Dartmouth College began to admit women students with the freshman class of 1972, which resulted in women members being allowed under current Dartmouth College rules of being accepted to fraternities during the spring semester of 1973. During the winter of 1972/1973, Phi Tau initiated a vote to allow it to become the first coeducational fraternity at Dartmouth College, and to admit women beginning in the spring rush year of 1973. When the organization's constitution was rewritten to reflect the new local status of the brotherhood in 1956, gender references were deliberately excluded from the text, making the house officially coeducational before the college itself. The vote in 1973 formally confirmed the membership policy. Unlike other coeducational Greek houses, members of Phi Tau have continued to refer to one another as "brothers", regardless of their gender. Phi Tau is the only coeducational Greek house at Dartmouth that has always had female members since first admitting them, and was the first fraternity at the College to add sexual preference to its non-discrimination clause.
