In the early 1970s, children with cognitive impairments faced significant barriers to accessing public education. State laws allowed schools to deny education to children who had not reached a mental age of five by the time they were eight years old. U.S. schools educated only one in five children with disabilities. This exclusionary practice left many children without the opportunity to learn and develop in a supportive educational environment.
"I was ridiculed, I was teased. But I learned how to deal with that from a very early age and I did deal with it. I didnβt allow myself to be bullied, but not in a confrontational wayβ¦ if children laughed at me, I laughed at them. If they said to me, βOh, you walk funny β you walk like this.β Iβd go, βNo, no, youβre doing it wrong. This is how I walk.β And Iβd put it on even more."

Some children were placed in special institutions or asylums, which were often overcrowded and provided minimal educational opportunities. These institutions focused more on custodial care rather than education.

The legal framework did not support the inclusion of children with disabilities in public education. Without federal legislation, states and districts had no obligation to provide services. Social stigmas and beliefs that these children couldn't benefit from education furthered their exclusion. Families faced high costs for private education, leaving most children homebound without formal instruction.

"Kevin was denied access to the local primary school where his brothers and sisters had gone and instead went to Greenbank School of Rest and Recovery from the age of four to seven. It was just a place to contain disabled people, and maybe give the parents a bit of a respite. But the education was⦠way down the bottom of the list of priorities. He was educated with kids from age four and a half to sixteen with all different disabilities and impairments in the same room."

From 1903 to 1950, Pennhurst State School and Hospital reflected societyβs practice of institutionalizing children with disabilities rather than providing educational opportunities. Its conditions and treatment of residents later led to the formation of advocacy groups.

"Massive custodial institutions were built to warehouse the retarded for life. The aim was to halt reproduction of the retarded and nearly extinguish their race."βββββββ
