Accessibility

We want every student to be able to use the site, whatever device or assistive technology they use.

What we do

  • Every page works with a keyboard, with visible focus and a skip link.
  • Maths is typeset with MathJax, which screen readers can read, and every question card has a "Read aloud" button that speaks the question using your browser's built-in voice.
  • Text can be enlarged to 200% without losing content, and pages work on narrow phone screens without sideways scrolling.
  • Colour is never the only signal: statuses always carry words ("Passed", "Not started").

Known limitations

Some diagrams in mark schemes are described in words rather than drawn, and the read-aloud voice depends on the voices installed on your device. Printed worksheets use the same maths typesetting, so they can be enlarged before printing.
