FRANKLIN, Mass. (MyFoxBoston.com) — A dispute over graduation gowns has begun at Franklin High School.

At issue is whether all students should wear the same color robes so others aren’t discriminated against.

At the high school’s graduation ceremony, it has been a long running tradition for boys to wear blue gowns and for girls to wear white. But that tradition is changing

“There will be a change, I think,” said Peter Light, the school’s principal. “We have yet to determine what that change looks like.”

The call for change started when members of the school’s Gay Student Alliance organization became concerned with transgender students and gender equality.
