What court case extended a previous decision to include all children with disabilities?

The court case that extended a previous decision to include all children with disabilities is Board of Education v. Rowley (1982). This landmark decision clarified the requirement of providing a "free appropriate public education" (FAPE) under the Individuals with Disabilities Education Act (IDEA) for all children with disabilities, emphasizing that educational benefits must be meaningful and tailored to the individual needs of each student. This case built upon earlier rulings, reinforcing the rights of children with disabilities to receive appropriate educational services in public schools.
