This fact sheet describes provisions under Section 504 of the Rehabilitation Act of 1973 and Title II of the Americans with Disabilities Act of 1990 (ADA) that prohibit the discriminatory 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 of special education only when this placement is necessary to provide equal educational opportunity to them. Specific elements that must be considered to determine what the educational needs of a student with a disability may be are discussed and include: (1) the use of tests and evaluation materials to assess specific areas of the students' needs; (2) placement decisions made by a team that includes people who know about the students and understand the meaning of the evaluation information; (3) placement of the student with nondisabled students to the maximum extent appropriate to the needs of the student with a disability; (4) periodic reevaluations; (5) the development of an Individualized Education Program; (6) the establishment of procedural safeguards to allow parents or guardians to challenge decisions; and (7) the inclusion of students in extracurricular activities and nonacademic services.
