Michelle Issadore, Campus sexual assault expert
The short answer is that the Department of Education's Office for Civil Rights issued a Dear Colleague Letter in April of 2011, clarifying their stance that sexual assault amounted to a form of gender discrimination under Title IX. That sparked a climate in which Title IX coordinators, deputies, and investigators, as well as Human Resources, advocates, police, student conduct officers, and more needed to learn more and adjust their prevention and response on this issue. Additionally, student activists championed the cause and brought additional awareness to the issue. The media has paid much more attention to campus sexual assault, as well, in recent years.
