Research has shown that both young children with disabilities and their peers benefit from participating together in quality programs and community activities. However, inclusive opportunities for young children with disabilities are not systematic, comprehensive or necessarily of high quality. Four federal agency partners recognized the need to promote collaborative efforts in states that would result in high quality inclusive opportunities for all children and families. They created the Expanding Opportunities Initiative and supported it through the coordinated efforts of their technical assistance (TA) resources. This interagency inclusion initiative began in 2005 and has continued to be supported by the federal partners each year.
