The New Jersey State Interscholastic Athletic Association (NJSIAA) is an association of hundreds of New Jersey high schools that regulates high school athletics and holds tournaments and crowns champions in high school sports. State championships In order for schools to move on to the state championship, they must achieve a winning percentage of .500 or greater by a pre-set date (the "cut–off" date). Football, wrestling and bowling are the only sports where a school may have a .500 record and not qualify for the postseason. For football and wrestling, it is only the best eight schools in each section that move on. This is determined by power points, awarded to each game's winning team and based on the size of the school that is defeated and the score of the game. Winning percentage alone, however, is not sufficient to qualify for the playoffs. If a school's team has too many disqualifications, it is disqualified from the state championship. In bowling the top 2 teams in each division (North I, Group I; North I Group II, etc.) in the State Sectional Tournament, qualify for State Finals. When a team wins its sectional championship, it is awarded a blue trophy on which is noted the section and the sport. For public schools, the two North Jersey winners face off against one another, while the South and Central teams play each other in the statewide semi-finals. The two winning teams then play each other for the statewide Group championship. For non-public schools, the two section winners compete in the state Non-Public championship; the champion receives a gold trophy. For some sports, each group's state champion play each other in the Tournament of Champions for the overall state championship and #1 state ranking. For boys, the tournament is offered in basketball, bowling, cross country, golf, lacrosse, tennis, track-indoor, track-outdoor, and volleyball. For girls, the sports are basketball, bowling, cross country, field hockey, lacrosse, tennis, indoor and outdoor track, and volleyball. In some sports, there are no group championships. In these sports — all schools, public and non-public alike — compete for a single state championship. For boys, the sports are fencing and golf. For girls, they are fencing, golf, and gymnastics. Student athletes may also be state champions. The sports that offer individual state championships are bowling, cross country, fencing, golf, gymnastics, tennis (singles and doubles), swimming, diving, indoor and outdoor track, and wrestling.
