US Lacrosse establishes eligibility guidelines to promote a safe and sportsmanlike environment. US Lacrosse believes that leagues, associations, and other organizers of youth lacrosse should provide playing opportunities that, as much as possible, aim to establish a "level playing field" among players of similar age.

Age and Eligibility Guidelines are not considered “game-day rules” and are not enforced as game-day rules by officials. For specific game-day rules for each of the boys' and girls' age divisions, please visit

NOTE: Age group references used in this section are in common usage but should not be understood literally. The U15 (read: “Under 15”) grouping means that, if a player is 14 years old on the cutoff date, he may participate in U15 competition as a 15-year old.
