Measuring Accessibility: Metrics, Dashboards, and Proving Audit Impact to Stakeholders

There is one question that always surfaces after an auditor delivers their report: "How much progress have we made?"

This question comes from project managers wanting to know if their developer team is performing well. From directors needing to present progress to the board. From vendors wanting to prove their product outperforms competitors. And from budget holders questioning whether the investment in accessibility is truly delivering results.

A blind auditor who can only find problems but cannot communicate progress in a language management understands will always struggle to retain long-term contracts. This is why the ability to measure and report audit impact is the final — and perhaps most strategic — skill every Access Squad member must master.

The Problem with Popular "Accessibility Scores"

Before discussing good metrics, it's important to understand why the most commonly used metrics are actually misleading.

Lighthouse Score (0-100): It's entirely possible to achieve a Lighthouse score of 95 while the page remains completely unusable by JAWS users. This score only measures automatically detectable issues — approximately 30% of real problems.

"WCAG 2.2 Level AA Compliant": This claim is frequently misused. A product can claim "compliance" based on a partial or outdated evaluation. Without a transparent methodology, the claim is meaningless.

"0 Errors from Axe DevTools": An automated tool showing zero errors is only a starting point, not a finish line. As discussed in our audit methodology article — machines only catch 30% of issues.

Good metrics must reflect the real experience of users with disabilities, not merely the state of the code.

A Framework for Meaningful Accessibility Metrics

Cruse & Boudreau in Inclusive Design for Accessibility define that measuring accessibility progress must go beyond mere compliance — it must reflect real changes in experience, process, and culture.

Here are three recommended metric layers:

Layer 1: Issue Metrics

These are the most direct and easily quantifiable metrics from an audit report.

Metric	How to Measure	Example Target
Total Issues Found	Total bugs in the initial audit report	Baseline: 47 issues
Issues per Severity	Blocker / Critical / Major / Minor	3 Blockers, 8 Criticals, 22 Majors, 14 Minors
Issues Resolved	Issues fixed and verified via retest	Sprint 1 Target: 3 Blockers → 0
Regression Rate	New issues appearing in subsequent audit vs previous	Target: < 5 new issues per 6-month cycle
Coverage	Percentage of critical flows audited	Target: 100% critical flows, 70% secondary pages

Layer 2: Conformance Metrics

Higher than mere issues, these measure how far the product meets WCAG standards.

Metric	How to Measure
SC Pass Rate	Percentage of relevant WCAG Success Criteria met
Level A Conformance	What % of all Level A SCs are currently met?
Level AA Conformance	What % of all Level AA SCs are currently met?
Pages Fully Conformant	How many pages in the total sample have zero issues?

Example conformance progress report:

INITIAL AUDIT (Jan 2026):    SC Level A Pass Rate: 61%  |  AA Pass Rate: 44%
RE-AUDIT SPRINT 1 (Mar):     SC Level A Pass Rate: 89%  |  AA Pass Rate: 71%
RE-AUDIT SPRINT 2 (Jun):     SC Level A Pass Rate: 97%  |  AA Pass Rate: 88%
END-OF-YEAR TARGET:          SC Level A Pass Rate: 100% |  AA Pass Rate: 95%

This format is easy to present to management and shows a clear improvement trend.

Layer 3: Process & Culture Metrics

These are long-term metrics measuring whether accessibility has truly been embedded in the organization.

Metric	How to Measure
Time to Fix	Average days between a bug being reported and verified as fixed
Shift-Left Rate	Percentage of issues found in design/development phase (before release) vs post-release
Team Training Coverage	Percentage of developer/design team members who completed basic accessibility training
Accessibility Debt Trend	Are fewer issues entering the backlog than are being resolved each sprint?

Building a Simple Accessibility Dashboard

No expensive tools required. An effective accessibility dashboard can be built with a simple spreadsheet or Notion, as long as the information is well-structured.

Required Dashboard Components

1. Executive Summary (One Page) For the CEO or director who doesn't have time to read a 30-page report:

• Current conformance status (as a percentage)
• Number of remaining Blockers
• Progress trend (up/down from previous audit)
• Estimated time to achieve full Level AA compliance

2. Issue Tracker per Sprint For project managers and developer teams:

• Issue table categorized by severity
• Status of each issue: Open / In Progress / Fixed / Verified / Won't Fix
• Assignee and target date

3. Page Heatmap A visual showing which pages have the most vs fewest issues — helping prioritize areas needing immediate attention.

4. Time-Series Trend Chart A graph showing total issue count over time — ideally showing a steadily declining curve each sprint.

Communicating Business Impact: The Language Stakeholders Understand

This is the auditor's highest communication skill. Business stakeholders are not interested in "SC 4.1.2 Name, Role, Value Level A" — they care about money, risk, and reputation.

The Business Impact Formula

Every Blocker you verify as fixed can be communicated using this formula:

"Fixing [issue name] opens access to [critical feature] for an estimated [X% of the user population], potentially adding [estimated transactions/conversions] and reducing the risk of [legal action/regulatory fines]."

Real-world example:

"Before the audit, the 'Pay Now' button on the checkout page was inaccessible via keyboard. After the remediation we recommended was implemented and verified, an estimated 200,000 users with motor and visual disabilities in Indonesia can now complete transactions independently. Based on your average transaction value, this potentially unlocks [X] in new revenue."

Risk Language for Legal Stakeholders

"A product that does not meet WCAG 2.2 Level AA standards risks violating the European Accessibility Act 2025 for the European market, and potentially becoming the subject of ADA Title III litigation in the US market. This audit report documents 3 Blockers which, if left unaddressed, represent direct violations of SC 2.1.1 and 4.1.2 — two criteria most frequently cited in accessibility lawsuits."

Recommended Reporting Cycle

As an Access Squad consultant, recommend the following reporting schedule to clients:

Frequency	Report Type	Audience
After each Sprint	Bug Verification Report (retest of fixed issues)	Developer Team
Monthly	Progress Dashboard Update (issue + conformance metrics)	Project Manager
Quarterly	Executive Summary (business impact + trends)	Director / CEO
Annually	Full Re-Audit + Accessibility Statement Update	All Stakeholders
