Automated Evaluation Tool

Software that automatically scans websites, applications, or documents to detect accessibility violations against standards such as WCAG or Section 508. Common examples include WAVE, axe, AChecker, and Lighthouse. While these tools can efficiently identify many technical barriers such as missing alt text or insufficient colour contrast, they typically detect only 30-40% of accessibility issues and cannot assess subjective aspects like clarity of content or ease of navigation with assistive technologies. Effective accessibility evaluation therefore combines automated tools with manual testing and user evaluation.
