DHS Trusted Tester Process & Certification Program

DHS Trusted Tester Process & Certification Program

The DHS Trusted Tester Process is a manual test approach that aligns with the ICT Testing Baseline, and provides repeatable and reliable conformance test results. DHS offers training and formal accessibility testing certification for using the DHS Trusted Tester Process. Agencies that adopt the Trusted Tester Process only accept test results from individuals who have been certified as Trusted Testers.

Note that DHS no longer provides training and certification on Trusted Tester v4.0.

Email the Department of Homeland Security (DHS) Accessibility Helpdesk at accessibility@hq.dhs.gov with questions regarding the Trusted Tester Process & Certification Program.
