BITV 2.0 is the central regulation for accessible information technology in Germany. It defines binding requirements to ensure that websites and digital services are accessible to everyone, regardless of individual limitations. For those responsible and those implementing it, BITV 2.0 provides clear guidance on how accessibility can be implemented in practice and systematically.
The regulation is closely linked to international standards such as WCAG 2.1 AA and sits within the context of other legal provisions. Its structure, underlying principles, and testing mechanisms ensure that accessibility under BITV 2.0 can be designed in a transparent and verifiable way. This page provides a structured overview to offer guidance and clarity for implementing accessible web projects.
As the Ordinance on Accessible Information Technology, BITV 2.0 is central to digital accessibility in Germany. Its structure follows a clear system: the regulation is divided into sections that contain the legal requirements, as well as annexes that describe the technical and content requirements in detail. This structure enables those responsible to understand and implement the individual requirements in a targeted manner.
BITV 2.0 focuses on the specific requirements for websites and mobile applications. The sections regulate, among other things, the scope of application, exceptions, and the obligations to publish accessibility statements. The annexes contain the technical standards and success criteria, which closely follow international guidelines such as the WCAG. In this way, BITV 2.0 creates a binding basis for accessible information technology and facilitates the practical implementation of legal requirements.
| Structural element | Content and function |
|---|---|
| Sections (§§) | Legal framework, obligations, and exceptions |
| Annexes | Technical requirements, success criteria, and testing procedures |
| Reference to WCAG | Link to international accessibility standards |
The core principles of BITV 2.0 are geared towards creating comprehensive digital participation. The aim is to remove barriers to accessing digital services and to enable equal use of websites and applications for everyone, especially people with disabilities. The guiding concepts of the regulation focus on perceivability, operability, understandability, and robustness—key principles that promote an inclusive digital environment.
BITV 2.0 is primarily addressed to public bodies and institutions that provide digital services. It differs from other standards and laws such as WCAG or the Act on Equal Opportunities for Persons with Disabilities (BGG) in that it specifies practice-oriented requirements for the German legal context. While international standards serve as the basis, BITV 2.0 places particular emphasis on practical implementability and the targeted promotion of digital inclusion in the national context.

The success criteria of BITV 2.0 closely follow the internationally recognised WCAG 2.1 AA. They define which requirements a website or application must meet to be considered accessible under BITV 2.0. The criteria are divided into different areas covering aspects such as perceivability, operability, understandability, and robustness.
The BITV 2.0 assessment system is based on a transparent testing methodology: each success criterion is tested and evaluated individually. The requirements are weighted according to their relevance and feasibility. Particularly central criteria are given higher priority to ensure that key barriers are addressed in a targeted manner. The test results provide a structured basis for optimising digital services.
| Success criterion | Evaluation aspect |
|---|---|
| Perceivability | Accessible presentation of content, e.g. alternative text for images |
| Operability | Keyboard navigation, sufficient time to interact |
| Understandability | Clarity of language, comprehensible structures |
| Robustness | Correct technical implementation, compatibility with assistive technologies |
| Prioritisation | Key criteria are weighted more heavily; tests follow defined methods |
Testing under BITV 2.0 follows a standardised process consisting of several test steps. First, websites or applications are systematically examined against defined criteria. Both manual checks and supporting testing tools are used to capture technical and content-related aspects. A key element is careful documentation of the test results, ensuring transparent traceability of the assessment.
There are significant differences between a self-assessment and an external audit. In a self-assessment, internal stakeholders carry out the BITV check and document the results, whereas an external audit is conducted by independent specialist bodies. Both approaches rely on structured test steps, but differ in depth, scope of documentation, and the binding nature of the results.
| Testing procedure | Characteristics |
|---|---|
| Self-assessment | Conducted independently by internal teams, use of testing tools, flexible depth of testing, internal documentation |
| External audit | Conducted by independent auditing bodies, binding testing methodology, comprehensive documentation, objective results |
| Testing tools | Support both procedures, automate partial checks, provide technical analyses |
| Documentation | Required for traceability; scope varies depending on the testing procedure |
A structured approach is recommended for the practical implementation of BITV 2.0: First, website operators should conduct an inventory of existing accessibility and integrate BITV 2.0 requirements into their development and editorial processes. Typical measures include adjusting navigation and contrasts, providing alternative texts, and optimizing keyboard accessibility. Tools such as accessibility checkers or screen readers support testing and continuous improvement.
The integration of BITV requirements is most successful when it is incorporated into project planning and implementation from the very beginning. Practical examples show that regular training, the use of checklists, and close cooperation between development, design, and editorial teams lead to sustainable improvements. Compared to other standards such as the international WCAG, the implementation paths for BITV 2.0 are more strongly aligned with legal requirements in Germany.
| Implementation path | Special features of BITV 2.0 vs. other standards |
|---|---|
| Integration into processes | BITV 2.0 requires mandatory integration into German administrative workflows, while WCAG is internationally more open |
| Technical measures | Both rely on alternative texts, contrast adjustment, and keyboard accessibility; BITV 2.0 focuses on national specifications |
| Testing and auditing tools | BITV 2.0 recommends specific testing procedures, while WCAG offers a broader selection of tools |
| Practical examples | BITV 2.0 emphasizes German authorities and public bodies, while WCAG is internationally more diverse |

