How to Build an Accessibility Audit Trail Your Legal Team Will Use

Q: What should an accessibility compliance report include?

A compliance report should include current scan results, historical progress data, open issues by severity with remediation timelines, completed fixes, and a clear statement of known limitations and planned improvements.

A practical guide to documenting your accessibility compliance journey — from automated scans to issue timelines to the reports regulators care about.

February 12, 202610 min read

Most accessibility discussions focus on finding and fixing issues. But there's a critical piece many teams overlook: documenting the work. When legal questions arise — and with increasing regulatory enforcement, they do — having a clear record of what you tested, what you found, and how you responded matters as much as the fixes themselves.

An accessibility audit trail isn't about proving your site is perfect. No site is, and regulators know that. It's about demonstrating a good-faith effort: that you're aware of accessibility requirements, actively testing, fixing issues on a reasonable timeline, and transparent about what still needs work.

This guide covers what to document, how to structure it, and how to turn raw scan data into the kind of compliance evidence legal teams and regulators actually want to see.

The Business Case

Why documentation matters more than perfection

Regulatory guidance increasingly emphasizes ongoing effort over point-in-time compliance. The DOJ's April 2024 ADA rule focuses on whether organizations have reasonable timelines for addressing barriers. The European Accessibility Act similarly expects documented compliance processes, not just compliant websites.

In practice, this means two organizations with identical accessibility scores can face very different legal outcomes. The one with documented testing history, issue timelines, and remediation plans demonstrates good faith. The one with no documentation has no evidence of effort.

Courts consider ongoing effort, not just current compliance state
Documented remediation plans can reduce legal exposure
Regulatory frameworks (ADA, EAA) expect process documentation
94.8% of sites have WCAG failures — perfection isn't the standard

Core Components

What your audit trail should include

Scan history with timestamps

Every automated scan should be recorded with its date, scope (pages tested), and results summary. This creates a baseline and shows testing frequency. Regular scanning — weekly at minimum — demonstrates active monitoring.

Tip: Store raw scan data, not just summaries. You may need to reference specific findings later.

Issue lifecycle tracking

For each issue found, track when it was first detected, its severity, the assigned owner, remediation deadline, and resolution date. This timeline shows how quickly your team responds to accessibility barriers.

Tip: Use severity-based SLAs: critical issues within 7 days, serious within 14, moderate within 30, minor within 90.

Remediation evidence

When issues are fixed, document what changed and when. Link fixes to specific scan results showing the issue resolved. This connects your effort to measurable outcomes.

Tip: Scan comparison reports (before vs after) are powerful evidence of remediation.

Manual testing records

Automated tools catch approximately 40% of WCAG issues. Document your manual testing efforts too: keyboard navigation testing, screen reader testing, cognitive accessibility review. This shows awareness of automation limitations.

Tip: Keep a checklist of manual tests performed, with dates and findings, even if informal.

Known limitations and plans

Be transparent about issues you know about but haven't fixed yet. Documenting known limitations with planned remediation dates is far better than undocumented gaps — it shows awareness and intent.

Tip: Update your accessibility statement to reflect current known issues and your timeline for addressing them.

Compliance Reports

Structuring reports for different audiences

For legal teams

Evidence of ongoing effort, risk assessment, remediation timelines

Executive summary with compliance score trend
Open issues by severity with assigned deadlines
Historical progress (issues found vs fixed over time)
Documentation of testing methodology and frequency
Known limitations with planned remediation dates

For development teams

Actionable issue details, code-level fixes, priority guidance

Issues grouped by component or page template
Framework-specific code fix suggestions
Priority ranking by user impact and legal risk
Regression alerts when new issues appear
Links to relevant WCAG success criteria

For executives and stakeholders

Progress overview, risk posture, resource allocation justification

Compliance score with month-over-month trend
Top-level issue counts by severity
Remediation velocity (how fast issues get fixed)
Comparison against industry benchmarks
Budget and resource recommendations

Pitfalls

Common audit trail mistakes

Only documenting when things go wrong

Instead: Document continuously — regular scans, even when clean, show ongoing monitoring.

Relying solely on automated scan results

Instead: Include manual testing records. Regulators know automated tools catch only ~40% of issues.

No severity-based timelines

Instead: Set SLAs by severity. Treating all issues equally suggests no prioritization strategy.

Hiding known limitations

Instead: Document them transparently. An accessibility statement with known issues shows maturity, not weakness.

Point-in-time audits only

Instead: Continuous monitoring trumps annual audits. Regular scans show sustained commitment.

Getting Started

Building your audit trail in practice

Start scanning regularly

Set up automated WCAG 2.2 scanning on a weekly or per-deployment schedule. This creates your baseline and establishes a testing cadence.

Establish issue ownership

Assign each accessibility issue to a team member with a severity-based deadline. Track who owns what and when it's due.

Track fixes across scans

Use scan comparison to verify fixes. When an issue disappears between scans, that's documented remediation evidence.

Publish an accessibility statement

Create a public accessibility statement that acknowledges your current state, documents known issues, and outlines your commitment to improvement.

Review and report monthly

Generate compliance reports monthly. Track your score trend, remediation velocity, and open issue count. Share with legal and leadership.

Frequently Asked Questions

What is an accessibility audit trail?

An accessibility audit trail is a documented record of your organization's accessibility testing, remediation efforts, and compliance progress over time. It includes scan results, issue timelines, fix documentation, and compliance reports. Think of it as the paper trail that proves you're taking accessibility seriously.

Why do legal teams need accessibility documentation?

Legal teams need documentation to demonstrate good-faith compliance efforts. In accessibility-related legal matters, courts and regulators consider whether an organization has been actively working to improve accessibility — not just whether the site is currently perfect. Documentation of ongoing testing, issue tracking, and remediation timelines provides this evidence.

What should an accessibility compliance report include?

A compliance report should include: current scan results with WCAG 2.2 AA coverage, historical progress data showing score trends, open issues organized by severity with remediation timelines, completed fixes with evidence, manual testing records, and a clear statement of known limitations with planned improvements.

How often should accessibility audits be documented?

Regular documentation is key. Automated scans should run at least weekly (ideally per deployment), with full audit documentation updated monthly. Major changes like redesigns, new features, or platform migrations should trigger additional documentation. Annual third-party audits complement but don't replace ongoing monitoring.

What's the difference between an audit trail and an accessibility statement?

An accessibility statement is a public-facing document that communicates your accessibility commitment, conformance level, and known limitations to users. An audit trail is internal documentation of your testing and remediation efforts. The statement draws from the audit trail but is simplified for public consumption. Both are important — the statement shows transparency, the trail provides legal evidence.
