Questions about common definitions
In this section, you'll be asked questions about common accessibility terms and definitions. Be sure to review these before your interview so that you can provide clear and concise answers.
What is accessibility?
Accessibility refers to the ability of everyone, regardless of their physical or mental abilities, to access and use a space or service.
In the built environment, this means ensuring that buildings and public spaces can be accessed and used by everyone, regardless of their level of mobility. This can include things like adding ramps and Braille signage, as well as providing adequate lighting and acoustics.
When it comes to services, accessibility means making sure that everyone can use them, regardless of any barriers they may face. This can include everything from providing alternative formats for materials to offering training for staff on how to best serve customers with disabilities. By increasing accessibility, we can make our spaces and services more inclusive for everyone.
From a web point of view, it includes things like making sure that websites can be used by people who are blind or have low vision, and that web content can be read aloud by screen readers.
What is accessibility testing?
Accessibility testing is the process of assessing how well a software application accommodates users with disabilities. This can include hearing impairments, visual impairments, physical disabilities, and cognitive disabilities.
The goal of accessibility testing is to identify any barriers that may prevent users with disabilities from using the software. This can involve testing the user interface, menus, buttons, and other controls to ensure that they are easy to use. In addition, accessibility testing may also involve assessing the color contrast of text and visuals, as well as the clarity of audio playback.
By identifying and addressing any accessibility issues early on, developers can ensure that their software is usable by the widest possible audience.

What are the four principles of accessibility?
When it comes to accessibility, there are four key principles to keep in mind: perceivable, operable, understandable, and robust.
First and foremost, information and user interface elements must be perceivable - that is, they must be visible or audible.
Next, they must be operable - that is, users must be able to interact with them using their preferred input method.
In addition, the information and user interface elements must be understandable - that is, they must be clear and easy to use.
Finally, the information and user interface elements must be robust - that is, they must be compatible with assistive technologies and future-proofed against changes in technology.
By keeping these four principles in mind, you can ensure that your site or application is accessible to all users.
What is WAI-ARIA?
WAI-ARIA is a technology that can be used to add extra information about the structure and function of a page. This can be especially helpful for users with disabilities who are using assistive technologies.
WAI-ARIA is supported by most modern web browsers, and you can use it to add information such as labels, descriptions, and keyboard shortcuts.
When using WAI-ARIA, you should keep in mind that it is a supplemental technology. This means that it should be used in addition to other accessibility features, such as providing text alternatives for non-text content.
Questions about the Web Content Accessibility Guidelines
In this section, you will be asked questions about the Web Content Accessibility Guidelines (WCAG). These are a set of international standards that dictate how to make web content accessible to everyone, regardless of any disabilities they may have.
What is the WCAG?
The Web Content Accessibility Guidelines (WCAG) are a set of standards for making web content accessible to people with disabilities. The WCAG is developed by the World Wide Web Consortium (W3C), an international standards body.
There are three levels of conformance: A, AA, and AAA. The WCAG 2.0 standards are currently the most widely-used guidelines for accessible web design.
The WCAG 2.1 standards were released in June 2018 and are rapidly gaining popularity. The WCAG standards include a wide range of accessibility features, from providing alt text for images to designing pages that can be navigated using only a keyboard.
By following the WCAG standards, web designers can help ensure that their content is accessible to everyone.
What is the difference between WCAG 1.0 and 2.0?
WCAG 1.0 was published in 1999 and WCAG 2.0 in 2008. Both guidelines are developed by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C).
The biggest difference is that WCAG 1.0 contains 14 guidelines organized under four principles (perceivable, operable, understandable, and robust), while WCAG 2.0 has twelve guidelines divided into three levels of conformance (A, AA, and AAA).
Another important distinction is that WCAG 1.0 uses technologies such as HTML and CSS, while WCAG 2.0 uses newer technologies such as WAI-ARIA and SVG. In addition, WCAG 2.0 provides more detailed guidance on how to create accessible content.
Finally, WCAG 1.0 is technology-specific while WCAG 2.0 is technology-neutral. This means that WCAG 1.0 only applies to web content delivered using HTML, while WCAG 2.0 can be applied to any type of web content, including web applications and rich media.
