DHS Trusted Tester certification is the most credible way to verify that an auditor actually knows how to evaluate a digital asset against WCAG. At Accessible.org, nearly all of our auditors hold the DHS Trusted Tester certification — and every audit report undergoes a quality assurance process where a DHS Trusted Tester reviews the report and a professional who is blind or visually impaired spot checks.
What Is DHS Trusted Tester Certification?
The DHS Trusted Tester certification is a manual accessibility evaluation credential developed by the Department of Homeland Security. It requires 40 to 80 hours of coursework followed by a certification exam that requires a score of 85% to pass. This is not a weekend workshop and exam.
The Trusted Tester process is a standardized, code-inspection-based approach to evaluating web content for conformance with Section 508 standards, which align with WCAG. Every certified Trusted Tester has demonstrated that they can apply evaluation methodologies in practice, not just answer questions about them on a multiple choice exam. The Trusted Tester demonstrates applied skill. It shows you have solid proficiency.
Passing the DHS Trusted Tester exam doesn’t automatically mean someone is an excellent auditor, but it’s a really good sign. And what many people don’t realize is the DHS Trusted Tester exam is a better indicator of auditing ability than any IAAP certification.
Why Does Accessible.org Prioritize Trusted Tester Certification?
Because as more people enter the accessibility space, the gap between who claims to be an expert and who actually is one keeps growing. We are extremely selective about our auditors. Every auditor must have genuine audit experience, a longstanding interest in accessibility, and demonstrable expertise before we even consider them.
The Trusted Tester certification tracks with what we already require. It confirms that an auditor can produce consistent, reliable conformance test results. When a client hires Accessible.org for a WCAG 2.1 AA audit, their digital asset is being evaluated by someone whose skills have been formally verified through one of the most respected accessibility credentials available.
Our audits are fully manual. Every evaluation involves screen reader testing with NVDA, JAWS, and/or VoiceOver, keyboard testing, visual inspection, code inspection, browser zoom testing, and color contrast analysis. We only use an AXE automated scan as a secondary check.
What Role Does a Native Screen Reader User Play in the QA Process?
Our audit team includes professional who are blind and use a screen reader as their primary means of navigating digital content. These professionals serve as an additional QA filter on our audit reports.
There is a meaningful difference between an auditor who is proficient with a screen reader and someone who depends on one. A sighted auditor can test with NVDA or JAWS and identify WCAG conformance issues. A native screen reader user experiences the digital asset the way an end user with a visual disability would. They catch things a sighted auditor might technically flag but not fully appreciate in terms of real-world impact.
This is not user testing. User testing is experiential and time-limited. This is a deliberate QA layer built into our audit workflow. The native screen reader user reviews audit findings to confirm that our reports are accurate and that nothing has been missed.
What Does This Mean for Your Audit?
It means your audit report has been through multiple layers of review before it ever reaches you. The auditor who conducts the evaluation is a trained, certified professional. The report is then reviewed through our QA process, which includes assessment by someone who lives and works with assistive technology every day.
When you receive your audit report, you can track every issue with confidence that it reflects a genuine accessibility barrier. Every finding includes the issue description, location, applicable WCAG success criterion, remediation recommendations, and visual documentation. Once your team begins remediation, Accessibility Tracker makes tracking your progress and managing validation straightforward.
The quality of an accessibility audit comes down to who is doing the work. A scan cannot replace a manual audit. And not every auditor brings the same level of rigor. DHS Trusted Tester certified auditors along with spot check user testing is how Accessible.org audits consistently deliver reports organizations can rely on for WCAG 2.1 AA conformance, ADA obligations, and European Accessibility Act (EAA) readiness.
