A law that says that no qualified person shall, on the basis of a disability, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any program or activity that receives or benefits from federal financial assistance. The Office for Civil Rights of the Department of Education (OCR) enforces this law for all elementary, secondary, and postsecondary schools. The OCR prohibits specific discriminatory activities, such as the assignment of students with disabilities to segregated classes or facilities. (In elementary and secondary schools, students with disabilities may be assigned to separate facilities or courses only when such placement is necessary to provide them equal educational opportunity and when the separate facilities and services are comparable to other facilities and services.)
