 Accessibility targets
 ---------------------
 
-We want to make Wagtail accessible for users of a wide variety of assistive technologies. The specific standard we aim for is `WCAG2.1 <https://www.w3.org/TR/WCAG21/>`_, AA level. Wagtail’s administration user interface isn’t accessible at the moment (see `issue #4199 <https://github.com/wagtail/wagtail/issues/4199>`_), but here are specific assistive technologies we aim to test for, and ultimately support:

 We aim for Wagtail to work in those environments. Our development standards ensure that the site is usable with other assistive technologies. In practice, testing with assistive technology can be a daunting task that requires specialised training – here are tools we rely on to help identify accessibility issues, to use during development and code reviews:

+Known accessibility issues

+Wagtail’s administration interface isn’t fully accessible at the moment. We actively work on fixing issues both as part of ongoing maintenance and bigger overhauls. To learn about known issues, check out:
+
+* The `WCAG2.1 AA for CMS admin <https://github.com/wagtail/wagtail/projects/5>`_ issues backlog.
+* Our `2021 accessibility audit <https://docs.google.com/spreadsheets/d/1l7tnpEyJiC5BWE_JX0XCkknyrjxYA5T2aee5JgPnmi4/edit>`_.
+
+The audit also states which parts of Wagtail have and haven’t been tested, how issues affect WCAG 2.1 compliance, and the likely impact on users.
