A. Massachusetts
Interscholastic Athletic Association 
The Newton North High School Athletic Department is a member of the Massachusetts Interscholastic Athletic Association and is therefore governed by Association Rules and Regulations. Additional policies, regulations and rules are set by the Newton School Committee.
Under MIAA guidelines, local communities are allowed to set their own policy, rules and/or regulations as long as they are more restrictive than stipulated by the MIAA.
Rules governing individual sports vary depending upon the sport. For example, rules are stipulated by the National Collegiate Athletic Association (with MIAA modification) for football, for basketball by the National Federation of State High School Associations, and for baseball by the Sporting News Rules of Baseball. Copies of the complete set of MIAA rules and regulations are available in the athletic office.
One of the primary functions of the MIAA is to sponsor and conduct post-season tournaments leading to the determination of geographical district and state champions. When our varsity teams qualify for and enter such tournaments, we are completely subject to specific rules and regulations that govern each tournament, as set by the MIAA.
Tournament qualification, divisional placement and geographical district criteria are sport specific. Some of our teams may qualify for regional tournaments, beyond the MIAA tournaments, that are sponsored and conducted by the combined state associations that make up the region of competition.
Some of our varsity teams may host and/or play in seasonal tournaments that are sponsored by local school districts or other qualified agencies. MIAA regulations specify that such tournaments be sanctioned by the Association and be conducted totally under their policies, rules and regulations.
The MIAA neither sanctions nor sponsors any sub-varsity tournament competition.
B. Bay
State Conference 
Newton North High School is very proud to be a member of the 12-school league known as the Bay State Conference. The Conference is governed by the MIAA and its own BSC Constitution. A copy of the BSC Constitution is available for your review in the Athletic Office. The Conference sets most of our game schedules at all levels of competition.
Most sport game schedules the Conference sponsors at the varsity level are divided into two divisions for championship play, and for seasonal play at the junior varsity and freshman levels.
The Herget division includes the smaller schools in Dedham, Natick, Walpole, Milton, Norwood and Wellesley. The Carey Division includes the larger schools in Framingham, Needham, Braintree, Brookline, Weymouth and Newton North. Inter-divisional scheduled play is common for most of our teams. We also schedule some non-conference contests against schools from other surrounding communities. A few of our programs such as lacrosse, skiing and boys' gymnastics play in other leagues or compete entirely in a “non-league schedule”. This scheduling occurs because the majority of schools in the Bay State Conference do not sponsor these specific sport activities.
