Accessibility Statement

RAWeb partial compliance declaration

This declaration applies to the uni.lu website (www.uni.lu).

Compliance status

The Web Content Accessibility Guidelines (WCAG) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. This website is partially conformant with WCAG 2.1 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.

This website is partially compliant with the European Standard EN 301 549 and the Web Accessibility Assessment Framework (RAWeb) version 1.1 as a result of the non-conformities listed below.

Additional notes

Validity of the generated source code

The generated source code of the site pages is not fully valid according to the specified document type. However, for the reasons mentioned below, the RAWeb criterion 8.2 corresponding to this point has been marked as compliant.

Officially, WCAG criterion 4.1.1 relating to this RAWeb criterion 8.2 has been removed from WCAG 2.2 and must be considered as still satisfied with regard to WCAG 2.1, as well as the European standard EN 301 549.

In practice, this criterion no longer has any benefit for accessibility for people with disabilities. Any accessibility problems arising from the invalidity of the generated source code are covered by other RAWeb criteria.

Unaudited third-party elements

Video player

The “YouTube” video player was not fully audited during the process.

However, it has been checked that its presence does not have an impact on either use or consultation of the website.
