About this Lab

Accessibility Testing Lab is a hands-on environment for learning and practising accessibility testing.

It separates the Lab into Learning paths for progressive learning, Testing methods for reusable references, Exercises for focused practice, and Testing journeys for realistic scenarios.

What this Lab can and cannot establish

The Lab teaches selected practical accessibility-testing techniques. It does not provide exhaustive coverage of accessibility requirements, user needs, technologies, or testing environments.

Completing a Learning path, Exercise, or Testing journey is not a WCAG conformance assessment. Automated and manual technical checks can provide useful evidence, but they do not replace usability evaluation or involving disabled people in research and testing.

For a real review, define and record its scope and exclusions. Arrange additional specialist testing and testing with disabled people when the product, its users, and the risks require it.

Some Exercise and Testing journey workspaces contain deliberate accessibility problems. They are isolated practice material and are not examples to copy into a production service.
