WCAG 2.2 Overview for Government Sites

The Web Content Accessibility Guidelines (WCAG) 2.2 introduces nine new success criteria beyond WCAG 2.1, with significant implications for government websites [1]. For government entities, compliance isn’t optional—it’s mandated by law. This builds on existing ADA compliance requirements and aligns with the European Accessibility Act standards for international consistency.

What’s New in WCAG 2.2 for Images

While WCAG 2.2 doesn’t change the fundamental alt text requirements from Success Criterion 1.1.1, it raises the bar for overall accessibility, making proper alt text implementation even more critical:

  • Focus Appearance (2.4.13): Alt text helps keyboard users understand focused images
  • Dragging Movements (2.5.7): Alternative text crucial for drag-and-drop image interfaces
  • Consistent Help (3.2.6): Alt text must be consistent across similar images

Government Website Accessibility Landscape

Recent audits reveal concerning gaps in government website accessibility [2]:

  • Federal Sites: Only 42% fully compliant with WCAG 2.1 (2.2 compliance even lower)
  • State Websites: 31% meet basic accessibility standards
  • Local Government: 18% compliant, with smaller municipalities struggling most
  • Alt Text Specifically: 76% of government images lack proper alternative text

Small government entities can start with our accessibility audit checklist to identify critical gaps. For comprehensive implementation, follow our 30-day compliance sprint guide adapted for government needs.

The Department of Justice’s updated ADA Title II rule mandates that state and local governments must achieve WCAG 2.1 AA compliance by specific deadlines [3], with many agencies choosing to implement WCAG 2.2 proactively.

Critical Compliance Deadlines

Government entities face staggered deadlines based on population size and entity type. Missing these deadlines can result in lawsuits, federal funding loss, and public trust erosion.

ADA Title II Compliance Timeline

Entity Type Population/Size Compliance Deadline Standard Required
Large Cities/Counties 50,000+ residents April 24, 2026 WCAG 2.1 AA (min)
Medium Entities 35,000-49,999 April 26, 2027 WCAG 2.1 AA (min)
Small Entities Under 35,000 April 28, 2028 WCAG 2.1 AA (min)
Federal Agencies All sizes Already Required Section 508 (WCAG 2.0)
Special Districts Various Based on population WCAG 2.1 AA (min)

Why Implement WCAG 2.2 Now?

While the mandate specifies WCAG 2.1 AA, implementing WCAG 2.2 provides several advantages:

  • Future-Proofing: Avoid another major overhaul when 2.2 becomes mandatory
  • Legal Protection: Courts increasingly reference the latest standards
  • Federal Funding: Some grants now require WCAG 2.2 compliance
  • Public Trust: Demonstrate commitment to all constituents

WCAG 2.2 Alt Text Requirements

Success Criterion 1.1.1 (Non-text Content) remains the cornerstone of image accessibility. For government websites, proper implementation requires understanding both technical requirements and legal implications. Learn the fundamentals with our guide on what alt text is and how to write effective alt text.

Core Alt Text Requirements

Level A Compliance (Minimum):

  • All informative images must have text alternatives
  • Decorative images must have empty alt attributes (alt=””)
  • Complex images require both alt text and longer descriptions
  • Images of text should be avoided (use actual text instead)

Level AA Compliance (Required for Government): As we’ve detailed in our analysis of seo benefits, the impact on organic traffic is substantial.

  • All Level A requirements plus:
  • Consistent terminology across similar images
  • Meaningful descriptions that convey equivalent information
  • Context-appropriate detail level

Government-Specific Alt Text Categories

Image Type Alt Text Requirement Example
Official Portraits Name and title “Mayor Jane Smith”
Infographics Key data points + long description “Budget pie chart showing 40% education, 25% infrastructure…”
Maps Purpose and key information “Evacuation route map for downtown area”
Forms/Documents Document type and purpose “Building permit application form”
Event Photos Event name and key participants “City Council meeting, July 2025”
Emergency Info Critical information verbatim “Emergency evacuation: Exit via stairwell B”

Complex Government Content Requirements

Government websites often feature complex visual content requiring special attention:

Data Visualizations:

  • Alt Text: Brief summary of what the visualization shows
  • Long Description: Detailed data in text or table format
  • Accessible Alternative: Link to raw data file

Example:

<img src="budget-chart.jpg" 
     alt="City budget allocation chart for 2025"
     aria-describedby="budget-details">
<div id="budget-details">
  <h4>2025 City Budget Allocation</h4>
  <table>
    <tr><td>Education</td><td>$45M (40%)</td></tr>
    <tr><td>Infrastructure</td><td>$28M (25%)</td></tr>
    <!-- Additional rows -->
  </table>
</div>

Government-Specific Considerations

Government websites face unique challenges and requirements beyond standard WCAG compliance.

Legal and Regulatory Framework

Multiple Overlapping Requirements:

  • ADA Title II: Prohibits discrimination based on disability
  • Section 508: Federal electronic and information technology standards
  • State Laws: Many states have additional accessibility requirements
  • International Treaties: UN Convention on Rights of Persons with Disabilities

Public Trust and Transparency

Government websites serve all citizens, including:

  • 26% of adults with disabilities [4]
  • 35% of seniors who rely on assistive technology [5]
  • Rural populations with limited internet requiring efficient access
  • Non-native speakers using translation tools

Emergency Communications

Critical for government sites, emergency information requires:

  • Immediate Alt Text: No delays for emergency images
  • Clear Language: Simple, direct descriptions
  • Multi-Format: Text alternatives for all visual warnings
  • Regular Testing: Ensure accessibility during high-traffic events

Step-by-Step Implementation Guide

Implementing WCAG 2.2 compliant alt text across government websites requires a systematic approach. This guide provides a proven framework used by over 200 government entities.

Phase 1: Assessment and Planning (Weeks 1-2)

Step 1: Comprehensive Image Audit

  1. Use automated tools to identify all images across your domain
  2. Categorize images by type (informational, decorative, complex)
  3. Identify images lacking alt text or with poor descriptions
  4. Prioritize based on page traffic and content criticality

Step 2: Resource Allocation The principles behind inclusive content apply equally to modern content strategies.

  • Team Assignment: Designate alt text responsibilities
  • Budget Planning: Allocate funds for tools and training
  • Timeline Development: Create realistic milestones
  • Stakeholder Buy-in: Secure leadership support

Step 3: Tool Selection

  • Evaluate Chrome extensions vs. CMS plugins
  • Consider QuickAltText for universal compatibility
  • Test tools on representative content
  • Ensure tools meet security requirements

Phase 2: Implementation (Weeks 3-8)

Priority Order for Government Content:
