Web Content Accessibility Guidelines
The Web Content Accessibility Guidelines (WCAG) are internationally recognized standards that define how to make web content accessible to people with disabilities.
“A part of a series of web accessibility guidelines published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C), the main international standards organization for the internet. They consist of a set of guidelines for making content accessible, primarily for people with disabilities.”

Real World Example
A government benefits portal is adding an online application form used by people with different devices, abilities, and assistive technologies.
The feature can pass functional tests while still blocking users who rely on keyboard navigation, screen readers, captions, or sufficient color contrast. Web content accessibility guidelines keeps that risk visible.
The tester checks the application path with assistive technology expectations in mind, including labels, focus order, error messages, and completion without a mouse.
The team releases a service that more citizens can actually use because Web content accessibility guidelines is treated as a product quality concern, not a cosmetic review.
