Class V organizations make up the third tier in the structure. They are authorized to offer auditing and training up to the level of Clear. They supervise the activities of field auditors and missions, and provide basic training for ministers, as well as being centres for other types of ritual and community service mentioned under previous headings. Class V organizations provide the core of the day-to-day ministries offered by the Church of Scientology.
In four major centres around the world there are higher level churches
which offer more advanced Scientology auditing and training services. Persons
participating in these programs typically do so on an intensive, full-time
basis, very often with the expectation of continuing to serve as ministers
within the Church of Scientology after returning to the local Scientology
churches from which they have come.
