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 individual BITV test steps (in German) can be found on the German web site. 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 web sites. Focusing on a selected sample of pages, the test proviudes an accessibility snapshot. It does not cover the intelligibility and usability of content. Apart from these restrictions it can be claimed that a site that passes the test can claim BITV conformance: it is deemed accessible for most visitors.
The design support test uses the same BITV-Test for checking the accessibility of web sites under development indicating deficiencies that further design should remedy and providing a rough orientation regarding BITV conformance. The reliability of test results is limited, the test is meant for internal use only.
The BITV self-assessment is a web-based tool for web developers who want to stick to the requirements of the BITV-Text developed by BIK. A questionnaire with 52 test steps allows users to assess the accessibility of the web site tested.
Web design companies can use the BITV self-assessment to test a reference site. If this site scores 95 points or better, the company will enter the list of qualified web service providers within the listing 90plus. Entrants have demonstrated their capability of building highly accessible web sites.
