These guidance documents were issued by the U.S. Department of Education Office for Civil Rights. This 2001 Sexual Harassment Guidance reaffirms the compliance standards that OCR applies in investigations and administrative enforcement of Title IX of the Education Amendments of 1972 regarding sexual harassment. The guidance provides the principles that a school should use to recognize and effectively respond to sexual harassment of students in its program as a condition of receiving Federal financial assistance. This 2011 Dear Colleague Letter on Sexual Violence explains that the requirements of Title IX of the Education Amendments of 1972 cover sexual violence and reminds schools of their responsibilities to take immediate and effective steps to respond to sexual violence in accordance with the requirements of Title IX. This 2013 Dear Colleague Letter on Retaliation reminds school districts, postsecondary institutions, and other recipients that retaliation is also a violation of Federal law. The letter seeks to clarify the basic principles of retaliation law and to describe OCR's methods of enforcement.
