RNIB Tried and Tested certification (previously " RNIB Approved") relates only to the accessibility and usability of the product, website or app as assessed using the RNIB criteria set out below:
We assess against WCAG 2.0 AA standards and also include an assessment with high contrast schemes, as this affects a number of partially sighted people. An assistive technology assessment is then carried out using screen reader and magnification programmes to identify usability issues.
We carry out an assessment against RNIB’s internal app accessibility and usability guidelines. We use the speech and magnification software available on iOS and Android phones using recent or the latest operating systems.
We carry out an assessment against RNIB’s internal inclusive design guidelines, which cover visual, tactile and audio aspects of the user interface. We use simulation devices such as apps and items from the Inclusive Design Toolkit
developed by Cambridge University, as well as the knowledge we have gained from observing blind and partially sighted people use products through our user testing.
For all areas, we carry out observed user testing once the issues raised in the expert assessment have been addressed. Observed user testing is always carried out with a minimum of 10 blind and partially sighted people.
RNIB uses its best endeavours during the testing to ensure accessibility and usability, but we make no comment on the content or general use of products, websites or apps beyond testing the product against the criteria set out above. Our aim is to assist blind and partially sighted people to identify when a product or service is accessible and usable and enable them to make an informed choice. We bear no liability for any use of the website, app or product or any information contained therein.
