Are Common Core and Title IX linked?

Hans Bader writes a letter to the editor in the Washington Post on Common Core: 

"George F. Will was right to lament that “the Education Department’s Office for Civil Rights has stripped colleges and universities of a crucial component of self-government” by micromanaging college disciplinary systems, using Title IX as a “pretext.”

The standard of proof in student disciplinary cases generally used to be “clear and convincing evidence.” But in April 2011, the Office for Civil Rights, where I used to work, rejected that consensus. It wrongly ordered colleges to lower the standard of proof to a mere “preponderance” for sexual harassment or abuse allegations. In rejecting the higher standard, it overturned long-standing rules at Harvard Law School, Princeton University and many colleges. That higher standard was voluntarily adopted and was accepted by judges."
