What are the four WCAG principles guiding accessible training design?

• A. Visible, Usable, Clear, Secure
• B. Perceivable, Operable, Understandable, Robust
• C. Accessible, Functional, Intuitive, Portable
• D. Usable, Compatible, Memorable, Fast

Answer: (B)

The guiding framework for accessible training design is the four WCAG principles: Perceivable, Operable, Understandable, Robust. Perceivable means information and UI elements must be presented in ways users can perceive—provide text alternatives for images, captions or transcripts for media, sufficient color contrast, and scalable text. Operable means the interface can be used with diverse input methods, including keyboard, with clear navigation, enough time to interact, and avoidance of content that could trigger seizures. Understandable means information and operations are easy to understand and predictable—clear language, consistent navigation, and helpful error messages. Robust means content remains accessible across a range of devices and assistive technologies, and stays compatible with evolving tech by following standards and semantic structure.

That’s why the option with Perceivable, Operable, Understandable, and Robust is the correct match. The other lists use terms that don’t align with WCAG’s four guiding principles and wouldn’t ensure a comprehensive, technology-agnostic approach to accessibility.
