 An active member of the fraternity is a full-time enrolled student at his chapter's host institution at the undergraduate, graduate, or post-graduate level; all others, including members who have graduated or transfer to a school without a Phi Psi chapter, are considered alumni.Men may be initiated into Phi Kappa Psi either by an active chapter, or as part of a colony that is being installed as a chapter.Members typically join Phi Kappa Psi when a chapter extends an offer to enter into a probationary period known as pledgeship, which within the organization, and per National guidelines lasts no more than 6 weeks and concludes with initiation.
