Federal early childhood special education policy: a model for the improvement of services for children with disabilities.

Services in early childhood special education for children with disabilities, birth through 5 years, and their families have expanded and improved substantially in the past 25 years. The federal government, through legislation, regulation, and a variety of incentives, has played an integral role in this progress. The authors review the evolution of federal education policy in early childhood and the accomplishments achieved, including the development of the Handicapped Children's Early Education Program, the Early Childhood Research Institutes, and Public Law 99-457, the Handicapped Infant and Toddler Program (Part H). This history can serve as a model for federal involvement in the improvement of services for other groups of individuals with special needs.
