BIK BITV-Test — Germany's Disability-Organisation-Developed Web Accessibility Test Run by 20 Test Centres

The BIK BITV-Test is a manual accessibility-testing methodology based on the German BITV regulation and, through it, WCAG. Its origin is three research projects (2002–2018) funded by the Federal Ministry of Labour and Social Affairs under the BIK label; the original test was developed together with the associations for blind and visually impaired people DBSV and DVBS, and later with self-help organisations, web agencies and experts. Since 2018 it has been further developed by DIAS GmbH and is operated by a network of 20 qualified test centres: agencies and independent experts, self-help organisations, university centres and examiners with disabilities. BIK describes it as the established procedure since 2005 for comprehensive and reliable testing, with 98 test steps in the current version, and in November 2024 an extended BIK BITV-Test + WCAG 2.2 was added. Earlier descriptions report 52 checkpoints scored to a maximum of 100 points, with over 90 points labelled accessible.
The strength of the model is human, expert testing with disabled examiners, and a stable method over two decades. The weaknesses: the sources provide no statistics on test volumes, pass rates or improvements achieved by tested sites, the test is a paid service, and checkpoint counts differ between descriptions as the method has evolved. It is therefore a well-established process rather than a proven-impact intervention.
