Sigma Theta Tau International

The Honor Society for Nursing

In 1922 six nurses founded the Honor Society of Nursing, Sigma Theta Tau International (Sigma) at the Indiana University Training School for Nurses, 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." The honor society became incorporated in 1985 as Sigma Theta Tau International Inc., a nonprofit organization with a 501(c)(3) tax status in the United States.

The mission of Sigma is to support the learning, knowledge, and professional development of nurses committed to making a difference in health worldwide The vision of Sigma is to create a global community of nurses who lead in using knowledge, scholarship, service and learning to improve the health of the world’s people.
