Nondiscrimination on the Basis of Disability
Also known as: Disability Nondiscrimination, Prohibition of Disability Discrimination
Simply put
Nondiscrimination on the basis of disability is the legal principle that people with disabilities must not be treated unfairly or excluded because of their disability. Under US laws such as the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act, qualified individuals with disabilities are protected from discrimination in many areas of life. This includes prohibiting outright denials of equal treatment as well as rules or criteria that would improperly bar or separate people with disabilities.
Formal definition
Nondiscrimination on the basis of disability refers to statutory and regulatory prohibitions against discrimination toward qualified individuals with disabilities. Under the ADA, these protections extend across multiple contexts, while Section 504 of the Rehabilitation Act prohibits disability-based discrimination in programs or activities receiving federal financial assistance. Implementing regulations generally prohibit overt denials of equal treatment as well as the establishment of exclusive or segregative eligibility criteria that would bar or separate individuals with disabilities. A 'qualified individual with a disability' is commonly defined by reference to a person who has a physical or mental impairment (and related statutory criteria), as set out in the applicable statutes and regulations. The specific scope, covered entities, and obligations vary by authority, for example, the different titles of the ADA and Section 504, so the applicable framework should be identified for any given situation.

Why it matters
Nondiscrimination on the basis of disability is one of the foundational principles of US disability rights law. It establishes that people with disabilities cannot be lawfully excluded from or treated unequally in many areas of life simply because of their disability. For organizations, understanding this principle is essential because it underlies a range of specific obligations, from prohibiting outright denials of equal treatment to prohibiting eligibility rules or criteria that would improperly bar or segregate individuals with disabilities. These protections appear in different forms across authorities such as the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act.
Who it's relevant to
Compliance officers
Compliance officers need to identify which authority applies to their organization, whether an ADA title, Section 504, or another framework, because the covered entities and obligations differ. Determining the correct framework is a necessary first step before assessing specific nondiscrimination duties.
Legal counsel
Attorneys advising covered organizations must interpret how the general prohibition on disability discrimination applies to particular facts, including how covered eligibility criteria are evaluated and how "qualified individual with a disability" is defined under the applicable statute and regulations. Because requirements evolve through regulation and case law, counsel should consult current agency rulemaking for authoritative application.
State and local government entities
Programs and activities operated by state and local government are subject to disability nondiscrimination requirements, and separately, entities receiving federal financial assistance are subject to Section 504's prohibition on disability-based discrimination. Public-sector organizations should determine which of these authorities apply to their specific programs.
Recipients of federal financial assistance
Organizations that receive federal financial assistance are subject to Section 504, which prohibits discrimination on the basis of disability in programs or activities receiving such assistance. These entities should evaluate their programs against Section 504's requirements as interpreted by the relevant agency.
Business leaders and program administrators
Leaders responsible for services, programs, or activities should understand that nondiscrimination duties may prohibit not only overt denials of equal treatment but also facially neutral criteria that would improperly exclude or segregate people with disabilities.

Inside Nondiscrimination on the Basis of Disability
Statutory Basis
Nondiscrimination on the basis of disability is a core principle of US civil rights law, expressed through statutes such as the Americans with Disabilities Act (ADA) and the Rehabilitation Act of 1973. These laws prohibit covered entities from excluding, denying benefits to, or otherwise discriminating against individuals with disabilities.
Covered Entities and Applicable Authorities
Different provisions apply to different actors. Title II of the ADA applies to state and local government entities, while Title III applies to places of public accommodation. Section 504 of the Rehabilitation Act applies to programs and activities receiving federal financial assistance, and Section 508 addresses information and communication technology in covered federal contexts. The applicable authority depends on who the covered entity is.
Equal Access and Effective Communication
The principle generally requires that individuals with disabilities have access to goods, services, programs, and information comparable to that afforded others. In the digital context, this is often discussed in terms of effective communication and equal access to online content and functionality.
Reasonable Modifications and Accommodations
Nondiscrimination commonly includes an obligation to make reasonable modifications to policies, practices, and procedures, and to provide auxiliary aids and services, unless doing so would fundamentally alter the service or impose an undue burden, as those limits are defined under the applicable law.
Relationship to Technical Standards
The ADA is a civil rights law and does not itself contain detailed web technical specifications. Courts, settlements, and agency guidance have often referenced the Web Content Accessibility Guidelines (WCAG), published by the W3C's Web Accessibility Initiative, as a benchmark, with Level AA most commonly cited as a target. WCAG conformance is a technical measure distinct from the legal obligation not to discriminate.
Common questions
Answers to the questions practitioners most commonly ask about Nondiscrimination on the Basis of Disability.
Does the ADA itself specify that my website must meet a particular version of WCAG?
