NOMAS is committed to supporting local chapters. According to the NOMAS bylaws, four NOMAS members are needed to found a new chapter. The local group sends membership dues to the national office. The local chapter may also add additional fees as it sees fit. The national office, in turn, supports the local group with materials, contact lists, publicity and financial support. Membership starts at $15, but can be waved for financial hardship. NOMAS chapters organize their own programs and are trusted to abide and uphold the NOMAS "Statement of Principles" and Tenets. Member chapters and affiliates report to the national council at least twice a year on local activities and programs.
