On December 3, 2004, President Bush signed the Individuals with Disabilities Education Improvement Act (IDEIA 2004) into law. This law reauthorized and amended the Individuals with Disabilities Education Act (IDEA). On August 3, 2006, the U.S. Department of Education issued the regulations implementing the IDEIA 2004. The changes in the IDEIA 2004 and the 2006 regulations are both sweeping and important. These changes, added to the mandates of the IDEA, require that special education teachers and administrators know and understand their duties and obligations under the law. Individuals are cautioned that the Departments of Education in their respective states will still need to change their regulations to align with the IDEA. It is, therefore, important that they watch events in their own states. In this review, the authors discuss 20 specific ways that teachers and administrators may ensure compliance with the mandates of the IDEIA 2004. (Contains 1 table.)
