About Sigma Tau Delta Membership
Membership in Sigma Tau Delta is by invitation, extended through a local chapter on behalf of the international organization. Students who qualify for membership must apply through the chapter on their campus. Once a student contacts the local chapter, the advisor will check the qualifications and, if approved, recommend that student for membership.
