TU Wien makes every effort to make our website accessible in accordance with the Web Accessibility Act ("Web-Zugänglichkeits-Gesetz" - WZG).

This declaration on accessibility applies to websites of TU Wien, which are hosted on a TU.it server and are connected to the central TUW TYPO3 system.

Efforts to support accessibility

TU Wien takes the following measures to ensure accessibility:

  • Accessibility is part of our internal guidelines.
  • Continuous training on accessibility is offered for our employees.
  • Formal methods for quality assurance of accessibility exist within the company.
  • We include people with disabilities in the development of the accessibility of the website.

Compliance status

This website ist compliant with conformance level AA of the "Web Content Accessibility Guidelines - WCAG 2.1". It was awarded the silver quality seal.

Known accessibility issues

Unfortunately, we still cannot completely exclude one or the other barrier. Please contact us if you notice a problem. 

We are aware of the following recommendations for further improvement of our website:


  • Time-based media: Time-based media is not accessible in all cases because sufficient audio-descriptive alternatives may not be provided.
  • On the "Events" page, the contrast of the gray values is sufficient and WCAG-compliant, but especially on mobile, the information about time and place is written very small and gray and thus not optimally readable.
  • Forms: For submit errors, the form does not scroll up, requiring users to scroll up manually. A darker gray is recommended for the margins of input fields.
  • In the document overview, the links to the documents are only distinguished from the body text by color.


  • Not best practice: on the "Events" page in mobile view, the calendar is visually in front, but after the events in tab order.
  • When searching for events multiple times with the help of a screen reader, the focus is no longer placed at the top of the page.


Unfortunately, not all documents on our website are accessible yet.
