Section 508 Checklist for Federal Agencies — Complete Guide (2026 Update)
Section 508 of the Rehabilitation Act requires federal agencies to make their electronic and information technology (EIT) accessible to people with disabilities. In 2026, compliance means meeting WCAG 2.1 Level AA standards.
📌 What Is Section 508?
Section 508 was updated in 2017 to refresh the standards, aligning with WCAG 2.0 Level AA. In practice, federal agencies now follow WCAG 2.1 Level AA for full compliance. The law applies to all federal agencies, including contractors and organizations receiving federal funding.
