Accessibility Statement

Last updated: 19 June 2026

We want Erudia to be usable by everyone, including people who rely on assistive technology. We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.1, Level AA, and we test against it regularly.

What we've done

The interface is operable by keyboard, with a visible focus indicator and a "skip to content" link.
Controls and form fields have accessible names and ARIA labels for screen readers; dialogs trap focus and return it correctly.
Text and interface colors meet the WCAG AA contrast ratio.
The app respects your operating-system "reduce motion" setting and avoids unnecessary animation.
Pages use semantic headings and landmarks so screen-reader users can navigate by structure.

Known limitations

Some lessons use interactive, visual math tools (for example, dragging a vector or sweeping an angle) that are inherently visual and may be harder to use with a screen reader. We provide text-based questions covering the same material and are continuing to improve keyboard and screen-reader support for these tools.

Tell us about a problem

If you hit an accessibility barrier on Erudia, please email erudia@erudia.org with the page and what happened. We take these seriously and will work with you to fix the issue and give you the information you need in an accessible way.
