Final answer:
PARC v. Commonwealth of Pennsylvania (1972) granted educational rights to students with disabilities, leading to the Education for All Handicapped Children Act and the later IDEA, which guaranteed individualized education plans for these students.
Step-by-step explanation:
PARC v. Commonwealth of Pennsylvania (1972) granted a free appropriate public education to c) Students with disabilities. This decision ensured that children with special needs, including intellectual disabilities and mental illness, were entitled to free education in the public school system, despite any additional costs their education might entail. The case established that the financial considerations of a school district could not outweigh the rights of children with disabilities to receive an appropriate education.
Following this case, the Education for All Handicapped Children Act was passed, which later became known as the Individuals with Disabilities Education Act (IDEA). This act emphasized the inclusion of children with disabilities in regular educational settings and guaranteed that they would have individualized education plans suited to their unique learning needs.
