About Theta Tau

Theta Tau is the oldest, largest, and foremost Fraternity for Engineers. Since its founding at the University of Minnesota in 1904, over 30,000 members have been initiated over the years. With emphasis on quality and a strong fraternal bond, the Fraternity has chapters only at ABET accredited schools. Theta Tau carefully follows a program for the selection and development of its members that stresses the importance of high professional ethics and exemplary practices. Within each chapter, the Fraternity stimulates professional activity and social compatibility; provides a framework for group participation in campus, community, engineering, and fraternity affairs; and promotes lasting friendships —a lifetime of brotherhood with fellow engineers.


The purpose of Theta Tau is to develop and maintain a high standard of professional interest among its members, and to unite them in a strong bond of fraternal fellowship.
