Millions of people with disabilities rely on assistive technologies to navigate websites, applications, and digital content. Among these technologies, screen readers play a vital role in making digital platforms usable for individuals with visual impairments, cognitive disabilities, and other accessibility needs. Despite advancements in web development and design, many digital platforms still fail to accommodate users who depend on screen readers. Without proper accessibility testing, visually impaired users encounter significant barriers that prevent them from accessing information, completing transactions, or even performing basic online interactions. In this blog, we will explore the critical role of screen reader accessibility testing, the consequences of inadequate screen reader support, and the legal mandates that ensure digital inclusivity for all.
What Happens Without a Screen Reader?
For individuals who are blind or visually impaired, accessing digital content without a screen reader can be nearly impossible. Screen readers convert on-screen text, buttons, images, and other elements into speech or braille output, allowing users to navigate and interact with websites and applications. Without this assistive technology:
Navigation Becomes Impossible: Users cannot “see” menus, buttons, or links, making it difficult to move through a website.
Critical Information is Lost: Important content, such as descriptions of images, form labels, and error messages, is inaccessible.
Online Interactions Become Challenging: Tasks like shopping, filling out forms, and accessing services require proper accessibility support.
Without screen reader support, digital exclusion becomes a reality, limiting independence and access to essential services.
How Testers Evaluate Websites Using Screen Readers
Testers play a crucial role in ensuring websites are accessible to individuals with disabilities by using the same screen reader tools that visually impaired users rely on. By testing digital platforms from an accessibility perspective, they identify barriers and ensure compliance with accessibility standards like WCAG, ADA, and Section 508.
Here’s how testers evaluate a website using screen readers:
Text-to-Speech Verification: Testers use screen readers like NVDA, JAWS, and VoiceOver to check if all on-screen text is correctly converted into speech and read in a logical order.
Keyboard Navigation Testing: Since many users rely on keyboard shortcuts instead of a mouse, testers verify that all interactive elements (menus, buttons, links) can be accessed and navigated using keyboard commands.
Form Accessibility Checks: Testers confirm that screen readers correctly read out form labels, input fields, and error messages, allowing users to complete online transactions without confusion.
Image & Alt Text Validation: Using screen readers, testers ensure that images have proper alt text and that decorative images do not interfere with navigation.
By incorporating screen reader testing into their accessibility audits, testers help developers create an inclusive experience where visually impaired users can navigate, interact, and access content effortlessly.
A sample video explains how to perform testing using screen readers.
(In the shared video, we identified a bug related to the list items on the page. There is a single list item enclosed within ‘ul’ and ‘li’ tags, which is unnecessary for the content. This should be changed to a ‘p’ or ‘span’ tag to better suit the structure and purpose of the content.)
List of Screen Reader Tools for Accessibility Testing

Accessibility is crucial in web and app development. As we rely more on digital platforms for communication, shopping, healthcare, and entertainment, it’s important to make sure everyone, including people with disabilities, can easily access and use online content. Accessibility testing helps identify and fix issues, ensuring websites and apps work well for all users, regardless of their abilities. It’s not just about following rules, but about making sure all users have a positive experience. People with disabilities, such as those with vision, hearing, mobility, or cognitive challenges, should be able to navigate websites, find information, make transactions, and enjoy digital content easily. This can include features like text descriptions for images, keyboard shortcuts, video captions, and compatibility with screen readers and assistive devices. Understanding the ADA vs. Section 508 vs. WCAG guidelines helps create accessible experiences for all.
Three key accessibility standards define how digital content should be made accessible:
ADA(Americans with Disabilities Act) is a U.S. civil rights law that applies to private businesses, public places, and online services. It ensures equal access to goods, services, and information for people with disabilities.
Section 508 is specific to U.S. federal government agencies and organizations receiving federal funding. It mandates that all electronic and information technology used by these entities is accessible to individuals with disabilities.
WCAG(Web Content Accessibility Guidelines) is a globally recognized set of standards for digital accessibility. While not a law, it is frequently used as a benchmark for ADA and Section 508 compliance.
Many people find it challenging to distinguish between the Americans with Disabilities Act (ADA) and Section 508 because they are both U.S. laws designed to ensure accessibility for people with disabilities. However, they apply to different entities and serve distinct purposes. The ADA is a civil rights law that applies to private businesses, public places, and online services, ensuring equal access to goods, services, and information for people with disabilities. For instance, an e-commerce website must be accessible to users who rely on screen readers or other assistive technologies.
