Success criterion

One testable requirement in WCAG, with a number, a level, and a plain statement of what must be true.

Also called
success criteria

A success criterion is a single testable rule in WCAG. Each has a number, such as 1.1.1, a short name, and a level: A, AA, or AAA. The number gives its place in the structure: the first digit is the principle, the second is the guideline, and the third is the criterion. Together they are the checklist an evaluation works through.

A criterion is written so that a tester can say pass or fail. “Non-text Content” asks whether every image has a text alternative. “Keyboard” asks whether all functionality works from a keyboard. An accessibility report lists the criteria that fail, where, and how to fix them; a VPAT lists how a product does against each one.
