The Department of Education's Office for Civil Rights has added a dozen more colleges and universities to its growing list of institutions being investigated for their handling of sexual assault cases.

The additions bring the total number of colleges included on the list to 67.

In early May, the department took the unprecedented step of publicly naming 55 institutions that investigators are probing to see whether their approach to sexual assault and harassment complies with Title IX of the Education Amendments of 1972, which requires gender equity in education, including proper handling of sexual assault complaints.

“We are making this list available in an effort to bring more transparency to our enforcement work and to foster better public awareness of civil rights,” Catherine E. Lhamon, the assistant education secretary for civil rights, said in a written statement at the time. “We hope this increased transparency will spur community dialogue about this important issue.”

The 12 colleges most recently added to the list are the University of Alaska, Berklee College of Music, Cisco Junior College, Colorado State University, the University of Delaware, Elmira College, James Madison University, Morgan State University, , Missouri University of Science and Technology, the University of Richmond, and Washburn University.

While the list does not contain specific details about the cases, all of the most recent additions are cases opened on or after May 5.
