Harvard  University is prohibiting professors from having sexual relationships with undergraduates, per a revised Title IX policy.

The new policy announcement comes less than a month after Harvard announced it will be issuing a sexual assault survey during the spring semester, courtesy of the Association of American Universities.

A Harvard spokeswoman told BostInno that the Faculty of Arts and Sciences Committee on Sexual Misconduct Policy and Procedures “determined that the existing language on relationships of unequal status did not explicitly reflect the faculty’s expectations of what constituted an appropriate relationship between undergraduate students and faculty members.”

It added, “Therefore, the Committee revised the policy to include a clear prohibition to better accord with these expectations.”

According to Bloomberg, sexual and romantic relationships between students and professors are discouraged but not explicitly banned. Higher learning institutions like Yale and the University of Connecticut, though, have enacted similar policies. Harvard’s former policy only pertained to a professor whose student is enrolled in his or her class.

Now, “the restrictions apply to lab workers and dissertation advisees” as well, reports Bloomberg.

The idea is that sexual and romantic relationships open up the door for impartial grading on the part of the professor.

Graduate students who grade, supervise or evaluate undergraduate students are also prohibited from engaging in these kinds of relationships. But, as Bloomberg notes, there is no specific punishment outlined in the policy.
