The Honor Society of Nursing, Sigma Theta Tau International provides leadership and scholarship in practice, education and research to enhance the health of all people. We support the learning and professional development of our members who strive to improve nursing care worldwide

In 1922 six nurses founded Sigma Theta Tau 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." The honor society became incorporated in 1985 as Sigma Theta Tau International, Inc., a not-for-profit organization with a 501(c)(3) tax status in the United States.
