What Are VPAT Versions?

VPATs are regularly updated to reflect changes in accessibility regulations and technological advancements. Each version aligns with the latest accessibility requirements to ensure that organizations provide accurate compliance documentation.

The major VPAT versions include:
VPAT 2.0 introduced a structured format for evaluating the accessibility of digital products. This version laid the foundation for standardized accessibility reporting.
VPAT 2.1 expanded upon this by incorporating the Revised Section 508 guidelines, making it essential for organizations working with U.S. federal agencies.
VPAT 2.2 added support for WCAG 2.1 criteria, broadening its scope to reflect updated digital accessibility practices.
VPAT 2.3 and later versions continued refining accessibility documentation, with VPAT 2.4 and 2.5 aligning with WCAG 2.2, improving the accuracy of conformance reporting.
Selecting the correct VPAT version ensures compliance with the most relevant standards, minimizing legal risks and improving accessibility.

VPAT 2.0 vs. 2.1 vs. 2.2 vs. 2.4

Understanding the differences between VPAT versions helps businesses choose the most applicable one for their needs.
VPAT 2.0 established a structured approach to documenting accessibility compliance. However, as regulations evolved, VPAT 2.1 became necessary for companies working with government agencies, as it incorporated Revised Section 508 standards. VPAT 2.2 went further, adding WCAG 2.1 requirements, which made it more relevant for businesses focused on web accessibility.
With the release of VPAT 2.4 and 2.5, accessibility reporting has improved significantly, ensuring compliance with WCAG 2.2. Organizations should always use the latest version to stay aligned with current laws and procurement requirements.

What is an ACR (Accessibility Conformance Report)?

An Accessibility Conformance Report (ACR) is the completed version of a VPAT. It provides a structured, detailed summary of accessibility conformance, helping businesses communicate their compliance levels clearly to buyers, regulatory bodies, and procurement teams.
An ACR includes a breakdown of WCAG and Section 508 compliance, highlighting both fully compliant and partially compliant elements. It also provides an assessment of accessibility barriers and outlines recommended remediation steps. This transparency ensures that organizations accurately represent their digital products` accessibility status.
Unlike a VPAT template, which is a blank form, an ACR is a fully completed document that details how a product meets accessibility requirements. This is a crucial step for organizations seeking government contracts or enterprise partnerships.

Why Do VPAT Versions & ACRs Matter?

Choosing the correct VPAT version and completing an ACR ensures businesses remain compliant with accessibility regulations. An outdated VPAT may not meet current legal standards, leading to contract rejections, accessibility complaints, or legal consequences.
By updating to the latest VPAT version and ensuring an accurate ACR, businesses can:
  • Increase procurement eligibility for government contracts.
  • Avoid compliance risks associated with outdated accessibility documentation.
  • Improve accessibility for users, ensuring digital inclusion.
In an era of increasing digital accessibility enforcement, businesses must stay ahead of regulatory changes. Regularly reviewing and updating VPAT documentation not only helps with compliance but also enhances user experience and inclusivity.
