WAI-ARIA 1.1 Accessibility Check Updates
By Sean Needham
Updating to WAI-ARIA 1.1
The World Wide Web Consortium (W3C) recently made Accessible Rich Internet Applications Suite (WAI-ARIA) 1.1 an official recommendation. The update of WAI-ARIA from 1.0 to 1.1 introduces new ways of making web content accessible to users of assistive technologies.
Siteimprove has updated the following Accessibility checks to account for the update of WAI-ARIA to 1.1:
- “Invalid WAI-ARIA role, state or property” (under success criterion 4.1.2 Name, Role, Value)
- “Missing required states or properties” (under success criterion 4.1.2 Name, Role, Value)
This update will only impact your check results if you have been using the new WAI-ARIA 1.1 features. Then your Accessibility Score might improve since we now recognize more WAI-ARIA 1.1 features as correct code.
If you are using some of the WAI-ARIA features from WAI-ARIA 1.0, your Accessibility Score should stay the same, since no WAI-ARIA 1.0 features were deprecated in WAI-ARIA 1.1.
If you are not using WAI-ARIA at all, your Accessibility Score should stay the same. Please note that there are many other ways to make web content accessible than by using WAI-ARIA features, so not using WAI-ARIA doesn't necessarily mean bad accessibility.

Improving the way we set focus during Accessibility testing
Siteimprove has also done an improvement to the way we set focus on page elements during our testing. This change has been made to improve the accuracy of our testing for a particular subset of customer websites.
The following Siteimprove Accessibility checks might be affected by the recent change in how we set focus during testing:
- “Color contrast is insufficient” (under success criterion 1.4.3 Contrast (Minimum))
- “Color contrast is insufficient” (under success criterion 1.4.6 Contrast (Enhanced))
- “No option to skip repeated content” (under success criterion 2.4.1 Bypass Blocks)
- “Element not highlighted on focus” (under success criterion 2.4.7 Focus Visible)
In some cases, your Accessibility Score may change due to improved accuracy in these checks.
