CPACC - Certified Professional in Accessibility Core Competencies Disability Types and Barriers Questions and Answers

Question 1

A user with a motor disability who cannot use a mouse relies on keyboard-only navigation. Which of the following website features would present the MOST significant barrier to this user?

Accepted Answer

A drag-and-drop interface for uploading files.

Answer

A drag-and-drop interface requires precise pointer control, which is a significant barrier for keyboard-only users and those with motor disabilities who cannot operate a mouse. The other options present barriers to users with different disability types (visual, auditory, and cognitive, respectively) but do not directly impact keyboard navigation for a user with a motor disability.

Question 2

Which theoretical model of disability views disability as a societal construct, created by environmental, attitudinal, and organizational barriers?

Accepted Answer

The Social Model

Answer

The Social Model of disability posits that disability is caused by the way society is organized, rather than by a person's impairment. It focuses on removing barriers that restrict life choices for people with disabilities. The Medical Model views disability as a problem of the person to be fixed, the Charity Model sees people with disabilities as objects of pity, and the Functional Solutions Model focuses on practical ways to overcome limitations.

Question 3

A student with dyslexia is reviewing an online textbook for a class. Which of the following would likely be a barrier to their comprehension?

Accepted Answer

Long passages of justified text with no images or headings.

Answer

Long, unbroken blocks of justified text can create a 'river of white' effect that makes it difficult for individuals with dyslexia to track lines of text. Justification can also cause inconsistent spacing between words, further hindering readability. The other options are generally considered accessibility best practices that would likely help, not hinder, the student.

Question 4

An individual who is Deaf or hard of hearing is MOST likely to encounter a significant accessibility barrier with which of the following?

Accepted Answer

A podcast that is published without an accompanying transcript.

Answer

For individuals who are Deaf or hard of hearing, audio content without a text-based alternative like a transcript or captions is inaccessible. While the other options are valid accessibility barriers, they primarily affect users with cognitive, visual, and motor or cognitive disabilities, respectively.

Question 5

The Web Content Accessibility Guidelines (WCAG) are organized around four main principles. Which principle states that users must be able to operate the interface and that it cannot require an interaction that a user cannot perform?

Accepted Answer

Operable

Answer

The 'Operable' principle of WCAG ensures that users can interact with all user interface components and navigation. This includes making all functionality available from a keyboard, as some users cannot operate a mouse.
