What are the four core principles of the Web Content Accessibility Guidelines (WCAG), often remembered by the acronym POUR?

Answer: Perceivable, Operable, Understandable, Robust

WCAG is organized around four principles—Perceivable, Operable, Understandable, and Robust (POUR). Each principle groups success criteria that together ensure content is accessible to a wide range of users with disabilities.

According to the social model of disability, what is the primary source of disability?

Answer: Environmental and societal barriers that exclude people with impairments

The social model holds that disability arises from the barriers society creates—physical, attitudinal, and systemic—rather than from a person's impairment itself. Removing those barriers reduces or eliminates the disabling effect.

What minimum color contrast ratio does WCAG 2.1 Level AA require for normal-sized body text against its background?

Answer: 4.5:1

WCAG 2.1 Success Criterion 1.4.3 (Level AA) requires a contrast ratio of at least 4.5:1 for normal text. Large text (18pt or 14pt bold) requires only 3:1 at AA, while 7:1 is the Level AAA threshold for normal text.

Which document, adopted by the United Nations in 2006, is the primary international human rights treaty focused on the rights of persons with disabilities?

Answer: The UN Convention on the Rights of Persons with Disabilities (CRPD)

The UN Convention on the Rights of Persons with Disabilities (CRPD), adopted in 2006, is the first comprehensive human rights treaty of the 21st century. It establishes that persons with disabilities enjoy the same rights and fundamental freedoms as all other persons.

In accessibility, what does the term 'keyboard trap' refer to?

Answer: A situation where a user navigating by keyboard cannot move focus away from a component

A keyboard trap occurs when focus enters a UI component—such as a modal or widget—and the user cannot navigate away using only the keyboard. WCAG 2.1 Success Criterion 2.1.2 (No Keyboard Trap) requires that focus can always be moved away using standard keys.

Which of the following best describes 'captions' as an accessibility feature for video content?

Answer: Synchronized text transcriptions of spoken dialogue and relevant non-speech audio

Captions are synchronized text equivalents that include spoken dialogue AND relevant non-speech sounds (e.g., [door slams], [applause]). They differ from subtitles, which typically only translate speech, and from audio descriptions, which narrate visual information for blind users.
