Accessibility Testing Guideline?

?The guidelines are organized under 4 principles?

1.Perceivable??

1.1 Text Alternatives - All non-text content has a text equivalent. ?

1.2 Time-Based Media - Provide alternatives for time-based media. ?

1.3 Adaptable - Create content that can be presented in different ways (for example simpler layout) without losing information or structure.?

1.4 Distinguishable - Make it easier for users to see and hear content including separating foreground from background.?

2.Operable??

2.1 Keyboard Accessible - Make all functionality available from a keyboard.?

2.2 Enough Time - All website users need to be given enough time to read and use the content on the page. This guideline affects video and audio-based media, GIFs, carousel, and user sessions that may time out. ?

2.3 Seizures and Physical Reactions - Do not design content in a way that is known to cause seizures.

2.4 Navigable - Provide ways to help users navigate, find content, and determine where they are.

There are 3 levels of testable success criteria??

1. Level A – Basic accessibility?
2. Level AA – Strong accessibility?
3. Level AAA – Excellent accessibility?
