About the English version of the BITV-Test web site

The domain bitvtest.eu provides an overview of the BIK projects and the BITV-Test, as well as selected English articles.

BIK are German projects. The current BIK project is called BIK für Alle (BIK for all). The BITV-Test, our articles and tests have all been written in German.

The English site bitvtest.eu does not provide a full translation of all this content. Instead, it offers a general overview of the BITV-Test as a tool for evaluating the accessibility of web sites.

In 2017, a version of the BITV-Test will be released as WCAG-Test.

This site hosts our occasional English articles and publications, and tracks BIK's involvement with other initiatives in the European context.
