U.S. federal law requiring accessibility for government ICT, updated in 2018 to incorporate WCAG 2.0 Level AA.
Section 508 of the Rehabilitation Act requires federal agencies to make their electronic and information technology accessible to people with disabilities. But its impact extends far beyond government – any organization that contracts with federal agencies must also comply.
Enacted in 1998 and updated in 2018, Section 508 is more specific than the ADA about digital accessibility requirements. It directly references WCAG 2.0 Level AA as the technical standard, providing clear guidance that the ADA lacks.
Unlike ADA lawsuits which rely on civil rights claims, Section 508 violations can result in contract termination, federal funding loss, and procurement exclusion. For businesses working with government, Section 508 compliance isn't optional – it's a business requirement.
Section 508 coverage is broader than many realize:
Direct Coverage: - All federal agencies and departments - Federal contractors and subcontractors - Organizations receiving federal funding - State and local governments using federal funds for technology
Indirect Coverage: - Vendors selling to covered entities - Software and service providers to government - Educational institutions with federal contracts - Healthcare organizations with federal funding
The Procurement Impact: Federal agencies must consider accessibility in procurement decisions. Non-compliant vendors can be excluded from contracts worth billions annually. This creates market pressure for accessibility even in private sector sales.
State and Local Extensions: Many states have adopted Section 508-like requirements. California's Unruh Civil Rights Act, New York's accessibility laws, and similar state legislation often reference Section 508 standards.
Global Influence: Section 508's WCAG adoption influenced international standards like EN 301 549 (Europe) and JIS X 8341 (Japan). Compliance often satisfies multiple jurisdictions simultaneously.
The 2018 Section 508 refresh adopted WCAG 2.0 Level AA as the technical standard, providing specific, testable requirements:
Key Requirements: - 1.1.1 Non-text Content: Alt text for all meaningful images - 1.4.3 Contrast (Minimum): 4.5:1 contrast ratio for normal text - 2.1.1 Keyboard: All functionality available via keyboard - 2.4.1 Bypass Blocks: Skip links for navigation - 3.3.2 Labels or Instructions: Form fields properly labeled - 4.1.2 Name, Role, Value: Proper ARIA implementation
Additional 508 Requirements: - Closed Captions: All video content must include captions - Audio Description: Video with visual information needs audio description - Flashing Content: No content flashes more than 3 times per second - Electronic Documents: PDFs, Word docs, etc. must be accessible
Testing Requirements: Agencies must test with assistive technology, not just automated tools. This means actual screen reader testing, keyboard navigation verification, and user testing with people with disabilities.
Documentation: Section 508 requires formal accessibility conformance reports (ACRs) documenting compliance status. These detailed reports become part of procurement records.
Section 508 enforcement has real consequences, unlike the ADA's civil lawsuit model:
Federal Agency Enforcement: - Office of Management and Budget (OMB) oversight - General Services Administration (GSA) guidance and tools - Agency-specific accessibility officers and policies - Annual reporting requirements to Congress
Contractor Consequences: - Contract termination for non-compliance - Exclusion from future procurement opportunities - Requirement to remediate at contractor expense - Potential legal liability under contract terms
Recent Enforcement Actions: - GSA's Section508.gov provides compliance guidance and monitoring - Agencies increasingly require accessibility testing in acceptance criteria - Procurement officers trained to evaluate accessibility claims - Post-award monitoring and compliance verification
The Business Impact: Major contractors like Microsoft, Adobe, and IBM have invested millions in accessibility to maintain federal contracts. Smaller vendors increasingly face accessibility requirements in RFPs and contract terms.
Positive Trend: Rather than punitive enforcement, agencies increasingly work with contractors to achieve compliance. The goal is accessible technology, not contract penalties.
While both laws promote accessibility, they operate differently:
Legal Framework: - Section 508: Federal procurement law with specific technical standards - ADA: Civil rights law with general anti-discrimination requirements
Technical Standards: - Section 508: Explicitly requires WCAG 2.0 Level AA compliance - ADA: No specific technical standards (WCAG used as best practice)
Enforcement: - Section 508: Administrative enforcement through contract mechanisms - ADA: Private lawsuits and DOJ enforcement actions
Scope: - Section 508: Government and contractors only - ADA: All places of public accommodation (potentially all public-facing websites)
Documentation: - Section 508: Formal ACRs and detailed compliance reporting required - ADA: No specific documentation requirements (but helpful for defense)
Practical Overlap: Organizations subject to both laws should focus on WCAG 2.1 Level AA compliance (newer than Section 508's 2.0 reference). This satisfies Section 508 requirements and provides strong ADA defense.
Government accessibility audits are thorough and technical. Here's how to prepare:
Pre-Audit Preparation: - Conduct comprehensive WCAG 2.0 Level AA audit - Test with multiple screen readers (JAWS, NVDA, VoiceOver) - Verify keyboard navigation for all functionality - Review all electronic documents (PDFs, Word, Excel) - Prepare accessibility conformance report (ACR)
Common Audit Findings: - Inaccessible PDF documents (most common violation) - Missing or inadequate alt text - Keyboard navigation failures - Insufficient color contrast - Form labeling issues - Video content without captions
Documentation Requirements: - Detailed test results with assistive technology - Screenshots and video evidence of accessibility features - Code samples demonstrating proper ARIA implementation - User testing results with people with disabilities - Remediation plans for any identified issues
Ongoing Compliance: - Regular accessibility testing throughout development - Staff training on Section 508 requirements - Accessibility review process for all content updates - Vendor management for third-party components - Incident response plan for accessibility issues
