Admission to the Honor Society of Phi Kappa Phi is by invitation only and requires nomination and approval by a chapter in accordance with the bylaws of both the chapter and the national society. Both require superior scholarship and good character as criteria for membership. Phi Kappa Phi is an honor society, not an honorary society or fraternity. Membership is earned; it is a true honor. Meeting Phi Kappa Phi criteria signfies excellence which, in turn, signifies distinction. Because of their outstanding records, members of Phi Kappa Phi often are preferred candidates for grants, scholarships and fellowships for graduate study. When they seek jobs, they find their Phi Kappa Phi membership is widely accepted as an indicator of academic ability and motivation.
To be considered for membership in Phi Kappa Phi, a student must be in the top 10 percent of the senior or graduate class or a second-semester junior in the top 7.5 percent of his/her class. Sound character is a supporting criterion. Faculty and alumni are chosen for outstanding contributions to their fields.
