The following information is provided to facilitate the approval of testing tools required by Trusted Tester within any IT environments. The Federal Accessibility Community of Practice Working Group constantly updates this information. You can find the latest web testing methodology in the Trusted Tester 5.1 GitHub repository, updated January 2024. All certified Trusted Testers must use this version, as it includes enhancements and updates to the testing process.
Trusted Tester uses the Accessible Name and Description Inspector (ANDI), developed by the Social Security Administration (SSA).
ANDI Installation
- Visit https://www.ssa.gov/accessibility/andi/help/install.html to install ANDI. This installation connects to the SSA servers and will receive updates automatically. Please note that depending on your browser technology, you may need to clear your cache to enable updated functionality.
- You can access the open-source repository for ANDI at https://github.com/SSAgov/ANDI. Please be aware that due to approval processes, this version may be approximately a week behind the latest development release.
Training version of ANDI
In the past, DHS hosted a “training version” of ANDI to complement the Trusted Tester training course content. However, the course now uses the current version of ANDI from SSA. This is the same version that should be used for production testing.
Color Contrast Analyzer
