The WAVE Accessibility IMpact (AIM) score provides a measure of impact of page accessibility issues on users with disabilities. The WAVE tools reports an Automated AIM based upon:
These factors are all aligned with the results from the annual WebAIM Million analysis of 1,000,000 home pages to provide a comparative score from 1 to 10. A score of 5 indicates that the page's score is roughly average compared to web pages generally.
IMPORTANT: A high AIM Score does not necessarily indicate that the page is highly accessible or compliant with accessibility guidelines. Manual testing is always necessary to determine accessibility and compliance.
WebAIM can provides an Accessibility IMpact (AIM) assessment report for your web site. This report provides detailed WAVE data, your site's Automated AIM score (based on WAVE testing), a Manual Accessibility Impact Score (based upon high-level expert tester analysis of a sample of site pages), and tester feedback to give you deeper insights into the accessibility of your web site for users with disabilities.
