Standards We Meet

WCAG 2.1 & Success Criterion

The Web Content Accessibility Guidelines (WCAG) is a guideline which is most commonly used to justify the accessibility of an application, within this guideline are three levels of conformance:

  1. Level A
  2. Level AA
  3. Level AAA

Each level adds further requirements, where level A is the most basic and level AAA is the most advanced; Invotra is expected to provide up to level AA.

The standards are broken up into the following:

  • Principles – perceivable, operable, understandable, robust (POUR).
  • Guidelines – within principles there are guidelines, they provide what is expected as well as how and why.
  • Success criteria – within each guidelines there is success criteria, used in order to validate if we have passed a guideline.
  • Sufficient and advisory techniques – the sufficient techniques being the core and the advisory techniques being suggestions, which may overcome accessibility issues which are not included in the success criteria.
