The College Board says it has approved a new policy that prohibits students from wearing certain “blackface” outfits on campus

NEW YORK — The College Fund, a nonprofit that manages $7 billion in assets, has approved new guidelines that prohibit students from dressing up in stereotypical African-American attire on campus.

The policy, adopted in June by the Board of Trustees of the University of Pennsylvania, prohibits students who are enrolled in certain undergraduate and graduate programs from wearing the attire, the nonprofit said in a statement.

It goes on to state that wearing the clothing “in a manner that is offensive or offensive to a person of color” constitutes a violation.

The decision follows a complaint from a group of students that said wearing the apparel is an expression of racism and constitutes discrimination against students of color, the group’s lawyers said in an email.

The group was represented by the Center for Constitutional Rights, an advocacy group that has argued that the clothing is racially discriminatory.

In June, the university suspended its annual blackface celebration, saying it “has a long history of violating the First Amendment rights of students.”

The college’s decision follows similar rules put in place last year at the University to limit the costumes worn by students.
