For federal contractors, accessibility is not a “nice-to-have.” It’s a procurement requirement that can determine whether your product is considered eligible for purchase. One of the most common ways agencies evaluate accessibility is through a VPAT® (Voluntary Product Accessibility Template), typically delivered as an Accessibility Conformance Report (ACR). Done well, a VPAT can accelerate procurement and reduce back-and-forth. Done poorly, it can raise red flags and stall deals.
This article explains what a VPAT is, when federal contractors need one, how it maps to WCAG and Section 508, and the practical steps to produce an ACR that stands up to scrutiny.
A VPAT is a standardized template used to document how a product conforms to accessibility requirements. The completed document is commonly referred to as an Accessibility Conformance Report (ACR). Federal buyers use ACRs to compare vendors and assess risk.
Important nuance: a VPAT is not a certification. It’s a structured, vendor-provided disclosure of conformance status and known gaps. Because it can influence purchasing decisions, it should be accurate, specific, and based on evidence.
In U.S. federal procurement, Section 508 is the legal and policy anchor for accessible ICT. Many ACRs also reference WCAG because WCAG success criteria are widely used to define testable web and software requirements.
If you’re building or selling web-based systems to federal agencies, your VPAT work should be informed by a strong understanding of Section 508 expectations. For a deeper overview of what “federal-ready” typically means, see Section 508 compliance: a practical guide to accessible federal-ready websites.
VPAT templates align to different standards and jurisdictions. The most common options include:
Federal contractors commonly use the Section 508 or INT versions, depending on agency expectations and whether the product is also sold internationally.
Procurement teams, accessibility specialists, or third-party reviewers often look beyond the “Supports / Partially Supports / Does Not Support” labels. They want clarity and verifiable detail.
“Supports” with no explanation is rarely persuasive. Strong ACRs explain how a criterion is met and where it applies. For example, instead of “Supports 1.1.1,” describe how images, icons, and charts are handled (and any exceptions, such as user-generated content).
Your ACR should state what was tested, including:
Agencies may ask how you tested. A credible VPAT is typically based on a mix of automated scanning and manual evaluation (keyboard, screen readers, focus order, forms, error handling, color contrast, etc.). If your product includes mobile experiences, align your approach with public-sector expectations; the methods described in Mobile app accessibility audit for public sector: a WCAG-aligned approach are a helpful benchmark.
Creating an ACR is easiest when you treat it as an output of your accessibility program—not a last-minute document. Here’s a practical sequence that works for many federal contractors.
List the user-facing pages, workflows, documents, and UI components included in scope. If there are separate admin portals, help centers, or PDF exports, decide whether they are part of the deliverable and document it clearly.
Most teams test against WCAG success criteria and map results to Section 508 reporting. Include:
Platforms like Corpowid (corpowid.ai) can streamline this work by running automated accessibility audits and ongoing monitoring, helping teams catch regressions before they become procurement blockers.
A VPAT is not a bug tracker; it’s a buyer-facing report. For each criterion that is partially supported, explain:
As you remediate, re-test and update the VPAT remarks so your report remains aligned to the shipped product. Treat the ACR as a living document tied to release cycles.
Many federal customers appreciate (and sometimes request) an accessibility statement that complements your VPAT by describing support channels, known limitations, and commitments. Tools that generate and manage statements—such as Corpowid’s accessibility statement capabilities—can help keep public-facing information consistent with your procurement documentation.
The most effective VPAT strategy is to reduce what you need to explain as “partially supports.” That comes from building accessibility into design and development: semantic structure, strong keyboard patterns, clear error messaging, and consistent components.
It also helps to align your approach with broader compliance trends. Even if your immediate goal is U.S. federal procurement, many contractors serve global customers too. Understanding cross-jurisdiction expectations (like EN 301 549 in Europe) can prevent duplicated work; see The EAA and BFSG: what they mean for digital accessibility and WCAG compliance for context.
For federal contractors, a VPAT is more than a form—it’s a transparency document that signals maturity, reduces procurement risk, and sets expectations for accessibility support. The fastest path to a strong ACR is to ground it in real testing, document scope honestly, and maintain it as your product evolves. With the right process (and tools like Corpowid for auditing and monitoring), your VPAT becomes a reliable asset instead of a last-minute scramble.
Section 508 compliance helps ensure digital services are accessible to people with disabilities—especially for U.S. federal agencies and vendors. This guide explains requirements, WCAG alignment, and practical steps to meet and maintain compliance.
