The District shall provide a free appropriate public education in the least restrictive environment and necessary related services to all children with disabilities enrolled in the District, as required by the Individuals With Disabilities Education Act (IDEA) and implementing provisions of the School Code, Section 504 of the Rehabilitation ACT of 1973, and the Americans with Disabilities Act. The term "children with disabilities,' as used in this policy, means children between ages 3 and 21 (inclusive) for whom it is determined, through definitions and procedures described in the Illinois State Board of Education's Special Education rules, that special education services are needed. It is the intent of the District to ensure that students who are disabled within the definition of Section 504 of the Rehabilitation Act of 1973 are identified, evaluated, and provided with appropriate educational services. Students may be disabled within the meaning of Section 504 of the Rehabilitation Act even though they do not require services pursuant to the IDEA. For students eligible for services under IDEA, the District shall follow procedures for identification, evaluation, placement, and delivery of services to children with disabilities provided in the Illinois State Board of Education's Special Education rules. For those students who are not eligible for services under IDEA, but, because of disability as defined by Section 504 of the Rehabilitation Act of 1973, need or are believed to need special instruction or related services, the District shall establish and implement a system of procedural safeguards. The safeguards shall cover students' identification, evaluation, and educational placement. This system shall include notice, an opportunity for the students' parent(s) guardian(s) to examine relevant records, an impartial hearing with opportunity for participation by the students' parent(s) guardian(s), and representation by counsel, and a review procedure. The District may maintain membership in one or more cooperative associations of school districts that shall assist the School District in fulfilling its obligations to the District's disabled students.
