The maximum achievable score is 5 points.

On a normalised scale, the score of the accessibility profile corresponds to 0.7 points. This value is weighted at 50% in the overall assessment.

  • Mobile operability: Usability and full display of content in portrait and landscape format; pointing actions and operability by device movement possible with conventional input methods.
  • Keyboard operability: Interactive elements can only be operated with a keyboard and are highlighted when focused on.
  • Voice control: Controls have an accessible label that corresponds exactly to the visual description/name.
  • Compatibility with user agents: User agents and assistive technologies are informed about changes in the state of the user interface as well as status messages.
  • Assistance with interactions: Interaction with forms; pointer entries can be cancelled or undone.
  • Consistency/predictability: Consistent navigation; context remains when focused in or during input.
  • Semantic structure: Content is labelled with structural elements such as headings, lists and labels that reflect the context of meaning.
  • Comprehensibility: Headings, form labels and link texts are understandable, correct language declaration is used.
  • Display flexibility: The presentation of the content can be adapted to the needs of the users: text size, control over animated elements and media.
  • Contrast and sensory characteristics: Adequate contrasts, no expressions such as ‘in the picture on the right’ or ‘click the red button’; information is not conveyed solely by colour.
  • Non-text content (graphics): Informative graphic elements have useful alternative texts.
  • Multimedia alternatives Multimedia content is compatible with at least one alternative sensory channel.

Key findings

The main headings are correctly marked, but all other headings are only visually recognisable as such and therefore not accessible to technical aids. Similarly, various switches are not marked as such. Likewise, the accordions used have not been implemented correctly: screen reader users are not alerted to the fact that it is an accordion and whether it is expanded or minimised. In the emergency plan form, the keyboard or other input devices cannot be used to control the input fields. In the pensions area, it is not possible to scroll through the articles with the keyboard or other input devices. The keyboard focus is not visible for all elements. Texts cannot always be enlarged sufficiently; in some cases, enlargement leads to overlapping, making the text unreadable. Not all colours have sufficient contrast ratios. For example, the light blue used.
