The Individuals with Disabilities Improvement Act (IDEA 2004), reauthorizes and modifies IDEA. Changes, which take effect on July 1, 2005, include modifications in the IEP process and procedural safeguards, increased authority for school personnel in special education placement decisions, and alignment of IDEA with the No Child Left Behind Act. The 2004 reauthorization also requires school districts to use the Response to Intervention (RTI) approach as a means for the early identification of students at risk for specific learning disabilities. RTI provides a three-tiered model for screening, monitoring, and providing increasing degrees of intervention using “research-based instruction" with the overall goal of reducing the need for special education services.
