Severity

How badly a barrier affects people, from stopping a task entirely to a minor inconvenience, used to order fixes.

Severity is the rating an evaluation gives each barrier to say how much it matters. A common scale has three or four levels: critical, where a group of people cannot complete the task at all, such as a checkout that does not work by keyboard; serious, where the task is possible but very difficult; moderate, where it is slower or confusing; and minor, where the standard is missed but the effect is small.

Severity decides the order of remediation, and it is separate from WCAG level: a Level A failure can be minor in one place and critical in another. A report that gives severity alongside the criterion, the location, and the fix lets a team plan the work instead of reading a flat list.

Remediation
Fixing the barriers an evaluation found, usually in order of how badly each one blocks people.
Accessibility evaluation
A structured review of how a website or app does against WCAG, done by people using assistive technology, not only a scan.
Success criterion
One testable requirement in WCAG, with a number, a level, and a plain statement of what must be true.
