Colleges and universities are not always the safe havens they are thought to be; college women are at higher risk for sexual assault than their non-college-bound peers. Yet, many rapes and attempted rapes are unreported, perhaps because for the majority of these crimes, victim and assailant are acquainted. Schools vary widely in how they comply with Federal requirements to report and respond to sexual victimization. These are among the findings from the first major survey of the Nation's colleges and universities to inquire about sexual assault on campus and how schools are reporting and handling the problem. Many schools need guidance on how to comply with Federal requirements to disclose security procedures, report crime data, and ensure victims' rights. Promising practices in prevention, policy, victim support services, and other areas are discussed.
