Reauthorization of the IDEA 2004

Links to important references and resources on the Reauthorization of the Individuals with Disabilities Education Act (IDEA).

The Individuals with Disabilities Education Act (IDEA) is the primary federal program that authorizes state and local aid for special education and related services for children with disabilities. On December 3, 2004, President Bush signed the Individuals with Disabilities Education Improvement Act, a major reauthorization and revision of IDEA. The new law preserves the basic structure and civil rights guarantees of IDEA but also makes significant changes in the law. Most provisions of Public Law (PL) 108-446 go into effect on July 1, 2005. The requirements regarding “highly qualified” special education teachers became effective immediately upon signature.

California Statute Changes, October 7, 2006

Legislation was introduced during the 2007 state legislative session to align California Education Code (EC) to the final IDEA regulations.

  • State Assembly Bill 1662 (Lieber and Daucher) made changes to California special education statutes to bring them into harmony with federal changes enacted through the 2004 reauthorization IDEA. The bill was signed by the Governor on October 7, 2005.

  • Assembly Bill 1841 (Buchanan) aligns EC 56346 with the amended IDEA Part B regulations at 34 Code of Federal Regulations (CFR) 300.300(b)(4). This regulation requires that parental revocation of consent for the continued provision of special education and related services must be in writing, and that upon revocation of consent, a public agency must provide the parent with prior written notice, in accordance with 34 CFR Section 300.503. A letter, alerting all local educational agencies addressing this issue, was mailed January 6, 2009.
