This information sheet summarizes findings from two reports: "Staffing Patterns and Team Models in Infancy Programs" by Jeanette McCollum and Mary-alayne Hughes, and "Early Intervention Team Approaches: The Transdisciplinary Model" by Geneva Woodruff and Mary McGonigel. The digest outlines the provisions of the Education of the Handicapped Amendments of 1986, (Public Law 99-457), the types of children who are eligible for services, and the services which must be made available. It describes the functioning of early intervention teams, which are composed of professionals representing a variety of disciplines: special education; social work; psychology; medicine; child development; and physical, occupational, and speech and language therapy; and which may also include parents. Three service delivery models that structure interaction among team members in different ways are discussed: multidisciplinary teams, interdisciplinary teams, and transdisciplinary teams. (JDD)
