Although Tau Beta Pi never discriminated on the basis of race or religion, Tau Beta Pi did make its start as a male-only society. Female engineering students were scholastically eligible for Tau Beta Pi as early as 1902; however, those women were not granted membership. Starting in 1936, TBP awarded a "women's badge" to exceptional female engineering students, and a total of 619 women's badges were awarded until 1969. In 1969, Tau Beta Pi began granting women full membership in the society.
