WACA certification
With this certificate, the WACA initiative strives for a very high level and outstanding quality of accessibility, which is why the most basic WCAG criteria must be met for successful certification. The auditors test according to a predefined scheme and their own testing methodology strictly according to these criteria. The WACA certificate is awarded at 3 different levels. For each WCAG success criterion, a separate grading for gold, silver and bronze has been defined. This means that websites that do not meet the highest WCAG requirements or are best practice, but have basic accessibility and do not exclude anyone from using the website, can also be awarded. For the Silver or Bronze grades, accessibility efforts must be clearly and unambiguously recognizable, see definition of WACA grades.
WACA certifies websites that can be narrowed down precisely, usually defined by a URL, and draws a representative sample (test sample) from this. However, the following content or functions of a website are generally excluded from the audit:
- PDF
- EPUB
- Live transmitted time-based media
- Content that is only available to a closed group of people and not to the general public (extranets and intranets).
- external content from third-party providers that was neither financed nor developed by the website operator and is therefore not subject to its control (such as Google Maps, YouTube, Facebook, external iframes and widgets, etc.), defined as follows:
- Third-party content that cannot be interacted with (e.g. Facebook tracking pixels) is excluded from the check.
- Third-party content that does not provide basic, central functionality of the page is excluded from the check.
- Third-party content that provides additional information and is essential for users requires an alternative.
- If a website consists largely of third-party content, certification is rejected and the order is not accepted. Website is not auditable in this case.
- Online maps and map services, but these must have an accessible alternative.
- Google Captcha (ReCaptcha V2): Only valid for WACA quality levels Silver and Bronze.
General Comment of the Certification Authority:
The tested sample has a very strong orientation towards accessibility. The international website zeroproject.org , the Austrian website austria.zeroproject.org and the subdomain scaling-solutions.zeroproject.org largely comply with the international web content accessibility guidelines WCAG 2.2 A and WCAG 2.2 AA, which means that a WACA Silver certificate can be awarded.
Conferencing tools for the Zero Project Conference, such as the agenda spreadsheet and the embedded YouTube conference livestream, were not included in the scope of the audit, as these tools are only online for the annual conference and are therefore not a permanent part of the website.
