Learning should be easier to reach.

We aim to make this website usable with keyboards, screen readers and mobile devices. We use WCAG 2.2 Level AA as a design and testing target; this is not a certification of complete conformance.

Controls that help

• Skip links and visible keyboard focus.
• Text labels, structured headings and SVG controls.
• Optional silent 3D scene playback, a pause control and a still image when reduced motion is requested.
• Form labels and error messages that keep your entered information available for correction.