As a regulation, BITV 2.0 is part of the German regulatory framework for digital accessibility and is closely linked to other laws such as the Act on Equal Opportunities for Persons with Disabilities (BGG) and the Barrier-Free Accessibility Strengthening Act (BFSG). While the BGG defines the fundamental principles of equality and accessibility in the public sector, BITV 2.0 specifies the requirements specifically for digital services. The BFSG extends the scope to certain private economic actors and implements European requirements.
The scope of BITV 2.0 primarily covers federal public bodies and their digital services. Through its link to European directives, particularly the EU Web Accessibility Directive, BITV 2.0 is part of a larger European framework that promotes the harmonization of accessibility requirements in the EU. This ensures that national regulations are aligned with European specifications, without BITV 2.0 offering legal guarantees or liability commitments.
BITV 2.0 differs in several points from related standards such as WCAG, EN 301 549, and the BFSG. While WCAG provides international technical standards for accessibility and EN 301 549 defines specific requirements for information and communication technologies in Europe, BITV 2.0 is specifically tailored to the German legal area. It specifies the implementation of accessibility for public bodies in Germany and takes national peculiarities into account, for example, with regard to administrative practice and language.
For public bodies, BITV 2.0 is binding, while the BFSG focuses on certain private providers and transposes European requirements into national law. Depending on the service and scope, private companies must adhere to either BITV 2.0, the BFSG, or directly to EN 301 549. BITV 2.0 thus remains the central standard for digital accessibility in the public sector in Germany.
| Standard/Directive | Special features compared to BITV 2.0 |
|---|---|
| WCAG | International standard, no national specification, basis for many regulatory frameworks |
| EN 301 549 | European standard for ICT, broader scope, technical details |
| BFSG | German law for private providers, implementation of European requirements, supplements BITV 2.0 |
| BITV 2.0 | Binding for public bodies in Germany, national peculiarities and administrative practice |
In the implementation of BITV 2.0, misunderstandings and errors frequently occur in practice. Typical challenges include unclear delimitation of requirements, underestimating the effort for accessible design, and a lack of knowledge about technical details. Organizational stumbling blocks, such as a lack of coordination between development, editorial, and design teams, also lead to accessibility not being implemented holistically.
In practice, frequent errors appear in areas such as the provision of alternative texts, keyboard accessibility, or color choice. Testing tools are often viewed as the sole solution, even though they cannot replace manual testing. To avoid errors, a continuous testing and improvement process is recommended, incorporating both technical and editorial aspects.
| Challenge/source of error | Guidance for avoidance |
|---|---|
| Missing alternative texts | Careful maintenance of all image descriptions in the CMS |
| Insufficient keyboard accessibility | Perform regular tests with keyboard and screen reader |
| Incorrect color contrasts | Check and adjust color schemes with contrast tools |
| Only automated tests | Plan manual tests as a supplement |
| Lack of team coordination | Early involvement of all stakeholders and clear responsibilities |

BITV 2.0 has continuously evolved over time to meet the increasing requirements for digital accessibility. Originally introduced to specify the requirements of the Act on Equal Opportunities for Persons with Disabilities for digital services, the regulation has been revised several times. Important changes concerned the adaptation to international standards such as WCAG 2.1 AA and the expansion of the scope to mobile applications.
These updates are of great importance for practice, as they bring new requirements and testing criteria. Operators of digital services should keep an eye on future developments, as further adjustments are to be expected—for example, through advancing European harmonization and technological innovations. Regular review and adaptation of existing web projects therefore remains a central component of BITV 2.0 implementation.
| Development step | Significance for practice |
|---|---|
| Introduction of BITV (2002) | First binding specifications for accessible web services in Germany |
| BITV 2.0 (2011) | Modernization, stronger orientation towards international standards |
| Adaptation to WCAG 2.1 AA (2019) | Expansion to mobile applications, new testing criteria |
| Planned future changes | Adaptation to European specifications, consideration of new technologies |
BITV 2.0 applies to digital services provided by federal public bodies, such as websites, mobile applications, intranets, and digital administrative services. It also covers documents made available online, such as PDF forms or digital brochures. Private providers are only affected if they act on behalf of public bodies or must comply with specific legal requirements. Services used purely privately or internally are generally not covered.
BITV 2.0 is the central framework for digital accessibility in Germany and forms the binding basis for public bodies to make their websites, documents, and applications accessible. It specifies international standards and supplements them with national requirements, enabling practical implementation in German web projects.
For those responsible, BITV 2.0 provides clear structures, transparent success criteria, and practical testing procedures. Consistently integrating the requirements into development and operational processes makes a significant contribution to ensuring digital services are accessible to all user groups and to promoting digital participation. Regular updates to reflect new technical and legal developments underscore the regulation’s relevance in everyday digital practice.

BITV 2.0 transposes WCAG 2.1 AA into German law, but includes additional national requirements and specific wording for public bodies. While WCAG is internationally oriented and sets general success criteria, BITV 2.0 regulates in a binding manner how these are to be applied in practice in Germany. For implementation, this means that BITV 2.0-compliant services always also meet WCAG 2.1 AA, but must be supplemented by national requirements.

Under BITV 2.0, a website is considered accessible if it meets all relevant success criteria of the regulation and has passed the prescribed testing and evaluation procedures. Key aspects include perceivability, operability, understandability, and robustness. Accessibility is determined and documented through systematic testing—such as as part of an audit—based on the defined criteria.
You can find official resources on BITV 2.0 on the websites of the Federal Ministry of Labour and Social Affairs and the federal monitoring body for accessibility. Guidance, checklists, and legal information are available there for public bodies. Private providers should check whether the BFSG or other regulations apply to them, as BITV 2.0 is primarily relevant for public bodies. Future developments are regularly published on the platforms mentioned.
For private companies, BITV 2.0 is generally not directly mandatory, but it provides valuable guidance for accessible digital services. Key points of contact such as the federal monitoring body and the Federal Ministry of Labour and Social Affairs provide guidance, tools, and checklists.
