Accessibility Resources

Useful places to learn, test, and build accessibility skills.

This library brings together practical resources we trust from accessibility standards organizations, assistive technology makers, and accessibility educators. It is for people with disabilities learning their technology and for teams that want to understand accessibility better.

We will keep adding to this collection as tools and guidance change.

New to screen readers? Start with one screen reader and learn the basic navigation commands before using it for accessibility testing. Screen reader testing is valuable, but it does not replace testing with experienced people with disabilities.

Go beyond a checklist and understand how accessible experiences are built.

Accessible Documents

Remember: an accessibility checker can find some problems, but no automated checker can determine whether a document or website is fully accessible. Manual review and human testing still matter.
