box lacrosse.