Questions about methods and how-to
In this section, you will be asked questions about various methods and how-to information.
What is the most important thing to keep in mind when making a website accessible?
There are many things to keep in mind when making a website accessible, but one of the most important is to ensure that all content is perceivable. This means that users must be able to see or hear the information on the page.
To make sure your content is perceivable, you can provide text alternatives for non-text content, such as images or videos. You can also use color and contrast to make sure your content is visible, and choose fonts that are easy to read.
In addition, you should ensure that all user interface elements are operable. This means that users must be able to interact with the page using their preferred input method.
Finally, you should make sure that the information and user interface elements are understandable and robust. This means that they must be clear and easy to use, and compatible with assistive technologies. By keeping these four principles in mind, you can help ensure that your website is accessible to all users.
What are some methods for making web content accessible?
There are many methods for making web content accessible. Some of the most common include providing text alternatives for non-text content, using color and contrast to improve visibility, choosing fonts that are easy to read, and designing pages that can be navigated using only a keyboard.
In addition, you can use WAI-ARIA to add extra information about the structure and function of your page. This can be especially helpful for users with disabilities who are using assistive technologies.
Finally, you should test your website regularly to ensure that it is accessible to all users.
How can you test a website for color blindness?
There are a few different ways that you can test a website for color blindness.
One way is to use the Color Contrast Checker tool, which is available for free online. This tool lets you enter the URL of the website you want to test, and it will then generate a report that shows how well the site meets the contrast requirements for people with different types of color vision deficiency.
Another way to test a website for color blindness is to use a browser plugin like NoCoffee Vision Simulator. This plugin allows you to simulate what the site would look like to someone with a specific type of color vision deficiency, which can be very helpful in finding potential accessibility issues.
Finally, it's always a good idea to ask someone with color vision impairment to test the site for you, as they may be able to notice problems that you wouldn't otherwise catch.
How can you test a website for hearing impairments?
While most website accessibility testing tools focus on visual impairments, it is also important to test for hearing impairments.
There are a few key ways to do this.
First, you can use a screen reader to test how well the website can be read aloud. This will help to identify any areas where text is not being properly read or where audio descriptions are missing.
Additionally, you can test the website's audio quality and volume levels to ensure that they are sufficient for users with hearing impairments.
Finally, you can also test for captioning accuracy and completeness. By testing for all of these factors, you can ensure that your website is accessible to everyone.
How can you test a website for low vision?
There are a few different ways that you can test a website for low vision.
One method is to use a screen reader, which will read the text on the screen aloud. This can be helpful for people who have difficulty reading small print. Another method is to increase the font size or the contrast on the screen. This can make it easier to read text that is otherwise difficult to see.
Finally, you can also use a magnifier to enlarge the entire page or selected elements on the page. By testing a website in these different ways, you can ensure that it is accessible to people with low vision.
How can you test a website for motor impairments?
There are a number of ways to test a website for motor impairments.
One method is to use a screen reader, which will read out the text on the website as well as provide information about the structure of the page.
Another method is to use a keyboard navigation tool, which will allow you to move around the website without using a mouse.
Finally, you can also use a magnifier tool to enlarge the text and images on the website.
By testing the website with these different tools, you can ensure that it is accessible for users with motor impairments.
How can you test a website for seizures?
There are a few different ways to test your website for seizures. First, you can use an online tool like the Seizure Risk Analysis Tool (SRAT). This tool will help you identify which areas of your site are most likely to trigger seizures.
You can also use a seizure simulator, which is a program that mimics the effects of a seizure.
Finally, you can ask someone with epilepsy to test your site. If you know someone with epilepsy, they can help you identify areas of your site that may be more likely to trigger a seizure.
By testing your website for seizures, you can help to ensure that your site is accessible to everyone.
What is the difference between an accessibility audit and an accessibility test?
There are two main types of evaluations that can be performed to assess the accessibility of a digital product: an accessibility audit and an accessibility test.
An accessibility audit is a broad overview of the product's compliance with accessibility standards. It typically includes a review of the code, design, and content to identify any potential barriers that could prevent users with disabilities from using the product.
