The Individuals with Disabilities Education Act (IDEA) is a statute that authorizes grant programs that support special education services. Under the IDEA, a series of conditions are attached to the receipt of grant funds. These conditions aim to provide certain educational and procedural guarantees for students with disabilities and their families. The IDEA is primarily thought of as the nation's special education law, and Part B, which focuses on providing special education and related services to children with disabilities between the ages of 3 and 21 years old, is the largest part of the IDEA both in terms of populations served and funding level. However, the IDEA covers more than special education. The IDEA consists of four parts. Part A contains the general provisions, including the purposes of the act and definitions. The aforementioned largest part, Part B, contains provisions relating to the education of school aged children (the grants-to-states program) and the state grants program for preschool children with disabilities (Section 619). Part C, the focus of this report, authorizes state grants for programs serving infants and toddlers with disabilities. Finally, Part D contains the requirements for various national activities designed to improve the education of children with disabilities. Appendix A provides a more detailed summary of each of the four parts. Part C (Infants and Toddlers with Disabilities) of the Individuals with Disabilities Education Act (IDEA, P.L. 108-446) authorizes a formula grant program for infants and toddlers with disabilities (ages birth through two) and their families. A general purpose of these grants is to aid states in developing and implementing "a statewide, comprehensive, coordinated, multidisciplinary, interagency system that provides early intervention services for infants and toddlers with disabilities and their families."
