Regions sponsor local conventions and assemblies. Regional assemblies also nominate trustee candidates to serve on OA’s Board of Trustees (BOT), whose members are elected at the World Service Business Conference (WSBC).
Two or more groups can form an intergroup (IG). The intergroup provides services to existing groups within its geographical area and spreads the OA message of recovery to those who still suffer.
A group consists of two or more people. Each group practices the Twelve Steps and Twelve Traditions of OA.
No member of a group is required to practice any actions to remain an OA member or to have a voice at a meeting.
