Accessibility Audits, Testing, and VPAT

Explore how accessibility audits, assistive-technology testing, and VPATs work together to evaluate digital experiences, document conformance, and align with WCAG, ADA, Section 508, and global standards.

Why accessibility audits, testing, and VPATs are critical

Automated testing can surface code-level issues, but it can’t show whether people with disabilities can actually complete tasks or navigate your digital experiences independently. Meaningful accessibility requires structured audits, assistive-technology testing, and clear documentation through VPATs and ACRs, ensuring teams understand real barriers, verify conformance, and build confidence with internal and external stakeholders.

Key disciplines for evaluating and documenting digital accessibility

Explore the essential components of accessibility auditing, from structured evaluations to assistive-technology testing and conformance documentation, and understand how organizations verify and communicate digital accessibility with confidence.

Accessibility audits and methodologies

Learn how audits identify accessibility barriers by evaluating websites, applications, and digital content against standards like WCAG, ADA, Section 508, and EN 301 549. This includes approaches for scoping, sampling, issue categorization, and building repeatable workflows.

Accessibility Audits, Testing, & VPAT frequently asked questions

What’s the difference between an accessibility audit and accessibility testing?

An accessibility audit is a structured, criteria-based evaluation of digital content against standards such as WCAG or Section 508. Accessibility testing focuses on how people actually interact with the experience—often including assistive-technology testing, usability checks, and user-flow validation. Most organizations use both to understand conformance and real-world usability.

AT-informed testing means evaluating digital experiences with real assistive technologies such as screen readers, magnifiers, and voice input tools. It reveals barriers that automated tools and visual reviews cannot catch. For example, unexpected reading order, missing states, or focus issues that affect navigation.

Automated tests are useful for quickly flagging common issues like missing alt text or incorrect HTML structure. However, they typically detect only 20–30% of WCAG criteria. They serve as a starting point—not a replacement—for manual review, AT testing, and user-journey evaluation.

A VPAT is considered credible when it is accurate, complete, and based on verified testing, rather than assumptions or automation alone. Clear explanations of methodologies, supported assistive technologies, and the exact WCAG or Section 508 criteria evaluated help buyers trust the documentation.

Most organizations update VPATs annually or whenever significant new features, components, or redesigns are released. Procurement teams expect VPATs to reflect current functionality, not legacy versions, so regular updates support transparency and compliance.

Depending on the organization, audits may include websites, mobile apps, PDFs and documents, forms, e-commerce flows, dashboards, maps, media, and interactive components. Many teams also audit third-party integrations or embedded systems to ensure they meet internal accessibility requirements.

Shift-left means moving accessibility checks earlier in design and development. Instead of discovering issues at the end of a project, teams evaluate wireframes, prototypes, components, and early builds—reducing remediation costs and preventing issues from recurring across releases.