Not directly. The Americans with Disabilities Act is a US civil rights law that prohibits discrimination on the basis of disability; it does not itself contain detailed web technical specifications. WCAG, by contrast, is a set of technical guidelines published by the W3C through the Web Accessibility Initiative. Courts, settlements, and some agency guidance have frequently referenced WCAG (commonly Level AA) as a benchmark for measuring accessibility, but that is generally different from the statute codifying a specific version. Where a specific WCAG version applies to your situation, it typically arises from a particular regulation, settlement agreement, or agency guidance, and you should attribute the requirement to that source. Consult qualified legal counsel for your circumstances.
If I pass automated accessibility checks or meet WCAG success criteria, does that mean I am compliant and protected from legal claims?
No. Meeting WCAG success criteria and passing automated checks does not guarantee an accessible experience for all users, nor does it guarantee immunity from legal claims. Automated testing detects only a portion of accessibility issues; manual testing and testing with assistive technologies are generally required to evaluate real-world usability. Conformance, usability, and legal compliance are distinct concepts. Nondiscrimination obligations may be assessed against facts, case law, and evolving regulation rather than a single test result. This is general information and not legal advice; consult qualified legal counsel.
Which authority applies to my organization when addressing nondiscrimination on the basis of disability?
It depends on who you are. Title II of the ADA generally applies to state and local government entities, while Title III of the ADA generally applies to places of public accommodation. Section 508 applies to federal agencies and certain covered federal contexts, and Section 504 of the Rehabilitation Act addresses programs and activities receiving federal financial assistance, among other covered contexts. These frameworks have distinct scopes and should not be treated as interchangeable. Identify which authority or authorities cover your organization, and consult qualified legal counsel to confirm your obligations.
What testing approach helps demonstrate a good-faith effort toward nondiscrimination?
A layered approach is commonly recommended. Automated tools can efficiently surface certain categories of issues, but because they detect only a portion of potential problems, manual review and testing with assistive technologies (such as screen readers and keyboard-only navigation) are generally needed to evaluate the actual user experience. Involving people with disabilities in testing can further help identify barriers that tools miss. Documenting your process, findings, and remediation efforts may support a demonstration of ongoing good-faith work, though it does not by itself guarantee legal compliance.
Which WCAG conformance level should we target for our accessibility work?
Level AA is the level most commonly cited as a target in settlements, guidance, and organizational policies, though the applicable expectation for your situation may depend on any specific regulation, agreement, or agency guidance that covers you. When setting a target, be precise about the WCAG version as well (for example 2.0, 2.1, or 2.2), because some success criteria were added in later versions. Confirm the specific version and level appropriate to your obligations with qualified legal counsel and against current agency rulemaking.
How should we handle the fact that accessibility requirements can change over time?
Treat accessibility as an ongoing program rather than a one-time project. Requirements evolve through regulation, agency rulemaking, and case law, and WCAG itself is periodically updated across versions. Practical steps commonly include maintaining an accessibility policy, scheduling recurring testing and remediation, monitoring updates to relevant standards and guidance, and periodically reviewing your obligations with qualified legal counsel. Because this guidance is general and not legal advice, verify current requirements against the authorities that apply to your organization.
Common misconceptions
The ADA mandates a specific version of WCAG for all websites.
The ADA is a civil rights statute and does not itself codify detailed web technical specifications. WCAG is often cited as a benchmark in settlements, regulations, or agency guidance rather than being a universal statutory requirement. Any specific version or conformance level requirement should be attributed to the particular settlement, regulation, or guidance that established it, and requirements continue to evolve through rulemaking and case law.
All US accessibility laws apply to the same entities in the same way.
Section 508, Section 504, and the ADA are distinct in scope. Section 508 applies to covered federal contexts, Section 504 to recipients of federal financial assistance, ADA Title II to state and local government, and ADA Title III to places of public accommodation. Which authority applies depends on the type of entity involved.
Meeting WCAG or passing automated checks guarantees legal compliance and an accessible experience.
Conformance, usability, and legal compliance are separate. Meeting success criteria or passing automated tools does not guarantee an accessible experience for all users or immunity from legal claims. Automated testing detects only a portion of issues, so manual testing and testing with assistive technology are generally needed.
Best practices
Identify which legal authority applies to your organization (for example ADA Title II, ADA Title III, Section 504, or Section 508) before determining obligations, since scope and requirements differ by entity type.
Treat WCAG conformance, commonly targeting Level AA, as a technical benchmark that supports nondiscrimination goals, while recognizing it is distinct from the legal obligation itself.
Combine automated testing with manual review and assistive technology testing, since automated tools detect only a portion of accessibility issues.
Establish processes for reasonable modifications, auxiliary aids, and effective communication so individuals with disabilities can access services comparably to others.
Monitor evolving regulations, agency guidance, and case law, since requirements in this area continue to develop over time.
Consult qualified legal counsel for questions about compliance, as glossary guidance is educational and not legal advice.
