If your child has autism spectrum disorder (ASD), you have probably heard the phrase “ADA accommodations” come up in conversations with schools, doctors’ offices, or community programs. But what exactly is the Americans with Disabilities Act (ADA), where did it come from, and what does it mean for your family?

At Maxim Healthcare’s behavioral division (“Maxim Behavioral”), we believe that informed families are empowered families. This blog breaks down the history of the ADA in plain language, focusing on what matters most to caregivers and parents.

Before the ADA: a world without protections

To understand why the ADA was such a turning point, you need to know what daily life looked like for people with disabilities before it existed. As the Embryo Project Encyclopedia describes, most public spaces were not accessible for wheelchair users, children with intellectual disabilities were frequently excluded from public schools or institutionalized, and employers could legally refuse to hire someone simply because of their disability status. Some cities even had “ugly laws” that gave police the right to fine or jail people with visible disabilities for appearing in public.

The push for change grew out of decades of advocacy by people with disabilities and their allies, drawing inspiration from the civil rights and women’s rights movements. Early milestones included the Rehabilitation Act of 1973, which protected people with disabilities in federally funded programs, and the Education for All Handicapped Children Act of 1975, later renamed the Individuals with Disabilities Education Act (IDEA), which established the right of children with disabilities to a free public education. According to the Embryo Project Encyclopedia, before that law, only about 20 percent of students with disabilities were receiving any public education at all. These were important gains, but they covered only narrow areas of public life. Advocates kept pushing for something broader.

How the ADA became law

The first version of the ADA was introduced in Congress in 1988. Over the following two years, advocates and lawmakers built support through public hearings that collected firsthand testimony about the barriers people with disabilities faced every day. The bill ultimately passed the Senate by a vote of 76 to 8, with backing from both parties. According to the ADA National Network, key champions included Senator Bob Dole, who had been seriously injured during World War II, Senators Ted Kennedy and Tom Harkin, and Representative Tony Coelho, who had epilepsy.

On July 26, 1990, President George H.W. Bush signed the ADA into law. As he did, he said, “Let the shameful wall of exclusion finally come tumbling down.” It was a defining moment for disability rights in the United States.

What the ADA covers

As detailed on ADA.gov, the ADA is organized into five titles, each covering a different area of public life. Title I prohibits employment discrimination and requires employers with 15 or more employees to provide reasonable accommodations for workers with disabilities. Title II requires that state and local government programs and services, including public schools, be accessible. This is the title most directly relevant to your child’s school experience. Title III requires businesses and places open to the public, such as restaurants, stores, hospitals, and libraries, to be physically accessible. Title IV ensures that phone and television services are accessible to people who are deaf or hard of hearing. Title V includes anti-retaliation protections for anyone who exercises or supports the exercise of ADA rights.

Together, these titles transformed the physical and legal landscape of American life. Wheelchair ramps, accessible restrooms, closed captioning, and employment protections that families now rely on every day all trace back to the ADA.

When the law was narrowed, and how Congress responded

In the years following the ADA’s passage, a series of Supreme Court decisions interpreted the law in ways that significantly limited who it protected. In Sutton v. United Airlines (1999), the Court ruled that disability must be assessed after accounting for any mitigating measures, such as medication or assistive devices. This meant that someone whose condition was well-managed might be considered “not disabled enough” for the ADA to apply, even if they faced discrimination because of it. A 2002 ruling set an equally high bar for what counted as a substantially limiting impairment. As documented by the U.S. Department of Justice, these decisions led to the exclusion from ADA coverage of people with cancer, diabetes, epilepsy, ADHD, learning disabilities, and other conditions.

Congress responded by passing the ADA Amendments Act (ADAAA) in 2008, which was signed into law by President George W. Bush and became effective on January 1, 2009. According to the Job Accommodation Network, the ADAAA overturned more than a decade of restrictive court rulings affecting people with autism, ADHD, developmental delays, and intellectual disabilities. The two most important changes for families: first, a child’s disability is now assessed based on the condition itself, not on how well it is managed with supports, medication, or therapy. Second, the definition of “major life activities” was expanded to include neurological and brain functions, meaning that challenges with communicating, concentrating, thinking, learning, and interacting with others are now explicitly recognized as areas where disability protections apply. According to guidance from the U.S. Department of Education, a student with ASD is now clearly covered under the ADA and Section 504 of the Rehabilitation Act.

What the ADA means for your family today

The ADA is not a historical artifact. It is a living law that shapes your child’s daily life in concrete ways. In schools, it works alongside IDEA and Section 504 to ensure students with disabilities are not excluded from programs or activities and receive appropriate accommodations. In community settings, it requires that healthcare providers, recreation centers, libraries, and government offices be accessible and make reasonable modifications when needed. In employment, as your child grows into adulthood, the ADA’s protections ensure that, as outlined by the U.S. Equal Employment Opportunity Commission, employers must consider reasonable accommodations before concluding that a person with a disability cannot do a job.

The ADA celebrated its 35th anniversary in 2025. As the ADA National Network notes, the work continues, with ongoing updates to regulations, new guidance on digital accessibility and sustained advocacy from the disability community. The history of the ADA is ultimately a story about what happens when people refuse to accept that exclusion is inevitable. That same spirit lives in every family that pushes for the right accommodations and refuses to accept less than what their child deserves.
