Typically, CoDA meetings begin with introductions and readings from the CoDA preamble and lead into a group sharing session, which is then closed with a prayer, explains CoDA.org. Most CoDA chapters follow a basic format, although the specifics of the format differ by chapter.
Some chapters begin meetings by reading the Welcome, Twelve Steps, or Twelve Traditions in place of the preamble, according to CoDA.org. It is not required to speak during the introduction or group sharing session. Prior to the closing prayer, some chapters encourage members to list their first name and phone number on the group sign up sheet, but this is usually optional.
