WCAG and BITV

In addition to the international Web Content Accessibility Guidelines (WCAG), Germany has the Barrier-Free Information Technology Ordinance (BITV). The goal of the WCAG and BITV is to create uniformity with regard to accessibility. The WCAG sets the international standard in the European Union for the barrier-free design of Internet offerings. The BITV is the implementation of this standard in Germany.

What are the WCAG requirements?

The WCAG specify the international standard for the accessible design of online offerings in the EU.

The W3C guidelines are not official legal regulations. However, they serve as the basis for many laws.

There are now several versions of the WCAG.

  • WCAG 1.0 (1999) - This focuses on HTML and CSS as the most important standards of the Internet.

  • WCAG 2.0 (2008) - This deals with layouts and interactions and their design.

  • WCAG 2.1 (2018) - This deals with contrast requirements and informative graphical elements, among other things.

  • WCAG 2.2 (expected in August 2023)

What are the BITV requirements?

The BITV (Accessible Information Technology Ordinance) is based on the guidelines of the WCAG. It represents the framework for compliance with WCAG in Germany.

The BITV was enacted in 2002, but at that time it was not yet binding with regard to the web pages of German federal agencies. It was not until the end of 2003 that the BITV became mandatory for websites providing services for persons with disabilities, after it was incorporated into legislation. In this way, the WCAG 1.0 was implemented in Germany.

Different versions of the BITV exist, much like the WCAG. In 2008, BITV 2.0 was introduced, which referenced WCAG 2.0, placing an increased emphasis on the design of layouts and interactions. With an updated version of the BITV 2.0 in 2019, the standards to be taken into account were no longer mentioned directly in the regulation, but reference was made to the standards published in the Official Journal of the European Union(New BITV 2.0 in force).

Accessibility Strengthening Act (BFSG)

The (German) Accessibility Strengthening Act (BFSG) transposed the European Accessibility Directive (Directive (EU) 2019/882 on Accessibility requirements for products and services). The law was promulgated in July 2021 and comes into force on 28. June 2025 in force. For the first time, the law obliges private economic actors to comply with accessibility requirements if their products or services fall within the scope of the law.

A helpful site in connection with accessibility and for comparing WCAG and BITV is BIK for all. BIK stands for "barrier-free information and communication".

The "BIK for All" project was funded by the Federal Ministry of Labor and Social Affairs from 2015 to 2018 to raise awareness of accessible websites and promote compliance with the relevant standards. Numerous educational initiatives were carried out together with partners. The project has also produced many solutions for implementation and a WCAG test, which can also be used to test web pages in accordance with the Web Content Accessibility Guidelines (WCAG).

These sections of the online help are based on both the WCAG and BITV guidelines.

From the WCAG, BITV and Intrexx section, you will find a detailed list of all WCAG guidelines and their relevance and implementation in Intrexx. Parallel to this you will find the BITV guidelines. The WCAG and BITV guidelines do not always correspond one-to-one. If they correspond, they are treated together in the online help. Where there is no equivalent, you will find separate descriptions.
