Students become members by joining the chapter at the school where they are enrolled.
Psi Chi chapters are operated by student officers and faculty advisors. Together they select and induct the members and carry out the goals of the Society. All chapters register their inductees at the national office, where the membership records are preserved for reference purposes. The total number of memberships preserved at the national office during the first 65 years is over 270,000. Many of these members have gone an to distinguished careers in psychology.
