Case Study
Accessibility audit
Comprehensive accessibility evaluation and remediation of a public-facing web application
Overview
A government agency needed their citizen-facing portal to meet WCAG 2.2 AA standards before a regulatory deadline. The audit uncovered 142 accessibility issues ranging from missing alt text to complex keyboard navigation failures.
Challenge
The application had been built without accessibility considerations. Screen reader users could not complete core tasks. Color contrast ratios failed on 40% of text elements. Interactive components lacked proper ARIA labels, and focus management was broken throughout.
Process
The audit combined automated scanning with manual testing across five assistive technologies. Each issue was categorized by severity, WCAG criterion, and estimated remediation effort. User testing with four participants who use assistive technology daily validated the findings.
Solution
A prioritized remediation roadmap addressed critical issues first — keyboard navigation, screen reader compatibility, and color contrast. Component-level fixes were documented as reusable patterns. Training sessions equipped the development team to maintain accessibility going forward.
Results
All 142 issues were resolved within the deadline. The application achieved full WCAG 2.2 AA compliance. Post-remediation testing with assistive technology users showed a task completion rate increase from 34% to 96%. The agency received commendation for their accessibility standards.
