New Jersey State Interscholastic Athletic Association - Lacrosse

The New Jersey State Interscholastic Athletic Association (NJSIAA) governs boys’ and girls’ high-school lacrosse in New Jersey, including regular-season regulations, classifications, tournament administration and state championship history. Its 2026 programme operated separate public and non-public tournaments, with public sectional and group finals and a non-public state final. Qualification used a PowerPoint ranking system, while official rules, tournament procedures and officiating resources were published for both divisions.
