Initiate membership is available to every man and woman who is free, at least 18 years old, and of good report (see below). O.T.O. initiations are conferred through a physical ceremony conducted by a chartered initiator. The introductory initiation into O.T.O. is known as the "Minerval" or 0°.

Therefore, the path to becoming an initiate member of O.T.O. involves contacting a nearby or otherwise convenient local body which conducts Minerval initiations (see our Events page), obtaining an application for initiation from that body, and submitting it along with the appropriate dues and fees.

In order to establish "good report", your application must be signed by two sponsors who are already I° initiates of O.T.O. Prospective sponsors will generally want to get to know you before signing your application.

Membership policies:
Privacy: Membership in O.T.O. is private. Names and addresses of members are kept confidential from the general public and from the bulk of O.T.O. members. O.T.O. officers (including local body officers) are provided with information about members on a need-to-know basis.

Non-discrimination: There shall be no consideration of race, ethnicity, sex, gender identity, or sexual orientation when considering the fitness of candidates for admission, advancement, or appointment to office.
