This booklet is designed to be a quick reference for persons who are trying to learn the complex game of Girls Lacrosse. It is the continuation of the series of booklets entitled Girls Lacrosse for Spectators that was updated annually. This booklet contains a title change and small changes to the format, but it is basically a continuation of the series. It is for “beginners” because of my perceived need of spectators, coaches, Directors of Athletics, and Umpires to learn the game. This booklet is based on the 2025 NFHS Girls Lacrosse Rules Book, the 2025 NFHS/USAL New Rules Seminars, and the 2025 USAL Officials Training Manual. The booklet is not meant to be exhaustive or comprehensive, but a quick resource and reference before, during, and after games. For more information go to SliderLAX.com.
