Founded in 1917 at Cornell University, Sigma Delta Tau (ΣΔΤ) fosters a sisterhood rooted in friendship, leadership, scholarship, and service. With the motto "One Hope of Many People," SDT empowers women to lead purposeful, compassionate lives.

Sigma Delta Tau encourages academic, personal, and social growth, providing a supportive environment for members to reach their potential. The organization is committed to lifelong friendships, leadership development, and community service, particularly through its national philanthropy focused on preventing child abuse. More than a sorority, SDT is a lifelong sisterhood that inspires women to lead with purpose, serve with heart, and support one another through life's challenges.

Sigma Delta Tau has two philanthropies, Child Abuse America and Jewish Women International. Our philanthropies are broken down into two semester of each year. In the Fall our philanthropy is Prevent Child Abuse America. PCAA is an organization that aims to give children the best childhood by preventing abuse and neglect. Through their organization, they promote different services and programs that improve children's well being along with preventing neglect. In the Spring philanthropy is Jewish Women International. JWI is an organization that works to support and empower women through ensuring both their physical safety and economic security. JWI aims to make sure all women thrive economically, in healthy relationships and to their fullest potential.

Legacies bring a unique and special bond to our sisterhood, connecting generations of family ties. A Sigma Delta Tau legacy is a sister, daughter, granddaughter, great-granddaughter, or step-relative (such as a stepsister or stepdaughter) of an active member or alumna. A sitting sister legacy has a sister who is a current active member of the chapter.

Sigma Delta Tau chapters understand the importance of legacies and how their heritage strengthens the sisterhood. While legacies are given special consideration during recruitment, membership is not guaranteed due to the high number of legacies participating. Legacy forms can be submitted on the SDT website.
