Tau Sigma Delta (ΤΣΔ) is an American scholastic honor society that recognizes academic achievement among students in the field of architecture and allied arts.[1]


Tau Sigma Delta was organized at the University of Michigan as an honorary fraternity in architecture and landscape design in May 1913, at the proposal and under the direction of the faculty members of the Departments of Architecture and Landscape Design at the University of Michigan. It was first known as Tau Delta Sigma and continued under that name until the fall of 1914 when it was decided to change the name to the present one there being Greek letter societies already bearing the first name. It was the intention of the founders that the organization should be a national society as opportunity for its extension to other schools and universities could be had.[2]

As of 1920 according to the Constitution of Tau Sigma Delta, the purpose of the society is stated as follows: "It shall be the purpose of Tau Sigma Delta fraternity to unite in a firm bond of friendship, such students of architecture and the allied arts, whose marked scholastic ability, moral character and pleasing personality has shown them worthy of distinction, and to foster and promote high standards of study in the schools and colleges of architecture and the allied arts." The society is a purely honorary organization, and only a very limited number of new members are elected each year.

Each chapter has a definite plan of government and elects its members who are chosen only upon the approval of the faculty of the school at which the chapter is located.

A series of medals are available as awards for achievement, in bronze, silver and gold.
