Sigma Nursing offers accelerated membership pathway for
Alpha Delta Nu nurses in BSN and graduate programs


INDIANAPOLIS — Sigma Theta Tau International Honor Society of Nursing (Sigma) recently updated its membership guidelines, allowing Alpha Delta Nu Honor Society (Alpha Delta Nu) inductees to be invited to join Sigma at any time during their BSN or graduate nursing program provided they meet all other criteria. The new membership exception guidelines, recently adopted by the Sigma International Board of Directors, may be used at the discretion of each chapter’s governance committee.

This new membership pathway is the latest advancement in an ongoing collaboration between Sigma and the Organization for Associate Degree Nursing (OADN), whose Associate Degree Nursing (ADN) graduates comprise the membership of Alpha Delta Nu. Sigma and OADN previously announced an initiative that provides free resources to Alpha Delta Nu members.

“This Sigma membership pathway recognizes the demonstrated excellence of Alpha Delta Nu members,” said OADN Chief Executive Officer Rick García, PhD, RN, CCM, FAAOHN, FAADN. “I’m delighted to see the continued respect and collaboration between our organizations and among our highly qualified, diverse nursing workforce.”

Sigma CEO Elizabeth Madigan, PhD, RN, FAAN, added, “I am happy to see this accelerated membership pathway reflected in our revised Sigma membership guidelines. This strengthens our collaboration with OADN and Alpha Delta Nu and reflects our mutual commitment to excellence and advancement in nursing.”

To receive an invitation to join Sigma, candidates must meet the following eligibility criteria.*
