Missouri Rainbow Assemblies have regular meetings twice a month on a set schedule, as well as service projects, fun activities and fund raisers. The youth leader is called the “Worthy Advisor” who presides over the meetings where the girls attend to business and the workings of the Assembly; and perform memorized work. The girls themselves, with the guidance of their Advisory Board, are responsible for the financial management, correspondence, and organization of all assembly activities.
An assembly has elected and appointed offices. Every 4 to 6 months, an Installation of officers is held and is open for all to attend. Girls are given the opportunity to fill many different positions for a short period of time. A girl may wish to advance through the elected offices and eventually become the Worthy Advisor. Any member may accept chairmanship of an event or committee, learning to organize and work with peers to a successful conclusion.
The Advisory Board is comprised of Majority Members, member’s Parents, Grandparents, and Legal Guardians, Master Masons, members of Eastern Star, Amaranth, or White Shrine. These adults have a deep interest in helping young people, are respected leaders, and provide the core of the directly involved adult leadership.
A Mother Advisor is selected from among the members of the Advisory Board. She works hand-in-hand with the girls and allows them to preside over the affairs of the Assembly with her direction and guidance.
There are also statewide meetings, held throughout the year as well as the state convention called “Grand Assembly”. Every two years an international meeting called “Supreme Assembly” is held.
