Accessibility Remediation

What It Means

Accessibility remediation involves modifying digital content so it can be used by people with disabilities. This process ensures websites, documents, videos, and audio files meet standards like WCAG (Web Content Accessibility Guidelines). Compliance with WCAG is often required under laws such as the ADA, Section 508, and the AODA.

What Can Be Remediated

Remediation applies to websites, documents, videos, and audio files — each with specific techniques and tools.

Websites

Remediation for websites includes improving compatibility with screen readers, using proper HTML heading structure, providing alt text for images, ensuring keyboard accessibility, fixing color contrast issues, and making layouts responsive.

Documents

PDFs and Office files can be remediated using accessibility checkers and manual updates. This includes tagging content correctly, structuring tables for screen readers, and adding descriptive text where needed.

Videos

Videos should include captions for dialogue and audio descriptions for visual content that is necessary for understanding.

Audio Files

Audio-only content such as podcasts must include accurate transcripts to ensure accessibility for deaf or hard-of-hearing users.

Critical Steps in the Remediation Process

The remediation process typically follows three key phases: auditing, implementing fixes, and ongoing monitoring.

1. Accessibility Audit

Begin by identifying accessibility barriers through a manual review, automated tools, or a hybrid approach. An audit assesses conformance with WCAG and establishes the scope of required fixes.

2. Implementing Fixes

Address issues found during the audit. This may involve code changes, content updates, or using accessibility tools. Methods vary by content type but aim for full compatibility with assistive technologies.

3. Ongoing Monitoring

Regularly check your content for new accessibility issues, especially after updates. Automated scans and manual checks should be part of a long-term maintenance plan. This supports legal compliance and prevents regressions.
