+= Accessibility Statement for Kibana
+++++
+<titleabbrev>Accessibility</titleabbrev>
+++++
+
+Elastic is committed to ensuring digital accessibility for people with disabilities. We are continually improving the user experience, and strive toward ensuring our tools are usable by everyone.
+
+[float]
+[[accessibility-measures]]
+== Measures to support accessibility
+Elastic takes the following measures to ensure accessibility of Kibana:
+
+* Maintains and incorporates an https://elastic.github.io/eui/[accessible component library].
+* Provides continual accessibility training for our staff.
+* Employs a third-party audit.
+
+[float]
+[[accessibility-conformance-status]]
+== Conformance status
+Kibana aims to meet https://www.w3.org/WAI/WCAG21/quickref/?currentsidebar=%23col_customize&levels=aaa&technologies=server%2Csmil%2Cflash%2Csl[WCAG 2.1 level AA] compliance. Currently, we can only claim to partially conform, meaning we do not fully meet all of the success criteria. However, we do try to take a broader view of accessibility, and go above and beyond the legal and regulatory standards to provide a good experience for all of our users.
+
+[float]
+[[accessibility-feedback]]
+== Feedback
+We welcome your feedback on the accessibility of Kibana. Please let us know if you encounter accessibility barriers on Kibana by either emailing us at accessibility@elastic.co or opening https://github.com/elastic/kibana/issues/new?labels=Project%3AAccessibility&template=Accessibility.md&title=%28Accessibility%29[an issue on GitHub].
+
+[float]
+[[accessibility-specs]]
+== Technical specifications
+Accessibility of Kibana relies on the following technologies to work with your web browser and any assistive technologies or plugins installed on your computer:
+
+* HTML
+* CSS
+* JavaScript
+* WAI-ARIA
+
+[float]
+[[accessibility-limitations-and-alternatives]]
+== Limitations and alternatives
+Despite our best efforts to ensure accessibility of Kibana, there are some limitations. Please https://github.com/elastic/kibana/issues/new?labels=Project%3AAccessibility&template=Accessibility.md&title=%28Accessibility%29[open an issue on GitHub] if you observe an issue not in this list.
+
+Known limitations are in the following areas:
+
+* *Charts*: We have a clear plan for the first steps of making charts accessible. We’ve opened this https://github.com/elastic/elastic-charts/issues/300[Charts accessibility ticket on GitHub] for tracking our progress.
+* *Maps*: Maps might pose difficulties to users with vision disabilities. We welcome your input on making our maps accessible. Go to the https://github.com/elastic/kibana/issues/57271[Maps accessibility ticket on GitHub] to join the discussion and view our plans.
+* *Tables*: Although generally accessible and marked-up as standard HTML tables with column headers, tables rarely make use of row headers and have poor captions. You will see incremental improvements as various applications adopt a new accessible component.
+* *Color contrast*: Modern Kibana interfaces generally do not have color contrast issues. However, older code might fall below the recommended contrast levels. As we continue to update our code, this issue will phase out naturally.
+
+To see individual tickets, view our https://github.com/elastic/kibana/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3AProject%3AAccessibility[GitHub issues with label "`Project:Accessibility`"].
+
+[float]
+[[accessibility-approach]]
+== Assessment approach
+Elastic assesses the accessibility of Kibana with the following approaches:
+
+* *Self-evaluation*: Our employees are familiar with accessibility standards and review new designs and implemented features to confirm that they are accessible.
+* *External evaluation*: We engage external contractors to help us conduct an independent assessment and generate a formal VPAT. Please email accessibility@elastic.co if you’d like a copy.
+* *Automated evaluation*: We are starting to run https://www.deque.com/axe/[axe] on every page. See our current progress in the https://github.com/elastic/kibana/issues/51456[automated testing GitHub issue].
+
+Manual testing largely focuses on screen reader support and is done on:
+
+* VoiceOver on MacOS with Safari, Chrome and Edge
+* NVDA on Windows with Chrome and Firefox
