Designed for more people
We aim for a clear, usable learning experience across devices and ways of navigating. The site includes semantic landmarks, visible keyboard focus, labeled forms, keyboard-operable navigation and accordions, and support for reduced motion.
Accessibility is ongoing
WCAG 2.2 AA is our accessibility target. This early experience has not been independently audited, and we do not claim certification. Educational media, captions, transcripts, and accessible learning resources will require review before lessons are published.
Tell us what gets in the way
