This is the 36th Annual Report to Congress on the Implementation of the "Individuals with Disabilities Education Act," 2014. Section 664(d) of the "Individuals with Disabilities Education Act" ("IDEA") (P.L. 108-446), as reauthorized in 2004, requires that the Department of Education report annually on the progress made toward the provision of a free appropriate public education to all children with disabilities and the provision of early intervention services to infants and toddlers with disabilities. The 36th Annual Report to Congress on the Implementation of the "Individuals with Disabilities Education Act," 2014" describes our nation's progress in: (1) providing a free appropriate public education (FAPE) for all children with disabilities and early intervention services to infants and toddlers with disabilities and their families; (2) ensuring that the rights of these children with disabilities and their parents are protected; (3) assisting states and localities in providing for the education of all children with disabilities; and (4) assessing the effectiveness of efforts to educate children with disabilities. The report focuses on the children and students with disabilities being served under "IDEA," Part C or B, nationally and at the state level. In particular, Part C of "IDEA" provides funds to states to assist them in developing and implementing statewide, comprehensive, coordinated, multidisciplinary interagency systems to make early intervention services available to all children from birth through age 2 with disabilities and their families, whereas Part B of "IDEA" provides funds to states to assist them in providing FAPE to children ages 3 through 21 with disabilities who are in need of special education and related services. Throughout this report, infants and toddlers served under "IDEA," Part C, children served under "IDEA," Part B, and students served under "IDEA" Part B, refer to individuals with disabilities who receive services under "IDEA," Part C or Part B. "Special education services," which is referenced throughout this report, is a term that is synonymous with services provided under "IDEA," Part B. Similarly, "early intervention services" is a term used synonymously with services provided under "IDEA," Part C. This report contains six major sections that address the five annual report requirements contained in section 664(d) of "IDEA." The sections are: (1) a summary and analysis of "IDEA" section 618 data at the national level; (2) a summary and analysis of "IDEA" section 618 data at the state level; (3) a summary and analysis of the U.S. Department of Education's (Department's) findings and determinations regarding the extent to which states are meeting the requirements of "IDEA," Parts B and C; (4) a summary of special education research conducted under Part E of the "Education Sciences Reform Act of 2002"; (5) a summary of national special education studies and evaluations conducted under sections 664(a) and (c) of "IDEA"; and (6) a summary of the extent and progress of the assessment of national activities, which focus on determining the effectiveness of "IDEA" and improving its implementation. The content of this report differs from that of the "35th Annual Report to Congress, 2013" in the following ways: (1) it presents some data concerning "IDEA," Part B "maintenance of effort (MOE) reduction" and coordinated early intervening services (CEIS); and (2) data for the three freely associated states (the Federated States of Micronesia, the Republic of Palau, and the Republic of the Marshall Islands) are considered along with those for the 50 states, the District of Columbia, Bureau of Indian Education (BIE) schools, the Commonwealth of Puerto Rico, and the four outlying areas (American Samoa, Guam, the Northern Mariana Islands, and the Virgin Islands) when the entirety of the United States is being represented. The following are appended: (1) Infants, Toddlers, Children, and Students Served Under "IDEA," by Age Group and State; (2) "Developmental Delay" Data for Children Ages 3 Through 5 and Students Ages 6 Through 9 Served Under "IDEA," Part B; (3) Differences in State Reporting of "IDEA," Part B, Disabilities; and (4) "IDEA" Part B Maintenance of Effort Reduction and Coordinated Early Intervening Services.