In contrast, Section 508 targets U.S. federal government agencies and organizations receiving federal funding. Its primary aim is to ensure that all electronic and information technology used by these entities, such as websites and digital documents, is accessible to individuals with disabilities. For example, a government website providing public services must be fully compatible with assistive technologies to ensure accessibility for all users.
Although these standards overlap in their objectives, they differ in their applications, enforcement, and compliance. WCAG (Web Content Accessibility Guidelines) also plays a crucial role as a globally recognized set of standards that guide digital accessibility practices. This guide will delve into these standards at length, providing details of their background, main principles, legal considerations, and best practices in compliance.
ADA: The Legal Backbone of Digital Accessibility in the U.S.
The Americans with Disabilities Act (ADA) is a federal civil rights statute passed in 1990 to ban discrimination against people with disabilities. Although initially aimed at physical locations, courts have come to apply Title III of the ADA to websites, mobile applications, and online services.
Key Titles of the ADA
Title I: Employment discrimination.
Title II: Accessibility for government services and public entities.
Title III: Covers businesses and public accommodations
Legal Precedents & Enforcement
Domino’s Pizza v. Guillermo Robles (2019) – A blind user sued Domino’s because its website was inaccessible via screen readers. The court ruled in favor of accessibility.
Target (2008) – Target paid $6 million after being sued for website inaccessibility.
Beyoncé’s Website Lawsuit (2019) – The singer’s official website faced legal action due to a lack of screen reader compatibility.
Compliance Requirements
The Department of Justice (DOJ) has not specified a technical standard for ADA compliance, but courts frequently reference WCAG 2.1 AA as the benchmark.
Who Must Comply with ADA?
Private businesses offering goods/services to the public.
Example: E-commerce platforms, healthcare providers, financial services, and educational institutions.
Consequences of Non-Compliance
Lawsuits & Legal Fines – Organizations may face costly legal battles.
Reputational Damage – Public backlash and loss of consumer trust.
Forced Compliance Orders – Companies may be required to implement accessibility changes under legal scrutiny.
Section 508: Accessibility for Government Agencies
Section 508 is part of the Rehabilitation Act of 1973, requiring U.S. federal agencies and organizations receiving federal funding to make their digital content accessible.
508 Refresh (2017)

How do I obtain a VPAT template?
The official VPAT templates can be downloaded from the Information Technology Industry Council (ITIC) website. Ensure you select the correct template based on the applicable accessibility standards.
What happens if my product does not fully support accessibility standards?
If your product has accessibility gaps:
Document the issues in the VPAT report Provide explanations and planned improvements Work on accessibility enhancements in future updates to improve compliance
Is a VPAT report legally required?
While a VPAT is not always legally required, it is often necessary for selling digital products to government agencies or large enterprises. Many organizations use it to demonstrate compliance with accessibility laws such as the Americans with Disabilities Act (ADA) and the European Accessibility Act (EAA).
Can I create a VPAT report myself, or should I hire an expert?
You can create a VPAT report in-house if your team has expertise in accessibility compliance. However, for a thorough evaluation, many organizations hire accessibility specialists to conduct audits and complete the VPAT accurately.
How often should a VPAT report be updated?
A VPAT should be updated whenever:
A product undergoes major changes or new versions are released Accessibility features are improved or modified New accessibility standards are introduced or revised
The Americans with Disabilities Act (ADA) establishes standards for accessible design for both digital and non-digital environments in the USA. Being passed in 1990, it doesn’t even specify websites or digital content directly. ADA primarily focuses on places of public accommodation. With the rapid usage of digital technology, websites, mobile apps, and other online spaces have been considered places of public accommodation. Although the ADA doesn’t specify what standards websites or apps should follow, it considers WCAG as the de facto standard. So in this blog, we will be providing you with an ADA website compliance checklist that you can follow to ensure that your website is ADA compliant.
Why is it Important?
Organizations must comply with ADA regulations to avoid penalties and ensure accessibility for all users. For example, let’s say you own a pizza store. You have to ensure that the proper accessible entry points can allow people in wheelchairs to enter and eventually place the order. Similarly, for websites, a person with disabilities must also be able to access the website and place the order successfully. The reason why we chose the example of a pizza store is because Domino’s was sued for this very same reason as their website and mobile app were not compatible with screen readers.
What is WCAG?
