It is one of the so-called "super conferences" created by the New Jersey State Interscholastic Athletic Association (NJSIAA) as a part of a realignment of high school sports leagues in North and Central New Jersey announced in 2009.
[3] Increasing conflict over competitive imbalance in New Jersey high school sports leagues led to the formation of a committee to study the issue in 2008.
