Discrimination against students on the basis of sex is prohibited in education programs or activities that receive Federal financial assistance. The Office for Civil Rights of the Department of Education enforces the law prohibiting specific discriminatory activities. The law applies to elementary and secondary as well as postsecondary schools. With certain exceptions, elementary and secondary schools may not assign students to separate classrooms or activities, or prevent them from enrolling in courses of their choice, on the basis of sex. This includes health, physical education, industrial arts, business, vocation, technical, home economics, music, and adult education courses. This brochure outlines the conditions under which educational institutions controlled by religious organizations may request an exception, and regulations pertaining to counseling and appraisal materials, student marital or parental status, and student assignment in athletics. A list of regional Civil Rights Offices is included. (LMI)
