Accessibility testing is the practice of evaluating digital products—such as websites, applications, and software—for usability by people with disabilities. It involves identifying and resolving barriers that could hinder access for users with visual, auditory, motor, or cognitive impairments.
This skill is essential for ensuring compliance with accessibility standards including WCAG (Web Content Accessibility Guidelines), Section 508, and ADA requirements. Professionals perform both manual evaluations and automated scans to assess navigation, screen reader compatibility, keyboard accessibility, color contrast, and alternative text for images.
- Conduct manual and automated audits using tools like Axe, WAVE, and Lighthouse
- Verify compatibility with assistive technologies such as screen readers and voice control software
- Test keyboard navigation and focus management in web and mobile interfaces
- Ensure proper semantic HTML structure and ARIA label implementation
- Review multimedia content for captions, transcripts, and audio descriptions
- Document accessibility issues and provide actionable remediation guidance
Accessibility testing is commonly used by QA analysts, UX designers, front-end developers, and compliance officers in industries including government, healthcare, education, and technology. Employers seek professionals who understand inclusive design principles and can integrate accessibility checks into development workflows.
Individuals with this skill are expected to interpret accessibility guidelines, simulate user experiences with assistive tools, and advocate for inclusive design. Proficiency often includes familiarity with automated testing libraries, browser developer tools, and accessibility APIs. Strong attention to detail and empathy for diverse user needs are critical traits for effective accessibility testing.
