The Carroll University Nursing Program has the honor of being a chartered chapter of Sigma Theta Tau International (STTI), one of the largest and most prestigious nursing organizations in the world. Chapter chartering entails a rigorous approval process by STTI, including a comprehensive self-study report and site visit. The Tau Mu Chapter received its charter and members were inducted on March 3, 2006.
Students are invited to become members of the honor society during their last semester or if they are a junior levels honor student in the nursing program. Students are inducted based on their GPA or being in the top 35% of their class.
