 The headquarters of the international organization moves to a different country every four years.Each level of the association has members called "helpers" whose role is to coordinate the timing of group latihan, witness the opening of new members, speak to those interested in the latihan, be available to discuss problems relating to the latihan, and sometimes attend to the latihan needs of isolated or indisposed Subud members.Helpers are usually selected from members who are willing to perform the duties, and selection generally occurs through testing.
