A clear accessibility statement helps buyers and vendors evaluate digital products against recognised standards by summarising scope, test methods, evidence, and remediation plans. A VPAT and its completed form, an ACR — the Voluntary Product Accessibility Template and the Accessibility Conformance Report — provide that standardised format, enabling procurement teams to compare options objectively and giving vendors a dated, auditable record to prioritise fixes and demonstrate inclusive design.
VPAT Defined
Definition: A Voluntary Product Accessibility Template is a standardised form that vendors complete to describe a product’s accessibility.
- Completed form: When filled out, the VPAT becomes an Accessibility Conformance Report (ACR) that documents test results and evidence.
- Standards covered: Commonly maps product conformance to WCAG, Section 508, EN 301 549, or international variants.
- Purpose: Helps procurement teams compare accessibility claims and make informed purchasing decisions.
- Typical users: Software vendors, government buyers, and private-sector procurement officers.
- Contents: Includes product details, evaluation methods, and conformance entries (e.g., Supports; Partially supports; Does not support; Not applicable).
- Limitations: Serves as a transparency tool, not a formal certification.
- Best practice: Producing a credible ACR usually requires expert accessibility testing.

Using a VPAT or ACR to Drive Accessibility Improvements
Overview
A VPAT (Voluntary Product Accessibility Template) and its completed form, the ACR (Accessibility Conformance Report), are practical tools that translate technical accessibility testing into a clear, comparable format for buyers and stakeholders.
Key reasons to have one
- Procurement readiness: Buyers and procurement teams use ACRs to compare accessibility claims consistently during RFPs and vendor evaluations.
- Risk reduction: Documenting test methods and results demonstrates due diligence and can lower legal and compliance exposure.
- Market access: Public-sector contracts and many enterprises require documented accessibility evidence; an up-to-date ACR improves chances of winning bids.
- Product improvement: Preparing a VPAT/ACR forces teams to test core user flows, priorities fixes, and track remediation over time.
- Customer trust: Transparent reporting builds credibility with procurement officers, accessibility reviewers, and end users.
Best practices
- Use the VPAT edition that matches buyer requirements (e.g., WCAG, Section 508, EN 301 549).
- Describe testing methods (automated scans, manual review, user testing) and include sample evidence.
- Update the ACR with each major release and involve accessibility experts for credible results.
How does a VPAT demonstrate conformance with WCAG standards?
Definition
A Voluntary Product Accessibility Template (VPAT) for WCAG compliance is a standardised form vendors use to describe how a website, application, or digital product aligns with the Web Content Accessibility Guidelines. The template breaks WCAG success criteria into a consistent checklist so each item can be marked as Supports, partially supports, Does not support, or not applicable, and paired with concise evidence.
From VPAT to ACR
When a VPAT is completed after a thorough accessibility assessment, it becomes an Accessibility Conformance Report (ACR). The ACR is the finished, evidence-based document procurement teams and reviewers used to understand which WCAG criteria are met, which need work, and the scope of testing performed.
Editions and versions
Modern VPAT releases (for example, VPAT 2.5) come in multiple editions to match regulatory needs: a WCAG-focused edition, a Section 508 mapping for U.S. federal procurement, an EN 301 549 mapping for European public tenders, and an international edition that consolidates mappings for cross-region use. Selecting the right edition ensures the report aligns with buyer expectations.
What to include?
A credible WCAG VPAT/ACR lists the product version, scope of testing, date, criterion-by-criterion results, representative examples of findings, and any exclusions or limitations. Clear notes on unresolved issues help readers assess risk.
Testing approach and upkeep
Excellent reports combine automated scans, manual inspections, assistive technology checks, and real user scenarios. Keep the ACR current after major releases and document methods and evidence to maintain credibility and support procurement decisions.
Types of VPATs
| VPAT Type | Primary Standard/Framework | Purpose & Use Case | Region/Market Focus |
| VPAT 508 | Section 508 of the U.S. Rehabilitation Act | Demonstrates compliance with accessibility requirements for federal procurement in the United States. | United States (federal agencies, contractors) |
| VPAT WCAG | Web Content Accessibility Guidelines (WCAG) 2.x | Used to show conformance with international web accessibility standards, often required by organizations worldwide. | Global (web-based products/services) |
| VPAT EU | EN 301 549 (European accessibility standard) | Required for ICT products and services sold in the European Union, aligning with EU accessibility directives. | European Union |
| VPAT INT | International accessibility standards (general) | Provides a flexible template for documenting accessibility compliance outside the U.S. and EU. | Global (non-U.S./EU markets) |
✅ Key Notes for Choosing the Right VPAT
- U.S. federal contracts → VPAT 508 is mandatory.
- Web-based products → VPAT WCAG is most widely recognized.
- European procurement → VPAT EU aligns with EN 301 549.
- Other international markets → VPAT INT provides a general framework.
⚠️ Risks & Considerations
- Incomplete VPATs can harm credibility; buyers expect detailed testing results, not vague claims.
- Jurisdiction mismatch (e.g., using VPAT 508 for EU contracts) can lead to rejection.
- Updates matter: VPAT versions are revised regularly (latest is VPAT 2.5Rev, April 2025), so using outdated templates may cause compliance issues.
📝 Common VPAT Mistakes to Avoid – Checklist
- Clarity of Responses
- Avoid vague answers like “Supports” without explanation.
- Provide evidence or examples of testing results.
- Template Accuracy
- Use the correct VPAT type (508, WCAG, EU, INT) for the target market.
- Confirm you’re working with the latest version (e.g., VPAT 2.5Rev).
- Evidence of Testing
- Document actual accessibility testing outcomes.
- Do not rely on generic or copied language.
- Transparency in Compliance
- Acknowledge partial support or limitations honestly.
- Avoid overstating compliance, as it reduces credibility.
- Regular Updates
- Revise the VPAT when product features change.
- Update references to match evolving accessibility standards.
- Market-Specific Requirements
- Tailor the VPAT to regional procurement rules.
- Ensure alignment with Section 508 (U.S.), EN 301 549 (EU), or WCAG (global web).
✅ Conclusion
To summarize, preparing a VPAT demands precision, transparency, and alignment with the correct accessibility standards. Avoiding vague responses, outdated templates, and overstated compliance helps maintain credibility with procurement teams. Regular updates and evidence-based documentation strengthen accessibility claims. By following best practices, organizations can demonstrate genuine commitment to inclusivity.
