About the English version of the BITV-Test web site

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

BIK is a German project. 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 2011, a version of the BITV-Test will be released as WCAG-Test.

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