The BITV-Test has been used extensively to test the accessibility of many federal administration websites as well as that of many other information-oriented sites
The overview of the BITV-Test outlines the legal background of the BITV-Test and describes its purpose, scope and reliability.
The individual BITV test steps (in German) can be found on the German website. There, you also find a detailed description of the BITV test procedure (in German).
There are three different flavours of BITV-Test:
The final BITV-Test offers a definitive assessment of the accessibility of completed websites. Focusing on a selected sample of pages (the procedure follows WCAG EM), the test provides an accessibility snapshot. It does not cover the intelligibility and usability of content—or only to the extent that usability aspects are reflected in WCAG Success Crtieria on level AA. Apart from these restrictions, a site that passes the test can claim BITV and WCAG conformance: it is deemed accessible for most visitors. The final BITV test is carried out by two trained experta who first test the same page sample independently and then go through an arbitration phase to determine a consensual test result. This result then receives an additional quality assurance by another trained expert with QA status.
The design support test uses the same BITV-Test procedure for checking the accessibility of websites under development, indicating deficiencies that design should remedy. It also provides a rough orientation regarding the degree of BITV conformance. The design support test is carried out by one trained expert and receives an additional quality assurance by another trained expert with QA status. The reliability of test results is limited, the test is meant for internal use only and results shopuld not be published as proof of conformance (or degree of non-conformance).
The BITV self-assessment is a web-based tool for web developers who want to stick to the requirements of the BITV-Test developed by BIK. A questionnaire with test steps allows users to assess the accessibility of the website tested.
