Section 508 of the Rehabilitation Act

Also known as: Section 508, Section 508, Section 508 compliance, 29 U.S.C. § 794d
Simply put

Section 508 is a US federal law that requires federal agencies to make their electronic and information technology accessible to people with disabilities. Under it, agencies must give employees and members of the public with disabilities access to information that is comparable to the access available to others. It applies to the federal sector rather than to private businesses or state and local governments.

Formal definition

Section 508 of the Rehabilitation Act, codified at 29 U.S.C. § 794d, is a federal statute requiring covered federal agencies to ensure that information and communication technology (ICT) they develop, procure, maintain, or use is accessible to individuals with disabilities, providing access comparable to that available to people without disabilities. Its scope is the federal sector and is distinct from Title II and Title III of the ADA, which apply to state and local government and to places of public accommodation, respectively. Detailed technical requirements are established through the U.S. Access Board's ICT accessibility standards and related federal guidance; this entry is general information and not legal advice, and applicability and current requirements should be verified against controlling regulations and agency guidance.

Why it matters

Section 508 establishes a baseline expectation that the federal government's own technology works for people with disabilities. Because federal agencies develop, procure, maintain, and use a vast range of information and communication technology (ICT), the law affects how millions of people interact with government, whether they are federal employees using internal systems or members of the public accessing services and information online. Under Section 508, agencies must provide access that is comparable to the access available to people without disabilities, which shapes decisions about websites, documents, software, and the products agencies buy from vendors.

The law also carries significant influence beyond the federal sector itself. Because vendors that want to sell ICT to the federal government must be able to demonstrate that their products meet applicable accessibility requirements, Section 508 effectively encourages accessibility in the broader technology marketplace. This procurement leverage is one of the reasons the statute is frequently discussed in accessibility circles even by organizations that are not directly covered by it.

It is important to keep Section 508's scope in perspective. It applies to the federal sector and is distinct from Title II of the ADA, which applies to state and local government, and Title III, which applies to places of public accommodation. Private businesses and non-federal entities are generally not directly governed by Section 508, though they may encounter its requirements when contracting with federal agencies. This entry is general information and not legal advice; applicability and current obligations should be verified against controlling regulations and current agency guidance.

Who it's relevant to

Federal agencies
Federal agencies are the primary entities covered by Section 508. They must ensure the ICT they develop, procure, maintain, or use provides individuals with disabilities access comparable to that available to others, and they typically rely on the U.S. Access Board's standards and federal guidance to determine how to meet these obligations.
Federal employees and members of the public with disabilities
Section 508 is intended to benefit disabled federal employees who use agency systems as well as members of the public who access federal information and services. The law's comparable-access requirement is what gives these users a basis to expect that government technology will work for them.
Vendors and contractors selling to the federal government
Companies that supply ICT to federal agencies commonly need to demonstrate that their products align with applicable accessibility requirements, since agencies must consider accessibility when procuring technology. This makes Section 508 relevant even to organizations that are not themselves directly covered by the statute.
Accessibility and compliance professionals
Accessibility engineers, compliance officers, and legal counsel working with or for federal agencies use Section 508 as a framework for evaluating digital products. They should distinguish it from the ADA and other authorities and verify current technical requirements against the Access Board's standards, consulting qualified legal counsel where specific obligations are in question.

Inside Section 508

Scope and Applicability
Section 508 of the Rehabilitation Act applies to US federal agencies, requiring that information and communication technology (ICT) they develop, procure, maintain, or use be accessible to people with disabilities, including federal employees and members of the public. It does not directly govern private businesses, though federal contractors and recipients of federal funds may encounter related obligations.
Relationship to the Rehabilitation Act
Section 508 is one provision within the broader Rehabilitation Act, which addresses disability rights in federal and federally funded contexts. It is distinct from Section 504 of the same Act, which more broadly prohibits disability discrimination in programs receiving federal financial assistance.
Technical Standards via the Access Board
The technical and functional requirements implementing Section 508 are established by the US Access Board. The Access Board's refresh of the ICT standards incorporated WCAG success criteria by reference as the benchmark for web content and certain software, aligning federal requirements with recognized international guidelines.
Covered ICT
Section 508 covers a range of information and communication technology, which can include websites, software applications, electronic documents, hardware, and multimedia used by covered federal entities.
Distinction from the ADA
Section 508 is separate from the Americans with Disabilities Act. Title II of the ADA applies to state and local governments and Title III to places of public accommodation, whereas Section 508 focuses on the federal government's own ICT.

