Which change in the treatment of children with disabilities resulted from congressional actions during the 20th century?

Congressional laws, especially the Education for All Handicapped Children Act of 1975 (later renamed the Individuals with Disabilities Education Act), expanded children’s right to a free public education. The law required schools to educate students with disabilities in the least restrictive environment, which often means learning in regular classrooms with appropriate support. Therefore, the change was that children with disabilities learn in regular classrooms.