An accessibility test, on the other hand, is a hands-on assessment of how well a user with a disability can perform specific tasks using the product. This type of evaluation is often used to assess the effectiveness of specific accessibility features, such as alternative text for images or captioning for videos.
While both audits and tests are important for ensuring the accessibility of digital products, they serve different purposes and should be used as complementary tools in an overall accessibility program.
Questions about accessibility coding and web standards
In this section, you will be asked questions about accessibility coding and web standards.
What is the difference between alt text and longdesc?
Alt text and longdesc are two ways of adding descriptions to images on the web.
Alt text is a brief description that is displayed in place of an image if the image cannot be loaded.
Longdesc is a longer description that can be accessed by clicking on a link or icon.
Both alt text and longdesc can be used to provide information about the content of an image, but alt text is generally shorter and more concise. Longdesc can provide a more complete description, making it useful for images that are complex or have a lot of detail.
In addition, longdesc can be used to provide information about the function of an image, whereas alt text is primarily used to describe the visual content. When choosing between alt text and longdesc, consider how much information you need to provide and how much space you have available.
If you only need to provide a brief description, then alt text may be sufficient. However, if you need to provide more detailed information, then longdesc may be a better option.
What is the difference between a site map and an accessibility map?
A site map is a representation of all the content on a website, typically organized in a hierarchical fashion. It can be used to help visitors find what they're looking for, as well as to give search engines an overview of the site's structure.
An accessibility map, on the other hand, is a map that shows which parts of a website are accessible to people with disabilities. This can be important for both compliances with disability laws and for making sure that everyone can use and enjoy the site.
While both types of maps can be helpful, they serve different purposes and should not be confused.
Questions about accessibility software and hardware
In this section, you will be asked questions about accessibility software and hardware.
What is the difference between a screen reader and a text-to-speech program?
A screen-reader is a software program that assists blind or visually-impaired users by reading aloud the text that is displayed on the computer screen.
A text-to-speech program, on the other hand, is a software application that converts written text into spoken words.
Both screen-readers and text-to-speech programs can be used to improve accessibility for individuals with vision impairments, but they differ in terms of functionality and features.
Screen-readers are specifically designed to work with computer applications and websites, while text-to-speech programs can be used to convert any written text into speech. Screen-readers also typically offer a wider range of features than text-to-speech programs, such as the ability to navigate websites and control the cursor without using a mouse.
Ultimately, the choice of which type of program to use depends on the individual's needs and preferences.
What is the most popular screen reader?
A screen reader is a software program that converts on-screen text into speech, making it possible for blind and visually impaired users to access digital information.
There are a number of different screen readers available on the market, but the most popular one is JAWS (Job Access With Speech). Developed by Freedom Scientific, JAWS is available for both Windows and macOS. As well as reading on-screen text aloud, JAWS also provides various commands for navigating web pages and applications. It can be used with a variety of assistive technologies, such as Braille displays and refreshable Braille displays.
While JAWS is the most popular screen reader, there are a number of other options available, including NVDA (NonVisual Desktop Access), Window-Eyes, VoiceOver (built into MacOS) and Orca (built into Linux).
What is the most popular text-to-speech program?
In recent years, text-to-speech (TTS) programs have become increasingly popular. TTS programs allow users to input text and convert it into speech, making it easy to create audio versions of documents or to listen to books and other reading materials.
There are a variety of TTS programs available on the market, but the most popular is undoubtedly Natural Reader. Natural Reader offers a high-quality TTS engine that can convert text into natural-sounding speech in a variety of languages. In addition, it offers a wide range of customization options, allowing users to adjust the speed, pitch, and volume of the generated speech. Natural Reader also has a convenient mobile app, making it easy to listen to text on the go.
For all these reasons, Natural Reader is the clear choice for the most popular TTS program.
What is the difference between assistive technology and adaptive technology?
When most people think of assistive technology, they picture devices like wheelchairs and walkers. However, assistive technology can actually refer to any type of device or software that helps people with disabilities to perform everyday tasks. This can include anything from dishwashers with special controls for people with limited mobility to text-to-speech software that helps people with visual impairments to read.
