The Web Content Accessibility Guidelines (WCAG) provide guidelines and Success Criteria for each corresponding standard to create inclusive digital environments; particularly so people with disabilities have the broadest possible access to content and services.
- There are three levels of conformance, rated from minimally inclusive to broadly inclusive:
- A - minimum level of conformance and effort
- AA - average conformance and effort
- AAA - broadest conformance and effort
- Unfortunately there's not a one -to-one relationship between each criterion and its corresponding standard
- they are applied across all of the technologies that create the digital accessibility landscape
- the steps to show conformance will vary with each application of the corresponding technology
- this may cause confusion as it allows for interpretation in proving conformance
Best Practice: avoid barriers between your consumers and the corresponding content and technologies. This will naturally meet higher WCAG standards, increase usability (and for web applications and content -- will improve Search Engine Optimization).
