There is no official certification for ADA compliance. The Americans with Disabilities Act (ADA) is a law that prohibits discrimination based on disability. The Web Content Accessibility Guidelines (WCAG) contains guidelines/documents for web accessibility, which are published by World Wide Web Consortium (W3C) via their Web Accessibility Initiative (WAI). Neither the government, the guidelines, the organization, nor the initiative offer any official certification. Third-party tools are available for WordPress that test the conformance level of the outlined WCAG standards. Testing — combined with human evaluation — help determine if a website is “compliant”. Based on the results, there are third-party companies that are willing to “certify” the WordPress website as being compliant.
