The Vassar College Exchange Program took place during the 1969 school year and served as a way to introduce both Trinity and Vassar Colleges to becoming coeducational.

Trinity, at the time a men's college, exchanged students with Vassar College, an institution in New York that was a women's college until 1969.

Trinity students had to pass and be selected from an application process in order to be accepted to the one-semester-long exchange, and were expected to keep up a five-class course load while at Vassar. The 25 selected Vassar girls at Trinity were reportedly treated equitably to the male studentes, being held to the same rules and granted the same privileges (such as being allowed a car on campus). They were placed on the second floor of the North Campus dormitory.

The need for the program lessened after Trinity officially became coeducational in 1970, and was only implemented in the spring and fall semesters of 1969.

Reactions of participants from each side of the exchange can be found below in the 1969 Alumni Magazine. Both colleges, though for differing reasons, believed that the program fostered change within the colleges and that coeducation was possible.
