Under the No Child Left Behind Act (NCLB), public school students throughout the country must participate in annual testing in specific academic areas and grades outlined in the law, including students with disabilities. Requiring the inclusion of all students with disabilities in state- and district-wide assessments helps ensure that schools, school districts and states are held accountable for the achievement of these students. According to NCLB, students with disabilities (those covered under the Individuals with Disabilities Education Act or Section 504 of the Rehabilitation Act) must be provided the appropriate accommodation necessary to participate in these tests. Making determinations about the appropriate accommodations that students with disabilities need in order to fully and equally participate in large scale testing is a critical component of developing a student's Individualized Education Program (IEP) or Section 504 Plan. IEP/504 team members, including parents, must engage in a thoughtful process that determines the necessary accommodations to facilitate the student's access to grade level instruction and full participation in state/district assessments. The selection of appropriate accommodations is the focus of this parent advocacy brief.
