As a member-led organization, the schools that make up the NMAA are responsible for the creation and adjustment of rules as listed in the NMAA Handbook. The Board of Directors authorizes proposals (referenda) for amendments to the Constitution, Bylaws, and Sports Regulations. These referenda items are then voted upon by the NMAA membership. A referendum requires a favor/do not favor response by the official voter in schools which are affected by the issue in question. All ballots must also be signed by the superintendent/headmaster.
