Assessment results
An assessment is a comprehensive process that measures compliance with WCAG 2.2 Level AA success criteria. The assessment process includes 24 tests, and each test covers one or more accessibility requirements.
There are 3 types of requirement:
- automated - identifies instances and evaluates them automatically
