In September, Gebruiker Centraal (User Needs First) centres on Testember, a month filled with activities, concrete examples, and helpful tools. It’s a perfect opportunity to assess the digital accessibility of websites and apps. Here are 6 tools, some in Dutch and some in English, that may help:
- Gebruiker Centraal has compiled a range of digital accessibility tools in Dutch, from colour contrast checks to comprehensive web page audits. Additionally, the English-language section of their website, User Needs First, provides the Service Design Toolkit. This toolkit includes handbooks and tools to support adopting a user-centric approach to designing digital public services.
- The WAVE Web Accessibility Evaluation Tool (English) allows you to check a webpage for common accessibility issues and identify potential problem areas.
- The WCAG Explanation by NL Design System (Dutch) makes accessibility requirements concrete and explains various criteria, including how to test them. Alternatively, WCAG’s own website offers a Quick Reference to WCAG requirements in English.
- The DigiToegankelijk Dashboard (Dutch) displays the accessibility status of websites and apps from government organisations, giving you quick insight into where improvements are needed.
- With the latest version of PAC 2026 (English), you can check PDF files for technical accessibility. The tool includes AI-supported checks, reducing the need for manual testing. If you cannot or prefer not to install software, the PDF Tag Viewer (English) by Toegankelijk Online offers a low-threshold initial check in your browser, without uploading your PDF to the cloud.
- The Accessibility Ladder by DigiToegankelijk (Dutch) provides insight into how your organisation manages digital accessibility through 7 questions. The results highlight areas for improvement. The Accessibility Ladder was based on the Safety Culture Ladder (English).
