Society Mission

The mission of the Honor Society of Nursing, Sigma Theta Tau International, is advancing world health and celebrating nursing excellence in scholarship, leadership, and service.

Society Vision 

Sigma Theta Tau International's vision is to be the global organization of choice for nursing.


In 1922, six nurses founded the Honor Society of Nursing, Sigma Theta Tau International (STTI) 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, tharsos, and timé, meaning love, courage, and honor. STTI became incorporated in 1985 as Sigma Theta Tau International Inc., a nonprofit organization with a 501(c)(3) tax status in the United States. Learn more about STTI's founders.
