How to Join a Secret Society: Membership Requirements

Membership in fraternal and secret societies is rarely open to walk-in applicants. Most established organizations operate through structured invitation, sponsorship, or petition processes that filter candidates before any formal vote occurs. Understanding how these mechanisms work — and how requirements differ between elite collegiate societies, philanthropic lodges, and fraternal orders — is the foundation for anyone researching whether or how to pursue membership.

Definition and scope

Secret and fraternal societies occupy a broad institutional spectrum. At one end sit highly selective organizations like Skull and Bones at Yale University, which taps exactly 15 new members per year from the senior class through a process called "Tap Day." At the other end are membership-driven fraternal orders like the Odd Fellows, formally the Independent Order of Odd Fellows (IOOF), which welcomes petitioners who meet basic eligibility criteria and receive a sponsor's endorsement.

The Fraternal Information and Service Center, maintained by the Fraternal Alliance (formerly the National Fraternal Congress of America), documents the general governance structures under which most recognized fraternal bodies in the United States operate. These structures share a common principle: membership is a formal status, not a consumer relationship, and it is governed by bylaws that carry legal standing within the organization.

For a broader orientation to how these organizations are classified and what distinguishes them from one another, the overview at the index provides a working taxonomy of the societies covered across this reference property.

How it works

Membership entry in most documented societies follows a defined sequence of phases, not a single application event. The typical pathway involves 5 discrete stages:

1. Identification or self-nomination — The candidate either receives an invitation from current members or identifies a lodge or chapter accepting petitions.
2. Sponsorship — A current member in good standing agrees to vouch for the candidate. In Freemasonry, as documented by the Grand Lodge of Massachusetts, a petitioner must be personally recommended by at least 2 Master Masons.
3. Petition or application — The candidate submits a written petition, which may require biographical information, professional references, and an affirmation of belief in a Supreme Being (required by Freemasonry and several derivate orders).
4. Investigation — A formal committee of lodge members reviews the petition, often conducting interviews with the applicant and their references. This stage can span 30 to 90 days in typical Masonic practice.
5. Ballot — Members vote by secret ballot. In many orders, a single negative vote ("blackball") is sufficient to reject a petition, though some bodies require 3 negative votes before rejection stands.

The degrees and ranks system is a parallel structure that governs advancement after initial admission, not the entry process itself.

Common scenarios

Masonic lodges represent the largest category of active fraternal societies in the United States, with the Grand Lodge of the District of Columbia and comparable state bodies publishing publicly accessible petitioning guidelines. The stated eligibility floor across most U.S. grand lodges is: male, at least 18 years of age, a belief in a Supreme Being, and no prior felony conviction. Costs vary by jurisdiction, but initiation fees frequently fall between $100 and $400, with annual dues averaging $100 to $200 depending on the lodge.

Knights of Columbus, documented through the organization's own public membership portal at kofc.org, restricts membership to practicing Catholic men aged 18 or older. With over 2 million members across 16,000+ councils globally, the Knights represent one of the highest-volume fraternal recruitment models in operation, relying on parish-level sponsorship rather than invitation-only selection.

Collegiate societies such as Skull and Bones or Harvard's Porcellian Club use invitation-only models that preclude self-nomination entirely. Candidacy is controlled exclusively by existing members, making these structures fundamentally different from petition-based orders.

Professional networks with fraternal characteristics — including certain legal, medical, and business fraternities — typically require credential verification as a primary filter. Phi Delta Phi, the international legal honor society founded in 1869, requires law school enrollment at an affiliated institution and a minimum GPA threshold that varies by chapter.

Decision boundaries

Not all organizations that describe themselves as secret societies operate membership systems with meaningful transparency. Three classification boundaries determine whether a given organization's membership process is navigable:

Open petition vs. closed invitation — Orders that publish bylaws and accept written petitions (Freemasonry, Knights of Columbus, Shriners International) are categorically accessible to qualifying candidates. Organizations that select members entirely through existing member networks (Skull and Bones, Bohemian Grove) offer no entry pathway independent of social proximity to current members.

Age and credential thresholds — Most fraternal orders set a hard minimum age of 18. Collegiate societies restrict eligibility by enrollment status, meaning the eligibility window closes at graduation. Professional fraternities impose academic or licensure criteria that eliminate non-qualifying applicants regardless of social connections.

Religious and moral declarations — Freemasonry's requirement of belief in a Supreme Being excludes declared atheists, a policy affirmed by the United Grand Lodge of England's published constitutions. The Knights of Columbus restricts membership to practicing Catholics by definition. Organizations without doctrinal requirements — including the Rosicrucians of the Ancient and Mystical Order Rosae Crucis (AMORC) — accept members through direct online application without religious screening.

Understanding oaths and pledges that accompany admission is a legally and ethically relevant step before submitting any petition, as these commitments carry organizational consequences even when they lack civil legal force.
