Built so that everyone in the room can use it.

Our target

The public website and the sign-in flow are built to the Web Content Accessibility Guidelines (WCAG) version 2.2 at Level AA. We measure every public page against that standard at desktop and phone widths with an automated check on every release, and we walk a manual list once per release: the keyboard alone through the header, the search, the phone menu, every form and the footer; one heading of the first level and a sensible outline on every page; named landmarks; a text alternative for every image; link text that says where it goes; labelled fields with errors that are announced and name the field; the page at 200 percent text size and at 320 pixels wide with no sideways scroll; contrast; motion; target size; and the title of every page.

No organisation certifies WCAG conformance itself. When the public pages pass our own checks in full, we will commission an independent audit and publish its report here.

What we do

• Keyboard. Everything on the public pages, in the search and in the phone menu can be reached and used with a keyboard, and nothing traps the focus. A skip link at the top of every page jumps to the content.
• Visible focus. The element with keyboard focus shows a two pixel ring in ink, set two pixels off the element, on the paper and on every colour block.
• Contrast. Text is at least 4.5:1 against its background and large text and the edges of controls at least 3:1, in the light and the dark theme. The logo orange is used for one word in a headline, for rules and for colour blocks, never for small text on the paper and never with white text on it.
• Reduced motion. When your device asks for reduced motion, sections do not rise or fade, the header does not animate, the search opens without a transition and the scroll story on the home page shows every step as a plain stacked page.
• Captions and transcripts. Every lesson video has captions and a transcript.
• Text resize. The pages are laid out in relative units, so text can be enlarged to 200 percent and the page reflows at 320 pixels wide without sideways scrolling.
• Structure. Every page has one heading of the first level, headings in order, named landmarks for the header, the navigation, the content and the footer, and a title that names the page. The language of the page is declared.
• In a game. A teacher can set learning settings for a student that apply wherever the student plays: extra time, captions, read aloud, large print and a calm display.

The signed-in dashboard

The dashboards for teachers, students and families, the quiz studio, the office suite and the tools for the projector are not yet reviewed against WCAG 2.2 in full. They share the same paper and ink, the same focus ring and the same muted text colours as the public pages, and they carry a Readability panel with a dyslexia-friendly font, larger text, more spacing and a calmer display. We are working through them screen by screen and will extend this statement to them as each is reviewed.

Known limitations

• The drawing tools for the projector (graph paper and the map and diagram annotator) are pointer tools. There is no way to draw with the keyboard alone, though every control around the drawing surface can be reached with it.
• A printable worksheet is a page layout for paper. The same sheet opens on a screen from the QR code in its footer, and that screen view is the one we treat as the accessible form.
• Payment is taken on a page hosted by Stripe, which follows Stripe's own accessibility statement rather than this one.
• The signed-in screens listed above are still being reviewed, and some controls in them do not yet meet the standard.
