PARC v. Commonwealth of Pennsylvania was a 1972 federal case, resolved by consent decree in the U.S. District Court for the Eastern District of Pennsylvania, that established the constitutional right of children with intellectual disabilities to a free public education. The decree struck down Pennsylvania statutes that let schools turn children away as “uneducable” and built the operational framework, free appropriate public education, least restrictive environment, procedural safeguards, and child find, that Congress adopted three years later in the law now known as the Individuals with Disabilities Education Act.
The Pennsylvania Laws the Case Attacked
Three provisions of Pennsylvania’s Public School Code worked together to keep children with intellectual disabilities out of school. One allowed districts to exclude any child who had not reached a “mental age of five years” by age eight. Another let schools deny admission to any child a school psychologist certified as “uneducable” or “untrainable.” A third exempted children with significant disabilities from the state’s compulsory attendance requirement entirely.
The combined effect was that exclusion was the default. Pennsylvania classified more than 100,000 children as having intellectual disabilities, and roughly half received no public education. Families who wanted schooling for their children had to find a private program, if one existed and they could afford it, or keep the child at home with no educational support.
The Constitutional Arguments
PARC brought the suit on behalf of 14 named children and grounded it in the Fourteenth Amendment.
The equal protection argument was direct. Pennsylvania offered free public education to every other child but categorically denied it to children with intellectual disabilities. That was a classification based on disability with no rational basis behind it.
The due process argument focused on how the exclusions happened. When a district labeled a child “uneducable,” the family got no hearing, no chance to present evidence, and no path to challenge the decision. The state was cutting off access to education with no procedural safeguards at all.
Expert testimony backed both arguments by establishing that all children with intellectual disabilities can benefit from education and training. That evidence proved decisive. The Commonwealth initially defended the statutes but chose not to contest the case at trial, and the parties negotiated a settlement instead.
What the Consent Decree Required
A three-judge panel approved the settlement as a consent decree on May 5, 1972. A consent decree carries the force of a court order and is enforceable through contempt if violated. The decree declared Pennsylvania’s exclusionary statutes unconstitutional and imposed a set of affirmative obligations on the state.1Justia Law. Pennsylvania Association for Retarded Children v. Commonwealth of Pennsylvania, 334 F. Supp. 1257
Free Appropriate Public Education
Pennsylvania had to provide “a free, public program of education and training appropriate to the child’s capacity” for every child with an intellectual disability between ages six and twenty-one.2Public Interest Law Center. PARC v. Commonwealth of Pennsylvania – Consent Decree “Appropriate” did real work in that phrase. A district could not comply by putting every child in the same room with the same lesson plan. Instruction had to fit the individual student, and families could not be charged.
Preference for Regular Classroom Placement
The decree set out a placement hierarchy that became known as the least restrictive environment principle. A regular public school class was preferable to a special class, a special class was preferable to a special school, and a special school was preferable to any setting outside the public school system. Children with disabilities were to be educated alongside non-disabled peers “to the maximum extent appropriate.” Removal from a regular classroom was permitted only when the nature of the disability meant education there could not work satisfactorily even with supplementary aids and services.2Public Interest Law Center.

Procedural Safeguards for Families
The decree filled the due process vacuum that had let schools exclude children without accountability. Parents were entitled to written notice before any change in their child’s placement. If they disagreed with a proposed change, they could request an impartial hearing.2Public Interest Law Center. PARC v. Commonwealth of Pennsylvania – Consent Decree The notice also had to inform parents of their right to an independent medical, psychological, and educational evaluation through their local mental health center, at no cost. The district’s own assessment was no longer the final word on the child.
Child Find
Pennsylvania was ordered to locate and identify every child with an intellectual disability who had previously been excluded. The state could not wait for families to come forward. Once identified, each child had to receive a comprehensive evaluation and an appropriate placement. The burden sat with the state.
How PARC Relates to Mills v. Board of Education
PARC was not the only 1972 disability education case, and its scope was narrower than the doctrine it inspired. PARC addressed children with intellectual disabilities specifically. Months later, the U.S. District Court for the District of Columbia decided Mills v. Board of Education, which involved children with a range of conditions including epilepsy and behavioral disabilities. Mills held that students with any type of disability were entitled to a public education and that a district could not justify exclusion by citing the cost of accommodations. The two cases worked in tandem: PARC supplied the structural mandates, and Mills confirmed those principles reached beyond one disability category.
How the Decree Became Federal Law
Before Congress acted, more than a million children with disabilities were excluded entirely from public schools, and many more received services so limited they amounted to exclusion in practice. Families often paid out of pocket for education outside the public system.3U.S. Department of Education. Section 1400 – Individuals with Disabilities Education Act
In 1975, Congress passed the Education for All Handicapped Children Act (Public Law 94-142), later renamed the Individuals with Disabilities Education Act. IDEA requires every state that accepts federal education funding to make a free appropriate public education available to all children with disabilities between ages three and twenty-one.4Office of the Law Revision Counsel. 20 USC 1412 – State Eligibility
IDEA’s least restrictive environment provision tracks the PARC decree closely. Children with disabilities must be educated with non-disabled children “to the maximum extent appropriate,” and removal from regular classrooms is permitted only when education there “cannot be achieved satisfactorily” even with supplementary aids and services.5U.S. Department of Education. Section 1412(a)(5) – Least Restrictive Environment The statute also codifies the procedural safeguards the decree pioneered, including prior written notice, the right to an impartial hearing, and access to independent evaluations, and applies them in every state.6U.S. Department of Education.