Common questions

Answers to the questions practitioners most commonly ask about Section 508.

Does Section 508 apply to all businesses and private websites?
No. Section 508 applies to federal agencies and to information and communication technology (ICT) they develop, procure, maintain, or use, and it commonly extends to certain federal contractors and grant-related contexts. It is not a general mandate for all private-sector websites. Private businesses that are places of public accommodation are more often addressed under Title III of the ADA, while state and local government entities fall under Title II. Section 504 of the same Rehabilitation Act addresses programs receiving federal financial assistance. Because scope depends on your specific relationship to the federal government, consult qualified legal counsel for your situation. This is not legal advice.
Is Section 508 the same as WCAG?
No, though they are closely related. Section 508 is a US statutory requirement, and its implementing standards are maintained by the U.S. Access Board. The current Section 508 standards (the Revised 508 Standards, sometimes called the ICT Refresh) incorporate WCAG Level A and AA success criteria by reference as the technical baseline for web content and electronic documents. WCAG itself is a set of technical guidelines published by the W3C through the Web Accessibility Initiative. So WCAG supplies much of the technical detail, while Section 508 is the legal framework that adopts it in the federal context. Requirements can evolve through Access Board rulemaking, so verify the currently applicable version.
Which WCAG conformance level should we target to align with Section 508?
The Revised 508 Standards incorporate WCAG Level A and AA success criteria for covered web content and electronic documents, so AA is generally the level associated with Section 508 alignment. Level AAA is not typically required as a blanket standard. Keep in mind that meeting these success criteria addresses the technical baseline but does not by itself guarantee a fully usable experience for every user. Confirm the specific WCAG version currently referenced by the applicable Access Board standards for your project.
How do we document Section 508 conformance when procuring ICT?
Conformance is commonly documented using an Accessibility Conformance Report (ACR), often based on the Voluntary Product Accessibility Template (VPAT). Such a report describes how a product measures against the applicable standards, criterion by criterion. Because vendor-supplied reports vary in accuracy and completeness, agencies often supplement them with independent evaluation. A conformance report reflects a claim at a point in time and does not substitute for testing the product as deployed in your environment.
Is automated testing enough to confirm Section 508 conformance?
No. Automated tools detect only a portion of accessibility issues and cannot fully evaluate criteria that depend on context, meaning, or user interaction. A defensible evaluation generally combines automated testing with manual review and testing using assistive technologies such as screen readers and keyboard-only navigation. Relying on automated checks alone can leave significant barriers undetected.
What kinds of ICT beyond websites does Section 508 cover?
Section 508 addresses a broad range of information and communication technology, which can include web content, software applications, electronic documents, hardware, multimedia, and other electronic content used by covered federal entities. This means conformance efforts often extend beyond public websites to internal systems, documents, and procured products. Because the exact scope of covered ICT is defined in the Access Board standards and depends on how the technology is used, review the current standards and consult qualified counsel for specific determinations.

Common misconceptions

Section 508 applies to all businesses and websites in the United States.
Section 508 is directed at US federal agencies and their ICT. Private-sector obligations more commonly arise under the ADA or through contractual requirements when doing business with the federal government, rather than under Section 508 itself. Consult qualified legal counsel regarding which authority applies to a given entity.
Section 508 and the ADA are the same law or are interchangeable.
They are distinct. Section 508 is a provision of the Rehabilitation Act governing federal ICT, while the ADA is a separate civil rights law with Title II covering state and local government and Title III covering places of public accommodation. Their scope and enforcement differ.
Meeting Section 508 technical standards guarantees a fully accessible and legally compliant product.
Conformance with referenced technical criteria does not by itself guarantee a usable experience for all users or immunity from legal claims. Automated testing detects only a portion of potential issues, and manual and assistive technology testing are generally needed. Requirements also evolve through regulation and agency guidance.

Best practices

Confirm whether Section 508 actually applies to your organization, distinguishing it from ADA obligations, and consult qualified legal counsel about which authority governs your context.
Reference the current Access Board ICT standards, which incorporate WCAG success criteria, and verify you are working from the applicable version rather than assumptions about which criteria apply.
Combine automated testing with manual review and testing using assistive technologies, since automated tools detect only a portion of accessibility issues.
Address the full range of covered ICT that may be in scope, including websites, software, electronic documents, and multimedia, rather than focusing on web pages alone.
Treat conformance as necessary but not sufficient, and evaluate real-world usability for people with disabilities in addition to meeting technical criteria.
Monitor updates to Access Board rulemaking and agency guidance, since federal ICT requirements evolve over time.
