What are the Web Content Accessibility Guidelines (WCAG)?

WCAG is a set of measurable standards for web accessibility, developed by the World Wide Web Consortium (W3C). There are three conformance levels (A, AA, AAA).

Boise State WCAG Conformance

Boise State complies with WCAG Conformance Level AA per University Policy 8140.

These standards ensure web content works for users whether they are using a computer with a keyboard and mouse, a mobile phone, or if they are using assistive technology like screen readers, alternative keyboards, braille readers, voice-to-text input, or screen magnification.

WCAG Standards

WCAG 2.x is built around four standards: perceivable, operable, understandable, and robust.

1. Perceivable

Users read and interact with websites in different ways, often using assistive technology. This standard provides measurable ways to improve your website so users and assistive technology alike can understand the content presented using their senses including sight, sound, and touch.

2. Operable

Users should be able to use all the functions of your website regardless of whether they use a keyboard and mouse or another type of assistive technology.

3. Understandable

Understandable sites have clear, simple instructions, explain complex issues in plain language, and avoid unusual, inconsistent, or unexpected functions.

4. Robust

Robust sites follow recognized standards and conventions for the web.
