The National Collegiate Athletic Association writes the rules for collegiate varsity men’s lacrosse, and those rules are used by the non-varsity Men’s Collegiate Lacrosse Association. US Lacrosse and the NCAA work together frequently on rule development and player safety. US Lacrosse writes the rules for post-collegiate men’s lacrosse.
