This publication examines the requirement under the Individuals with Disabilities Education Act (IDEA) that mandates that all children with disabilities have available to them special education and related services designed to meet their unique needs and prepare them for employment and independent living. It investigates what is meant by "related services" and why they are an important part of educating children with disabilities. It begins by looking at the related services listed in the Federal regulations, eligibility, the evaluation process for assessing related services need, and the school's obligation to provide related services free of charge. Part 2 presents information about different types of related services, including artistic/cultural programs, assistive technology devices and services, audiology, counseling services, medical services, occupational therapy, orientation and mobility services, parent counseling and training, physical therapy, psychological services, recreation services, rehabilitation counseling services, school health services, social work services, speech-language pathology services, and transportation. Part 3 discusses how school districts provide children with disabilities with related services, how service are coordinated, and how services are funded. The last part reviews related services eligibility under Section 504 of the Rehabilitation Act of 1973. A list of relevant articles, books, and organizations is provided. (Contains 23 references.)
