Quick Tip: WCAG Structure and Terminology

The Web Content Accessibility Guidelines have two primary components – the normative materials (meaning the guidelines themselves that only change with each new version – 2.2 will likely be released in the coming months) and supporting materials (voluminous resources and materials to help better understand the normative materials). At the foundation of WCAG are principles – Perceivable, Operable, Understandable, and Robust. Each principles has guidelines – high level goals for better accessibility. Each guidelines has testable success criteria which are used to determine WCAG conformance. Each success criterion is assigned a level – A, AA, or AAA.
