The Department of Education has launched an investigation into Title IX compliance at Dartmouth on its own accord, The Dartmouth  reported on Tuesday.

The investigation — which was not prompted by a complainant — opened in May, the same month that a group of more than 30 Dartmouth students and alumni filed a complaint alleging the college had not adhered to Clery Act regulations regarding the tracking and disclosure of campus crimes, including sex offenses. Students and alumni involved said they had also been interested in filing a Title IX complaint, according to The Dartmouth.

The Department of Education has not provided a reason for why a Title IX investigation was opened, according to Bloomberg.

In the past year, a growing number of universities — including Occidental College, Swarthmore College and the University of North Carolina — have come under DOE scrutiny for violating Title IX regulations regarding  sexual misconduct resources.

The DOE’s Title IX investigation of Yale concluded after a 15-month investigation in 2012. The University entered a voluntary resolution agreement with the DOE’s Office for Civil Rights (OCR), in which it agreed to uphold its sexual misconduct prevention and response programs and report regularly to the OCR. Over the course of its investigation, the OCR found that Yale had underreported incidents of sexual harassment and violence and did not effectively inform students of sexual misconduct resources.

In April, Yale was fined $155,000 for failing to adhere to Clery Act reporting standards for campus crime, including four instances of sex offense. According to Bloomberg, the DOE has also launched a Title IX investigation at the University of Southern California.
