The International Order of the Rainbow for Girls (IORG) is a service orientated youth group for girls between the ages of 11 and 20.

 

Local groups (Assemblies) are sponsored by Masonic affiliations. Usually the sponsoring body is either a local Masonic Lodge, Order of the Eastern Star Chapter, Order of the Amaranth Court,

 

White Shrine or a Club composed of members of those previously mentioned. The girls learn about charity, hope, and service through their work and involvement with their annual local and Grand (state or country) service projects.

 

On April 6, 1922, the ceremonies of the International Order of the Rainbow for Girls were first exemplified on a class of one hundred seventy-one girls in the auditorium of the Scottish Rite Temple in McAlester, Oklahoma.
