ACR: Accessibility Conformance Report (vs. VPAT)

man signing document

(Updated for 2023)

The Accessibility Conformance Report or ACR is a representation of how a product meets the applicable accessibility standards.

An ACR is the result of a completed VPAT® (Voluntary Product Accessibility Template).

The difference between VPAT and ACR is the source of moderate confusion so let’s unpack everything.

The Voluntary Product Accessibility Template or VPAT is just that — a blank template that can be filled out to account for that product or service’s state of accessibility.

Beyond addressing the product’s accessibility, an ACR contains the pertinent product information such as the name of the product, product description, applicable standards, evaluation methods used, etc.

Simply, an ACR is a completed VPAT (i.e., the blank template is filled out).

In the marketplace, the term VPAT dominates, even though it’s usage is technically incorrect because a VPAT is only a blank template.

You’ll often hear procurement departments ask for a VPAT but what they’re really asking for is an ACR.

Note: Per, “there are other possible methods to complete an ACR” but “the most common way an ACR is completed is by using the VPAT®”.

The Essential Information

At a minimum, an ACR must include:

  • Report Title: “[Company Name] Accessibility Conformance Report”
  • VPAT version
  • Name of Product (and version, if applicable)
  • Product description
  • Date of Publication
  • Contact information
  • Evaluation Methods Used
  • Applicable standards: WCAG 2.0, WCAG 2.1, Revised Section 508, EN 301 549

Recommended Best Practices

The Information Technology Industry Council or ITI (creators of the VPAT) also recommend the following best practices in creating an ACR:

  • Include a branded header with logo or entity information
  • Date changes if the report is revised
  • Any notes applicable to the product or report including links or product description
  • legal disclaimers

Completed VPAT

Of course, the main course — and the most important part of an ACR — is the filled-out table that addresses the product’s conformance with the applicable standard.

For each criterion under a standard, you must state whether the product supports, partially supports, does not support, or whether the criterion is not applicable to describe the level of conformance.

You can read more about what you need to complete a VPAT along with additional explanation on the difference between a VPAT vs. an ACR in my VPAT guide.

Not an Audit

An ACR is not an audit.

An audit goes into much greater detail than an ACR.

If you have an accessibility audit performed, you can usually get an ACR at a much lower cost, if not included with the price of the audit.

Third-Party Issuance

It’s optimal to have an independent, expert third-party expert specializing in digital accessibility issue your ACR vs. creating your own ACR in-house.

To stay competitive in 2021, your organization needs to have ACRs to send to procurement departments but they need to contain reliable and accurate information.

Unless your organization has an internal team consisting of a technical accessibility specialists, you won’t be able to produce a good ACR.

There are reputable third-party companies who can issue accurate ACRs for your organization.

VPAT / ACR services are offered by reputable companies but vetting providers is extremely important. The last thing you want to do is waste time and money paying thousands of dollars to a scam vendor.

For example, some accessibility overlay vendors (the ones that claim instant accessibility) market VPAT services. VPATs issued from an overlay vendor lack any credibility; you’d need to get another VPAT from a real, established company.


ACRs are typically not for websites or mobile apps but for products and, sometimes, services.

For example, software would be a prime example of when an ACR is called for.

However, per, an ACR may involve a website as part of the electronic content of a product or service.

“A Voluntary Product Accessibility Template (VPAT®) is a document that explains how information and communication technology (ICT) products such as software, hardware, electronic content, and support documentation meet (conform to) the Revised 508 Standards for IT accessibility.”

For non-product websites or apps, ask your accessibility provider for a conformance statement (that speaks directly to WCAG 2.0 AA or 2.1 AA) and/or certification.
