The Dutch government is committed to providing online information that is user friendly, accessible, well designed and findable. The websites of public authorities need to be easy for the public to find, view and use. To make sure that this happens, central government has adopted the Web Guidelines, which its website managers have to apply.

The Web Guidelines are based on internationally recognized rules concerning accessibility, design and sustainability laid down by the World Wide Web Consortium (W3C). If you apply the Web Guidelines correctly, your website will meet the functional, technical and editorial standards that make it accessible for all types of user. For example, the blind and visually impaired. And users of all types of computer, from outdated PCs to the latest mobile devices.

Web Guidelines: ‘apply or explain’

The Web Guidelines (version 2) appear on the list of obligatory open standards laid down by the Standardisation Forum, which promotes open standards and interoperability in Dutch public authorities. All the open standards listed by the Forum are subject to the ‘apply or explain’ principle. Public authorities must apply these standards in their entirety. Or, if they are justifiably unable to do so, they must clearly explain why.

How does DT&V apply the Web Guidelines?

  • By making the Web Guidelines a fixed part of all aspects of website management, from design and editing to further development.
  • Companies carrying out contracts for public authorities are obliged to apply the Web Guidelines.
  • Our website editors have the knowledge and skills necessary to apply the Web Guidelines appropriately. The manuals to enable them to do so are complete and up to date.

Almost 100% Web Guideline compliant

DT&V complies almost 100% with the Web Guidelines. Parts of the website may not comply. Below we explain why.

Components of this site not fully compliant with the Web Guidelines

This site may not comply 100% with the Web Guidelines with respect to:

PDF files

  • Specifications
    PDF files on
  • Cause
    PDF files are subject to very high requirements by the Web Guidelines. They are supplied to DT&V by various parties, not all of whom have the knowledge necessary for creating PDF files in accordance with the Guidelines. As a result, DT&V cannot guarantee that all PDFs on the website will comply with the Web Guidelines.
  • Result
    DT&V believes it has done enough to remedy non-compliance by offering appropriate alternatives.
  • Alternatives
    As a solution for the problem, DT&V has drawn up a set of minimum requirements for PDF files on the website. In principle, it will strive to publish only PDF files that meet the Web Guidelines in full. But for the time being, it will also accept PDFs that meet the following requirements: the layout must be in PDF/A-1a or PDF/UA-1; the text must be selectable and copyable and the file may not contain any scanned text or images or personal data.
  • Measures
    DT&V imposes strict requirements on new PDF files. They must at least comply with the requirements under ‘Alternatives’.

How does DT&V monitor compliance?

  • The editorial team tests the accessibility of all published content. It also carries out project-based interim checks on the content.
  • Experts monitor the accessibility and design of this website regularly. If they encounter problems, DT&V's web managers try to find long-term solutions.
