Agency leaderboard — CWAC
Participating government agencies ranked by their Centralised Web Accessibility Checker (CWAC) scores.
CWAC monitoring programme
At the end of every quarter, starting , the Government Chief Digital Officer (GCDO) is using CWAC to scan publicly facing government websites for accessibility issues.
CWAC scores — lower is better
CWAC counts the accessibility errors it finds on web pages. Each accessibility error is a failure of the Web Content Accessibility Guidelines (WCAG) 2.2, and a potential barrier to a disabled person. As such, low CWAC scores are better.
WCAG 2.2 — World Wide Web Consortium (W3C)
By combining the scores for all of an agency’s websites, we can get a score for the agency. Refer to the ‘Agency leaderboard’ table below for the latest CWAC scores for agencies taking part in the CWAC monitoring programme.
A score of 0 is the best score, as it means there were no errors detected on any of the agency’s web pages that CWAC tested. A score of 100 means there was at least 1 accessibility error found on every page tested.
Remember that automated accessibility testing tools can only find some WCAG failures. A web page that passes all automated accessibility tests is not necessarily accessible or WCAG-conformant. Assessing accessibility always requires manual testing.
How the scores are calculated
The formula for the CWAC score follows a strict binary method when counting web pages with accessibility failures. If a web page has just 1 failure, the page is counted as failed.
The CWAC score formula is:
- Multiply the number of pages with an axe-core failure by the total number of viewport tests, then subtract the number of pages that passed in only 1 viewport.
- Multiply the total number of pages scanned by the total number of viewport tests.
- Divide the value from step 1 by the value from step 2.
- Multiply by 100 for a more readable score.
