Strategic Goals

The Sigma board of directors has determined four strategic goals to guide the organization:

  3. Expand and develop strategic relationships globally
  4. Advance innovative and customized resources to develop nurse leaders


In 1922, six nurses founded Sigma Theta Tau International Honor Society of Nursing, today known as Sigma, at the Indiana University Training School for Nurses, which is now the Indiana University School of Nursing, in Indianapolis, Indiana, USA. The founders chose the name from the Greek words storgé, thárros, and timé, meaning love, courage, and honor. Sigma became incorporated in 1985 and is a nonprofit organization with a 501(c)(3) tax status in the United States.

Formed on Apr 17, 1994, Xi Delta Chapter is the 338th chapter established at Sigma Theta Tau International Honor Society of Nursing.

Please join us on 4/12 for our first inaugural Department of Nursing and Xi Delta Research Day. RSVP by 4/1.
