This initial issue of "Early Edition" launches the first edition of Tennessee's newsletter dedicated to the implementation of programs and services for young children with disabilities under the Individuals with Disabilities Education Act (IDEA). The period of early childhood is the foundation for all future learning and achievement for children. Tennessee's Department of Education and its Division of Special Education have the responsibility for leading the State's efforts to ensure resources and supports are available to the youngest citizens and their families to promote each child's developmental and educational success. As the lead agency for the State's system of services to infants and toddlers and preschool children, the Department is dedicated to unified and continuous service delivery under IDEA. This newsletter establishes a venue for sharing new and exciting information from the perspective of families and the multiplicity of stakeholders that comprise the structure of the State's service system. The format is designed so that the organization of information in each edition is related to key components of IDEA. Part A of IDEA includes the general provisions of the act. Newsletter articles related to this part will provide information such as updates on changes in regulations, policy, monitoring, state/program improvement, and other issues related to governance of IDEA implementation. Part B of IDEA lays out the rights and processes for the provision of FAPE to school-aged children and includes elements specifically related to preschool services. In this area of the newsletter, information on promising and science-based practices in the delivery of preschool services will be presented. Preschool programs that have demonstrated success in key areas of service delivery will be featured. Part C of IDEA outlines services to infants and toddlers with disabilities and their families. It requires the coordination of services and supports to families to enhance their capacity to promote their child's development. A key purpose of Part C is to reduce the likelihood of the need for extensive interventions over the lifespan of the child. The model of interagency coordination established under Part C exemplifies the cooperation and teamwork that is the essence of IDEA. This section of the newsletter provides information on promising and science-based practices in the delivery of early intervention services and features various service providers across the State. Part D of IDEA deals with personnel development, research activities, and dissemination of information. Articles in this area of the newsletter will provide current information related to research-based practices, training, and technical assistance activities and resources. This issue of "Early Edition" contains four articles corresponding to each IDEA part. These are: (1) The Interagency Coordinating Council Promotes Hands-on Involvement (Lynne F. Harmon); (2) The Next Steps for Preschoolers (Debbie Cate, Sondra Dade, and Kay Flowers); (3) Tomorrow's Success Begins Today (Susan Addison); and (4) Information is on the Way (Alexis Burkett). [This newsletter is published quarterly by Tennessee's Early Intervention System in collaboration with the Office of Early Childhood Programs, Division of Special Education within the Tennessee State Department of Education and the newsletter Advisory Committee.]
