The organization has three legislative expressions: local units, the synodical women's organization, and the churchwide women's organization. The organization's highest legislative authority is the Triennial Convention. An elected executive board acts between conventions. The churchwide women's organization staff develops resources, publications, and programmatic services that support the ministries of the synodical and local organizations.

The synodical organizations (located in 64 geographic areas of the U.S. and the Caribbean) are the primary support and encouragement to the local unit. The synodical organizations have within them conferences or clusters that assist as program arms of the synodical organization in this support to local units. While having no legislative authority, the 600 clusters or conferences throughout the organization assist in program delivery and often serve a liaison role between the synodical organization and units.

The local unit is the "member" of the organization. An individual is called a "participant." Each congregation or institution can have one unit; however, each unit may have an infinite number of circles or study groups, action groups, and fellowship groups. Units may use or adapt one of the models for ministry shared on this site as their organizational model or create their own umbrella model that encompasses the ministries, goals, and desires of the women in the congregation(s) or institution.
