The No Child Left Behind Act (NCLB) and the Individuals with Disabilities Education Act (IDEA) are two of the nation's most important federal laws relating to the education of children. While NCLB seeks to improve the education of all children--with an emphasis on children from low-income families--IDEA focuses on the individual child and seeks to ensure specialized services for children with disabilities so that they may benefit from education. Lately, these two laws have taken on new importance to parents of students with disabilities. NCLB provisions apply to all students, including those whose disabilities require special education. So it is important that parents understand the requirements of NCLB. IDEA, in its latest update by Congress, has been more closely aligned with NCLB, making it equally important that parents become familiar with the ways the two laws have been positioned to work together to improve academic achievement of students with disabilities. This brief guide provides information for parents about the meaning of NCLB; the meaning of IDEA; how NCLB and IDEA work together; academic content and achievement standards; annual assessments; school accountability; and highly qualified teachers. Sections providing answers to frequently asked questions; a glossary; and a list of additional resources conclude the guide.
