Questions: Digital Accessibility Basics

Question 1

A web developer adds descriptive alt text to all images, uses proper H1/H2/H3 heading tags, and ensures color contrast meets WCAG thresholds. Which users benefit from these changes?

• A. Only users who are permanently blind or have severe visual impairments
• B. Only users who have explicitly enabled accessibility mode in their browser settings
• C. Screen reader users, people with low vision, search engines, sighted users who are skimming, and anyone with temporary or situational impairments
• D. Only users who specifically requested an accessible version of the site

Answer: (C)

Accessible design benefits a much broader population than just people with permanent disabilities. Alt text helps screen reader users AND search engines indexing images. Heading structure helps screen reader users navigate AND sighted users scanning a page. Good contrast helps users with low vision AND anyone viewing a screen in bright sunlight. Accessible content is better-structured content — it works better for everyone, which is the key mental model shift the topic calls for.

Question 2

An accessibility auditor runs an automated checking tool on a website and receives a report showing zero violations. The auditor should conclude that...

• A. The site is fully accessible and requires no further review
• B. The automated tool caught all accessibility issues since it checked every element
• C. The automated tool found no detectable violations, but manual testing with assistive technology is still required, since automated tools typically catch only 30-40% of accessibility problems
• D. The site meets WCAG compliance and can be certified as accessible

Answer: (C)

Automated accessibility checkers are useful but limited — they typically catch only 30-40% of real accessibility issues. They can verify that alt text is present, but not whether it is meaningful. They can check color contrast ratios but not whether the page structure makes sense when read aloud by a screen reader. Nuanced issues like confusing navigation order, unhelpful link text ('click here'), and missing form labels often require manual testing with actual assistive technology to discover.

Question 3

Digital accessibility primarily benefits people with permanent disabilities like blindness or deafness, and provides no meaningful value to other users.

• T. True
• F. False

Answer: False

This is the most common accessibility misconception. Accessibility benefits people with temporary impairments (broken arm, eye surgery recovery), situational impairments (noisy room, bright sunlight, one hand occupied), aging-related changes, and people using small screens or slow internet. Captions help people in noisy environments. High contrast helps people outdoors. Alt text helps search engines. The estimated 1-in-4 adults with some disability is just the starting point — accessible design reaches far beyond that.

Question 4

Using the built-in heading styles (H1, H2, H3) in a word processor or web editor, rather than just making text visually large and bold, improves accessibility for screen reader users.

• T. True
• F. False

Answer: True

Screen readers allow users to navigate a document by jumping from heading to heading — but only if those headings are marked with actual semantic heading tags, not just styled text. Text that looks like a heading visually but is coded as ordinary paragraph text with large bold formatting appears to a screen reader as one undifferentiated block, with no navigational structure. Proper heading tags give the page a skeleton that both screen readers and search engines can traverse.

Question 5

Why is 'accessibility is a feature I add for a small audience' the wrong mental model for digital accessibility? What is the better mental model, and what evidence supports it?

Model answer: The better mental model is: accessible content is better-structured, more clearly written content that works better for everyone. Evidence: roughly 1 in 4 adults has some disability, but accessibility also benefits people with temporary injuries, situational impairments (bright sunlight, noisy rooms), aging-related changes, and slow internet. Practices that help screen reader users — clear headings, meaningful link text, alt text — also help sighted users scanning, search engines indexing, and anyone with a slow connection that blocks images from loading.

Framing accessibility as a 'niche add-on' leads to it being deprioritized or skipped. Framing it as 'good structure that benefits all users' integrates it into normal content creation. The same practices that let a blind user navigate a document also make it easier to skim, search, and reuse. This reframe is what makes accessible design sustainable — it is not extra work for a small audience, it is quality work for everyone.
