WASHINGTON — Reacting to a series of highly publicized rapes on college campuses, the White House on Monday released guidelines that increase the pressure on universities to more aggressively combat sexual assaults on campus.

The recommendations urge colleges, among other measures, to conduct anonymous surveys about sexual assault cases, adopt anti-assault policies that have been considered successful at other universities and to better ensure that the reports of such crimes remain confidential. The guidelines are contained in a report by a White House task force that President Obama formed early this year, and the administration is likely to ask Congress to pass measures that would enforce the recommendations and levy penalties for failing to do so. The government will also open a website, NotAlone.gov, to track enforcement and provide victims with information.

Many advocates for such a crackdown may see the proposals as an inadequate response to a crisis, but the White House is hamstrung about what it can do without congressional action and has just begun its own attack on the issue.

“Colleges and universities need to face the facts about sexual assault,” Vice President Joseph R. Biden Jr. said. “No more turning a blind eye or pretending it doesn’t exist. We need to give victims the support they need, like a confidential place to go, and we need to bring the perpetrators to justice.”
