The increasing prevalence of homelessness among young children and families in the United States is described, as is the developmental impact on young children and cost to society. Although services are mandated for this population under the McKinney­-Vento Act, Education of Homeless Children and Youth Program, and the Individuals With Disabilities Education Improvement Act of 2004, barriers continue to exist for young children related to identification and access to quality early intervention services and supports. These barriers, as well as a collaborative approach to the identification and delivery of early intervention services, are discussed. In addition, recommendations for future practice and research are provided.
