ArcSource is a Trusted Tester

ArcSource Group is excited to announce that several members of our Usability/Accessibility Team have successfully completed the extensive Department of Homeland Security (DHS) Trusted Tester (TT) Certification.

Under Section 508 of the Rehabilitation Act, federal institutions and agencies are required to make their electronic and information technology (including web sites and software) accessible to individuals with disabilities.
The Department of Homeland Security Office of Accessible Systems & Technology (OAST) is committed to the development of the common testing approach for accessibility compliance and conformity, named Trusted Tester (TT).  TT provides a code-inspection based test approach for determining software and website conformance to the Section 508 standards.


A Trusted Tester is a person certified to provide accurate and repeatable Section 508 compliance test results for software and Web applications. A Trusted Tester follows the DHS Section 508 compliance Application Test Process, uses approved test tools, and evaluates software and Web applications for compliance with Section 508 standards. Trusted Testers are those who have taken the DHS Trusted Tester Training Course and passed the Certification Exam.


ArcSource Group’s consulting services can help your organization become Section 508 compliant by making your electronic and information technology accessible to all. We can help your organization mitigate risks and ensure that accessibility is done right by enabling faster adoption of new technologies that address your business goals and requirements.


According to the DHS TT Website, here is a list of benefits.
Benefits of Trusted Tester:

  • Promotes a common understanding of the 508 standards.
  • Unifies the test process, the set of test tools, and test results reporting.
  • Test results can be shared for common applications (i.e. Shared Services, COTS, etc.). 
  • Supports IT (Information Technology) governance by integrating Section 508 into the development and acquisition lifecycle. 
  • Promotes the successful adoption of the changes required to integrate the Trusted Tester Program (TTP) within an agency.
  • Improves ability for developers to reproduce test results which expedite remediation of nonconformance.
