Explore Digital Accessibility Regulations

Section 508 is an amendment to the Rehabilitation Act of 1973 that requires U.S. federal agencies to ensure their Information and Communication Technology (ICT) is accessible to people with disabilities. The current standard incorporates WCAG 2.0 Level AA, helping provide equal access to digital information and services.

What Is Section 508?

Section 508 applies whenever federal agencies develop, purchase, maintain, or use digital technology, including websites, software, documents, mobile applications, and multimedia. It also impacts organizations that provide digital products or services to the federal government.

Who Must Comply?

Section 508 directly applies to U.S. federal agencies and indirectly affects vendors and contractors that develop or supply ICT solutions to the federal government. Vendors are often required to demonstrate accessibility through a Voluntary Product Accessibility Template (VPAT) or Accessibility Conformance Report (ACR).

What Does Section 508 Cover?

Section 508 applies to a wide range of digital assets, including:

• Public websites and web applications
• PDFs, Word documents, spreadsheets, and presentations
• Software and mobile applications
• Email communications
• Online learning platforms
• Employment application systems
• Audio and video content
• Hardware interfaces and kiosks

Accessibility Requirements

Section 508 incorporates WCAG 2.0 Level AA, which is based on four core accessibility principles:

• Perceivable – Information must be presented in ways users can perceive.
• Operable – Interfaces must be usable with keyboards and assistive technologies.
• Understandable – Content and navigation should be clear and predictable.
• Robust – Content should work reliably with current and future assistive technologies.

Many organizations now target WCAG 2.1 or 2.2 Level AA to support broader accessibility goals and future compliance.

How Does Section 508 Differ from the ADA?

While both promote digital accessibility, they apply to different sectors.

• Section 508 applies to U.S. federal agencies and government procurement.
• ADA applies to state and local governments, public accommodations, and many private businesses.

Organizations often follow WCAG Level AA to help satisfy the accessibility expectations of both standards.

What Is a VPAT?

A Voluntary Product Accessibility Template (VPAT) is a document used to describe how well a product conforms to accessibility standards such as Section 508. Once completed, it becomes an Accessibility Conformance Report (ACR) and is commonly requested during government procurement.

Best Practices for Section 508 Compliance

• Use semantic HTML and proper heading structure.
• Provide alternative text for images.
• Ensure full keyboard accessibility.
• Maintain sufficient color contrast.
• Use descriptive link text.
• Create accessible forms and documents.
• Test with assistive technologies and manual accessibility reviews.

Why Section 508 Compliance Matters

Meeting Section 508 requirements helps organizations create more inclusive digital experiences, reduce accessibility barriers, support government procurement requirements, and demonstrate a commitment to accessibility and equal access for all users.
