Accessibility Hub: Section 508 (United States)

Section 508 of the Rehabilitation Act is a U.S. federal accessibility requirement for information and communication technology (ICT). This page provides a practical overview of what Section 508 typically means for websites, documents, applications, and other digital content.

Section 508 at a glance

What it is: Section 508 requires U.S. federal agencies to ensure that ICT they develop, procure, maintain, or use is accessible to people with disabilities.
Who it benefits: The requirement covers both federal employees and members of the public seeking information or services.
Digital accessibility standard: The “Revised 508 Standards” (the ICT refresh) incorporate WCAG 2.0 Level AA by reference for web content and also apply WCAG 2.0 AA success criteria to many types of non-web electronic content (like office documents and PDFs).
Beyond websites: Section 508 is broader than web pages—it addresses accessibility for electronic content, software, support documentation, and certain hardware/ICT functions.
Accessibility is ongoing: New releases, content updates, and third-party tools can introduce barriers over time, so ongoing checks are essential.

When Section 508 applies

Federal agencies: Section 508 applies to U.S. federal departments and agencies when they develop, procure, maintain, or use ICT.
Public-facing digital services: If a federal agency provides websites, forms, documents, or digital services to the public, those experiences are generally expected to meet Section 508 requirements.
Internal digital services: Section 508 also covers ICT used by federal employees (for example: intranets, internal systems, HR tools, and collaboration tools).
Vendors and contractors: If you sell digital products or services to the U.S. federal government, accessibility requirements are typically included in procurement and contracting processes. In practice, this often means providing accessibility documentation and demonstrating conformance.

What Section 508 covers
(in digital accessibility terms)

Baseline: Section 508’s Revised Standards incorporate WCAG 2.0 Level AA as the primary accessibility benchmark for web content and many types of electronic content.
Recommended best practice: While WCAG 2.0 AA is the common legal baseline referenced in Section 508 guidance, many teams aim for WCAG 2.1 or 2.2 to improve mobile accessibility and future-proof digital experiences.
Consistency matters: If a component or pattern is reused across a site or product, it needs to be accessible everywhere it appears.
Not a one-time effort: Conformance needs to be maintained as content changes, features launch, and vendors/tools are introduced or updated.

Procurement and accessibility documentation

When Section 508 is tied to procurement, teams are often asked to provide accessibility documentation that explains how a product or service conforms to applicable requirements (for example, a Voluntary Product Accessibility Template (VPAT) / Accessibility Conformance Report (ACR) and supporting test evidence). Plan for this early—especially if you’re using third-party tools or selling into federal environments.

Define scope clearly: What pages, user journeys, documents, and platforms are included.
Document known gaps: Track issues, impacted users, severity, and which WCAG criteria are affected.
Provide a remediation plan: Include timelines, owners, and how fixes will be validated.
Offer an accessible alternative: Provide a way to complete the task or obtain information if a barrier remains (and ensure support teams know the process).

Practical requirements for websites and digital content

In practice, Section 508-aligned digital accessibility work usually looks like building and maintaining key user journeys (navigation, content, forms, and workflows) to meet WCAG 2.0 AA expectations and ensuring documents and non-web content are accessible where required.

If something can’t be made fully accessible
(exceptions and alternatives)

If you discover a barrier that can’t be remediated immediately (or cannot be remediated due to constraints), plan how users will complete the task without being blocked. In Section 508 programs, this typically means documenting the issue and providing an accessible alternative path while remediation is planned.

Document the rationale: What prevents remediation now (for example: vendor limitation, legacy system constraint), and the decision owner.

Describe user impact: Who is affected and what task is blocked or degraded.

Provide an accessible alternative: An accessible version, assisted completion, or another method that offers comparable access.

Set a review date: Revisit exceptions regularly to reduce long-term risk and regression.

Core WCAG themes to watch for:

Perceivable: Provide text alternatives for non-text content; ensure sufficient color contrast; don’t rely on images alone to convey information.

Operable: Ensure everything works with a keyboard; visible focus is present; avoid time limits that can’t be adjusted.

Understandable: Use clear labels and instructions; consistent navigation; predictable interactions; helpful error messages.

Robust: Use semantic markup so assistive technologies can interpret content reliably; avoid misusing ARIA.

Content author requirements

Headings and structure: Use headings in order (H1 → H2 → H3) and keep sections short and scannable.

Links: Use descriptive link text that explains the destination or action (avoid “click here” or raw URLs).

Images: Write alternative text that communicates purpose and meaning. Decorative images should have empty alt text.

Lists: Use real lists for list content (instead of manual line breaks or dashes).

Tables: Use tables only for data; include clear column/row headers and avoid merged cells when possible.

Documents: Default to accessible web pages when you can. If you must publish a PDF or Office file, ensure it has a logical reading order, proper headings, meaningful link text, and is usable with a keyboard and screen reader.

Video and audio: Provide accurate captions. Where needed, provide transcripts and/or audio description for important visual information.

Testing and release expectations

Minimum manual checks: Keyboard-only pass + a quick screen reader smoke test on key templates/flows.
Automated checks: Run an automated scan and resolve high/critical issues before publishing.
Regression checks: Re-test affected templates/components when navigation, styles, or shared component libraries change.
Document decisions: If something cannot be made fully accessible, document the reason, the impact, and the alternative provided (for example, an accessible version or an alternate way to complete the task).

How 4Point can help

If you’re unsure how Section 508 and WCAG apply to your organization—or what you need for an upcoming procurement, audit, or release.

Start with an accessibility audit. 4Point can run a practical audit to establish a baseline, identify the highest-risk barriers, and give you a prioritized remediation roadmap.

Scoping session: confirm which forms are in scope, the number to be reviewed, and the accessibility standard(s) to assess against.
Forms accessibility audit: review an agreed number of forms and document accessibility gaps.
Conformance report and prioritization: provide conformance findings, severity ratings, and a recommended fix order.
Recommendations and remediation plan: share recommendations for addressing identified gaps and provide a statement of work for remediation of the audited forms (remediation is not included in the audit engagement).

Next step: Share what you’d like reviewed (for example: a set of pages, forms, documents, videos, or a key user journey) and the platforms involved. We’ll confirm the approach and provide a prioritized findings summary with recommended fixes.
