What is WCAG Compliance?

Web Content Accessibility Guidelines (WCAG) are technical guidelines developed by the Worldwide Web Consortium (W3C) with the goal of providing a single shared standard for web content accessibility that meets the needs of individuals, organizations, and governments internationally. A website that is WCAG compliant will satisfy most requirements required for ADA Title III, Section 508, Canada ACA & AODA, and EU compliance.

“Real World” Website Accessibility Testing

Question: How do I know if my website is accessible? 

Answer: Start by asking experts with disabilities!  Criterion ensures your website’s ADA Website Compliance by including 2 senior application developers and 3 expert auditors with disabilities on every project team!

Avoid ADA Website Compliance Litigation

Question: Since 2001, how many clients have been sued due to ADA website accessibility non-compliance after retaining Criterion’s services?

Answer: Zero! 

On the other hand, relying on automated website accessibility scanning tools, website accessibility plug-ins, or website accessibility overlays will not mitigate your legal risks.  Learn more about the limitations of these shortcuts! Learn More.
