Sigma

Sigma Theta Tau International Honor Society of Nursing, today known as Sigma, develops nurse leaders anywhere to improve healthcare everywhere. Sigma’s vision is connected, empowered nurse leaders transforming global healthcare. In 1922, six nurses founded Sigma Theta Tau International Honor Society of Nursing at the Indiana University Training School for Nurses, which is now the Indiana University School of Nursing, in Indianapolis, Indiana. The founders chose the name from the Greek words storgé, tharsos, and timé, meaning love, courage, and honor. Sigma became incorporated in 1985 and is a nonprofit organization. Sigma has more than 135,000 active members in more than 100 countries. From its inception, Sigma has recognized the value of scholarship and excellence in nursing practice. In 1936, Sigma became the first US organization to fund nursing research. Today, Sigma supports these values through its numerous professional development products and services that focus on the core areas of education, leadership, career development, evidence-based nursing, research, and scholarship. These products and services advance the learning and professional development of members and all nurses who strive to improve the health of the world’s people.
