How to Choose an ADA-Compliant Web Design Agency

Choosing the right ADA-compliant web design agency can be the difference between genuine accessibility and a costly failure. Here are the key criteria to evaluate.

First, verify credentials. Look for team members holding IAAP certifications — CPACC (Certified Professional in Accessibility Core Competencies) or WAS (Web Accessibility Specialist). Ask about their experience with manual testing, screen reader evaluation, and whether they employ people with disabilities in their testing process.

Second, ask about their methodology. A credible agency should describe a process that includes automated scanning (using tools like axe or WAVE), manual testing with keyboard navigation and screen readers, and real-user testing with people who have disabilities. If they mention only automated tools, that is a red flag.

Third, examine their portfolio for accessibility. Use a screen reader or browser developer tools to check their previous work. Do the sites have proper heading hierarchy? Alt text on images? Keyboard-navigable forms and menus? An agency's own website should also be accessible.

Fourth, clarify what WCAG conformance level they target. Most legal requirements reference WCAG 2.1 or 2.2 Level AA. Be wary of agencies that promise "full compliance" without specifying a standard.

Fifth, discuss ongoing support. Accessibility is not a one-time fix. Content changes, new features, and third-party integrations can introduce new barriers. A good agency offers monitoring retainers and training for your content team.

Red flags to watch for: agencies that recommend overlay widgets as a primary solution, those that guarantee "100% ADA compliance" (no tool can guarantee this), agencies that rely solely on automated testing, and firms that cannot name specific WCAG criteria.
