Membership in the Honor Society of Phi Kappa Phi is initiated by the chapter, which will distribute invitations each semester to students whose GPAs qualify them academically to join. For undergraduate students, the top 10% of seniors and the top 7.5% of juniors are invited each fall. For graduate students, the top 10% of students are invited.
If you have received an invitation to join, then congratulations! "It means that you are among the very best and brightest that your university has to offer—not just in your chosen field of study, but among all academic disciplines."
With your invitation in hand, visit the national society's site to complete your membership online.
Thanks for your interest! Contact the chapter if you need more information.
