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.
What the scores represent
CWAC can only detect some accessibility issues. Manual testing is still needed to properly assess accessibility.
CWAC uses an open-source accessibility test suite designed to avoid false positives. However, false positives can sometimes occur, for example if there is a defect in one of the tests.
As such, CWAC scores should be used as an indicator only and not as a measure of accessibility or WCAG conformance.
CWAC scores show how well agencies are using automated accessibility testing on their websites.
A digitally mature agency that regularly uses automated testing and fixes issues as they happen can expect a low CWAC score. An agency that does not use automated testing regularly to find and fix issues early can expect a high CWAC score.