In contrast, adaptive technology is specifically designed to be used by people with disabilities. This includes modified computer keyboards, adapted door handles, and other devices that help people with physical limitations to live independently. While adaptive technology is a subset of assistive technology, the two terms are often used interchangeably.
What is the most popular assistive technology?
Assistive technology is any type of technology that helps people with disabilities to achieve their goals. There are a wide variety of assistive devices available, ranging from simple tools like magnifying glasses to sophisticated computer software.
The most popular type of assistive technology is communication aids. These devices can help people with speech impairments to communicate more effectively.
Other popular types of assistive technology include mobility aids, educational aids, and environmental control systems.
Questions about disabilities
What is the most common form of color blindness and how can you make your website accessible to people with this disability?
The most common form of color blindness is red-green color blindness, which affects approximately 8 percent of men and 0.5 percent of women. People with this condition have trouble distinguishing between red and green, and may also have difficulty with other colors in the green-yellow-red spectrum.
While there is no cure for color blindness, there are a number of ways to make websites more accessible to people with this condition. For example, using high contrast color schemes can help to make text more readable, and avoiding the use of color as the sole means of conveying information can help to ensure that important information is not missed.
By taking these simple steps, website owners can help to ensure that their site is accessible to the widest possible audience.
What is the most common form of hearing impairment and how can you make your website accessible to people with this disability?
Hearing impairments are fairly common, affecting approximately 15% of the world’s population. The most common form of hearing impairment is called sensorineural hearing loss, which is caused by damage to the inner ear or the auditory nerve. This type of hearing loss can be caused by exposure to loud noise, viral infections, head trauma, and certain diseases.
While there is no cure for sensorineural hearing loss, it can be managed with the use of Hearing Aids or cochlear implants. To make your website accessible to people with this disability, you can provide text-to-speech options and captioning for videos. You can also use high-contrast color schemes and large font sizes to make your site easier to read.
By taking these simple steps, you can help to ensure that everyone has equal access to your content.
What is the most common form of low vision and how can you make your website accessible to people with this disability?
Most forms of low vision are caused by degenerative diseases such as macular degeneration, glaucoma, and diabetic retinopathy. These diseases damage the retina, the light-sensitive tissue at the back of the eye, causing people to lose central vision. As a result, people with low vision often have difficulty reading and navigating their surroundings.
Fortunately, there are a number of ways to make your website accessible to people with low vision. Text can be enlarged or displayed in high-contrast colors to make it easier to read.
Audio descriptions can be used to provide information about images, and navigation can be streamlined to reduce the need for precise visual cues.
By taking these steps, you can help make your website more accessible to people with low vision.
What is the most common form of seizure and how can you make your website accessible to people with this disability?
A seizure is a sudden, uncontrolled electrical disturbance in the brain. Seizures can cause a variety of symptoms, from convulsions and loss of consciousness to more subtle changes in behavior. The most common form of seizure is called a tonic-clonic seizure, also known as a grand mal seizure. This type of seizure is characterized by muscle rigidity, loss of consciousness, and convulsions. Seizures can be caused by a variety of factors, including head injuries, stroke, infectious diseases, and certain neurological conditions. Approximately 1 in 26 people will experience a seizure at some point in their lives.
There are a few things you can do to make your website accessible to people with seizures. First, avoid using flashing lights or animation. These can trigger seizures in some people. Second, provide alternative content for any audio or video content on your site. This will allow people to still access the information even if they cannot see or hear the original content. Finally, make sure your website can be navigated using keyboard commands. This will allow people with limited mobility to still use your site.
By following these simple guidelines, you can help to ensure that your website is accessible to everyone.
How can you make a website accessible to people with cognitive impairments?
When designing a website, it is important to consider the needs of all users, including those with cognitive impairments. There are a number of steps you can take to make your site more accessible to this group.
First, use clear and concise language. This will help to ensure that your content can be easily understood.
Second, use visual cues to help guide users through your site. For example, you can use color to highlight important links or buttons.
Third, provide options for users to control their experience. For instance, allow visitors to adjust the font size or contrast levels on your site.
By taking these steps, you can help to improve the accessibility of your website for everyone.
While there are certainly other questions that could be asked in an interview for a position in accessibility testing, these thirty should give you a good starting point.
