Membership is established and maintained by payment of the annual prescribed membership fee through a local parish council. Four categories of membership are available:

  1. General Membership: a Catholic woman 16 years of age or over, may become a member, with voting privileges and with eligibility for office by election or appointment.
  2. Life Membership: a member, nominated by a diocesan or provincial council, fulfilling the criteria established by the national executive, may be awarded a life membership in national council.
  3. Honorary Life Membership: a distinctive honour bestowed on a member who has served as national president.
  4. Associate Membership: a non-Catholic woman 16 years of age or over may become a member, with voting privileges, but without eligibility for office by election or appointment.
