Independent Accessibility Assurance

Independent Accessibility Validation

Accessibility claims should be supported by evidence. 508 Audit independently evaluates websites, software, digital documents, remediation work, and accessibility documentation against the requirements that apply to the engagement. We help government buyers, prime contractors, and technology vendors determine whether accessibility work is actually ready to procure, accept, publish, or deliver.

Use cases

Where independent validation fits

Evaluate vendor accessibility claims before award.

Review an ACR, VPAT, product demonstration, or accessibility response and perform targeted testing where additional evidence is needed.

Verify digital deliverables before the work is accepted.

Test completed websites, applications, documents, or other ICT against the accessibility requirements established for the engagement.

Confirm that accessibility findings are actually closed.

Retest corrected issues and document whether remediation resolved the original accessibility barriers without introducing new ones.

Independently evaluate automated accessibility output.

Determine what the technology corrected, what it missed, where human judgment is still required, and whether the finished result satisfies the agreed acceptance criteria.

Scope

What 508 Audit can validate

Scope is defined per engagement. Not every engagement includes every type of testing.

  • Websites and web applications
  • Software and SaaS products
  • PDFs and digital documents
  • Accessibility remediation work
  • VPATs and Accessibility Conformance Reports
  • Vendor accessibility claims
  • Automated document-remediation output
  • Accessibility deliverables produced by subcontractors or implementation partners

How it works

Evidence before acceptance.

  1. 01
    Scope

    Identify the applicable standard, contractual requirement, deliverable, and acceptance criteria.

  2. 02
    Test

    Perform the manual, assistive-technology, document-specific, and automated testing appropriate to the scope.

  3. 03
    Compare

    Compare actual results against the vendor claim, remediation report, ACR, or required accessibility criteria.

  4. 04
    Document

    Provide evidence-backed findings identifying what passed, what remains unresolved, and what requires additional remediation.

  5. 05
    Verify

    Where requested, retest corrected findings before final acceptance.

Automation

When software performs the remediation, the software should not be the only judge of the result.

Automation can reduce accessibility production effort, especially across large document inventories. It does not eliminate the need for human judgment around complex structure, tables, forms, reading order, meaningful alternative text, OCR quality, and other context-dependent accessibility requirements.

508 Audit can evaluate representative output from an automated remediation workflow, identify remaining issue classes, and measure the qualified human effort still required before final delivery.

This service can support government agencies evaluating a platform, prime contractors managing a remediation workstream, or technology vendors seeking an independent accessibility review of their output.

Independence

Independent does not mean disconnected.

508 Audit can work alongside an agency, prime contractor, remediation provider, software vendor, or implementation team while maintaining a clearly defined validation role.

The purpose is not to create another layer of paperwork. It is to give the buyer or delivery team evidence that the accessibility claim matches the delivered result.

Standards

Validation against the requirements that apply to the engagement.

The applicable standard depends on the buyer, technology, jurisdiction, and contract.

Federal Section 508 engagements may be mapped to the Revised Section 508 Standards and their incorporated WCAG requirements.

ADA Title II web and mobile engagements are evaluated against WCAG 2.1 Level AA where the rule applies.

Document engagements may include PDF/UA and applicable WCAG or Section 508 requirements.

WCAG 2.2 or other standards can be included where required by contract, organizational policy, or project scope.

Who this is for

Built for public-sector delivery.

Government Agencies

Prime Contractors

An accessibility QA function for proposal commitments and post-award delivery.

Technology Vendors

Independent testing and documentation supporting public-sector accessibility claims.

Accessibility and Remediation Technology Providers

Human validation of automated or AI-assisted accessibility output.
