The Sigma Delta Tau Foundation was founded in 1963 as a separate not-for-profit corporation. The Sigma Delta Tau Foundation is committed to encouraging the growth of its donors, both SDT collegians, alumnae and friends.

The Sigma Delta Tau Foundation supports all members of Sigma Delta Tau by providing financial assistance in the form of scholarships and educational loans and funding educational and leadership opportunities for SDT collegians and alumnae. Decisions are guided by the desire that no deserving, qualified SDT should have to interrupt her education. The Foundation strives to provide every SDT the opportunity to develop personally through participation in educational programs that teach a variety of leadership and life skills.
