Site accessibility

We have designed the website to be accessible to all visitors to the website and, at the same time, to make their experience as positive as possible through the possibility of customisation. We designed accessibility in accordance with the Accessibility of Websites and Mobile Applications Act on the basis of a self-assessment.

Level of accessibility

The NVQ website is written in HTML5 and uses CSS3 cascading style sheets to design webpages. The jQuery JavaScript library is used for interactions and certain functionalities. The operation and appearance of webpages has been verified in all popular older and newer browsers as well as on different devices and operating systems.

The website is designed to be accessible and user-friendly to all visitors. It has been produced following the AA and AAA level guidelines for the accessibility of online content according to the WCAG 2.1 standard (Web Content Accessibility Guidelines (WCAG) 2.1). Webpages are AA mid-level compliant and upgraded with some AAA high-level requirements that further enhance the user experience for people with limitations.

For webpage compatibility with supporting technologies and accessibility with accessories such as screen readers, the website follows the WAI-ARIA (Web Accessibility Initiative – Assistive Rich Internet Applications) specification guidelines. The HTML code of webpages thus includes descriptions and attributes with additional information for dedicated applications or readers. Examples are alternative texts for graphic elements, input and button labels, etc.

Additional help in the form of hints on input fields, buttons, and links is aimed at less skilled web users.

Accessibility features

Part of the site is a special tool that provides additional website accessibility features. It appears when clicking on the accessibility icon in the lower right corner. The user is provided with:

  • easier navigation with keys on the keyboard;
  • a larger mouse pointer, in white or black;
  • a contrast enhancement of colours;
  • a colour display in greyscale;
  • a white on black dark mode;
  • a standard font suitable for people with dyslexia;
  • a larger font size; thickened font;
  • highlighted links; titles in capital letters.

Visitors can also use keyboard shortcuts:

  • display accessibility options (Ctrl + U);
  • display map of web pages (Ctrl + Alt + K);
  • jump to main content (Ctrl + Alt + V);
  • display subpages with contacts (Ctrl + Alt + S);
  • return to home page (Ctrl + Alt + D).

Possible improvements

The website uses JavaScript scripting language for normal operation, better overall user experience, and greater security. Without proper browser support, navigation is difficult, and it is not possible to display and send web forms in pop-ups.

In the event that CSS style sheets are not supported by your browser, all information can still be accessed, but some content may be duplicated or redundant. The code of webpages contains additional texts intended for display on screens of different sizes or after certain actions.

Independence from JavaScript and CSS sheets would mean a major change in the design and operation of the website.

Many of the WCAG and WAI-ARIA guidelines for improving website accessibility can be interpreted subjectively. Interpretations can also change over time.


We want to make our website as user-friendly as possible. In case of problems accessing any content or information on this site, or if you have feedback or suggestions for improvements, please contact us.
