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, at the Indiana University Training School for Nurses, now the Indiana University School of Nursing, in Indianapolis, Ind., 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.


STTI membership is by invitation to baccalaureate and graduate nursing students who demonstrate excellence in scholarship and to nurse leaders exhibiting exceptional achievements in nursing. Here are some additional facts about our membership:
