Only certain parts of the Trusted Tester program are invited simultaneously to a specific test of a product or service. Most products and services are not publicly advertised and even your invitation to participate in an emailed test is confidential. You may not participate in a test at any time or log out of the program. How do people sign up as trustworthy testers? Customers can register here. We are setting up a Trusted Testn accessibility panel in the UNITED States to give us more feedback on the accessibility of new products. Potential testers go through a screening process to enter the program. Those selected to participate will have the opportunity to try out new Google products in front of the audience and engage directly with Google`s development teams, while providing feedback on accessibility.
