Accessibility
Our accessibility commitment and how to report a barrier.
Our target
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA across the whole site.
What we do
- Every page can be used with a keyboard, with a visible focus indicator and a “Skip to main content” link.
- Text and controls meet AA colour contrast in light and dark modes, and colour is never the only way information is shown (for example, evidence grades always carry a text label).
- Tables have captions and header cells; any chart comes with a text description and a data table.
- The site respects your system’s reduced-motion setting and works when zoomed to 400%.
- We test with automated tools (axe-core and Lighthouse), by keyboard, and with a screen reader before each major release.
Known limitations
- Search needs JavaScript. Without it, you can browse research, the library and topics instead.
- Linked source documents (journal PDFs and publisher pages) are outside our control and may not be accessible.
Report a barrier
If something on the site is hard to use, tell us through the contact page. We aim to reply within 7 days.
