Interagency Trusted Tester Program

ICT Testing Baseline

Baseline tests attempt to reduce ambiguity, increase consistency of results, and emphasize the methods and techniques that can reliably meet federal accessibility requirements.

The draft ICT Testing Baseline describes how to evaluate conformance to the Revised 508 Standards, which align with WCAG 2.0 Level A and AA Success Criteria. It is organized by categories to help you easily identify applicable requirements. Note that the Baseline is not a test process and does not include testing tools; rather, it should be used to create an accessibility test process. This version is a DRAFT, and has yet to be approved for use.

Email the Department of Homeland Security (DHS) Accessibility Helpdesk at Accessibility@HQ.DHS.GOV with questions.

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.

Trusted Tester v4.0

Note that DHS no longer provides training and certification on Trusted Tester v4.0. Training and a new certification exam for Trusted Tester Version 5.0 are planned to launch in spring 2019.
