A year later, the first male students were admitted, making the college fully coeducational.

In the late 1970s, Edgecliff developed an articulation agreement with the Cincinnati College of Mortuary Science, which allowed CCMS students to receive their Bachelor's degree at Edgecliff after receiving their diploma and Associate's degree from CCMS.

Following financial struggles, Edgecliff officially merged with Xavier University on July 1, 1980.

All student records are now held by Xavier, and services for the more than 3,500 living alumni are organized through the university.

In 1977, several of the buildings were listed on the National Register of Historic Places for their architecture, and the Edgecliff House itself was individually granted the same designation in 1980;[1] it has since been demolished.
