The concept of integrating children with disabilities into public school classrooms has paralleled the movement to integrate children of different races. In 1975, Congress enacted the Education for All Handicapped Children Act of 1975 (EAHCA), which became effective in 1977. Through regulations detailing precise procedural guidelines, EAHCA has attempted to define the major components of a free appropriate public education (FAPE) for children with disabilities. In 1990, Congress reauthorized the EAHCA and changed its title to the Individuals with Disabilities Education Act of 1990 (IDEA). This guidebook describes court litigation defining the application of the act with respect to the following areas: eligibility, assessment, individualized education program (IEP), appropriateness, least restrictive environment, related services, residential placements, changes in placement, expulsion, private schools, due process procedures, and remedies for violations. Appendices contain subchapters I and II of IDEA, selected federal regulations, and a U.S. Department of Education memorandum on discipline of children with disabilities. (LMI)