The Web Content Accessibility Guidelines (WCAG) is the universal standard followed to ensure digital accessibility. There are three different compliance levels under WCAG: A (basic), AA (intermediate), and AAA (advanced).
A is a minimal level that only covers basic fixes that prevent major barriers for people with disabilities. This level doesn’t ensure accessibility but only ensures the website is not unusable.
AA is the most widely accepted standard as it would resolve most of the major issues faced by people with disabilities. It is the level of compliance required by many countries’ accessibility laws (including the ADA in the U.S.).
AAA is the most advanced level of accessibility and is targetted only by specialized websites where accessibility is the main focus as the checks are often impractical for all content.
Based on WCAG standard 2.1, these are some of the checklists that need to be followed in the website design. To ensure you can understand it clearly, we have broken down the ADA website compliance checklist based on the segments of the websites. For example, Headings, Landmarks, Page Structure, Multimedia content, Color, and so on.
A well-structured webpage improves accessibility by ensuring that content is logically arranged and easy to navigate. Proper use of headings, spacing, labels, and tables helps all users, including those using assistive technologies, to understand and interact with the page effectively.
1.1 Information & Relationships
‘strong’ and ’em’ tags must be used instead of ‘b’ and ‘i’.
Proper HTML list structures (‘ol’, ‘ul’, and ‘dl’>) should be implemented.
Labels must be correctly associated with form fields using ‘label’ tags.
Data tables should include proper column and row headers.
1.2 Text Spacing
The line height should be at least 1.5 times the font size.
Paragraph spacing must be at least 2 times the font size.
Letter and word spacing should be set for readability.
1.3 Bypass Blocks
“Skip to content” links should be provided to allow users to bypass navigation menus.
1.4 Page Titles
Unique and descriptive page titles must be included.
2. Page Navigation
A well-structured navigation system helps users quickly find information and move between pages. Consistency and multiple navigation methods improve usability and accessibility for all users, including those with assistive technologies.
2.1 Consistency
The navigation structure should remain the same across all pages.
The position of menus, search bars, and key navigation elements should not change.
Common elements like logos, headers, footers, and sidebars should appear consistently.
Labels and functions of navigation buttons should be identical on every page (e.g., a “Buy Now” button should not be labeled differently on other pages).
2.2 Multiple Navigation Methods
Users should have at least two or more ways to navigate content. These may include:
A homepage with links to all pages
Search functionality
A site map
A table of contents
Primary and secondary navigation menus
Repetition of important links in the footer
Breadcrumb navigation
Skip links should be available to jump directly to the main content.
3. Language
Defining the correct language settings on a webpage helps screen readers and other assistive technologies interpret and pronounce text correctly. Without proper language attributes, users relying on these tools may struggle to understand the content.
3.1 Language of the Page
The correct language should be set for the entire webpage using the lang attribute (e.g., ‘html lang=”en”‘).
The declared language should match the primary language of the content.
Screen readers should be able to detect and read the content in the correct language.
If the page contains multiple languages, the primary language should still be properly defined.
3.2 Language of Parts
The correct language should be assigned to any section of text that differs from the main language using the lang attribute (e.g.,[span lang=”fr” Bonjour/span]).
Each language change should be marked properly to ensure correct pronunciation by screen readers.
Language codes should be accurately applied according to international standards (e.g., lang=”es” for Spanish).
4. Heading Structure
Headings provide structure to web pages, making them easier to navigate for users and assistive technologies. A logical heading hierarchy ensures clarity and improves readability.
The presence of a single ‘h1’ tag must be ensured.
A logical heading hierarchy from ‘h1’ to ‘h6’ should be followed.
Headings must be descriptive and should not be abbreviated.
5. Multimedia Content
Multimedia elements like audio and video must be accessible to all users, including those with hearing or visual impairments. Providing transcripts, captions, and audio descriptions ensures inclusivity.
5.1 Audio & Video
Text alternatives must be provided for audio and video content.
Transcripts should be included for audio-only content.
Video content must have transcripts, subtitles, captions, and audio descriptions.
5.2 Captions
Pre-recorded video content must include captions that are synchronized and accurate.
Non-speech sounds, such as background noise and speaker identification, should be conveyed in captions.
Live content must be accompanied by real-time captions.
5.3 Audio Control
If audio plays automatically for more than three seconds, controls for pause, play, and stop must be provided.
6. Animation & Flashing Content
Animations and flashing elements can enhance user engagement, but they must be implemented carefully to avoid distractions and health risks for users with disabilities, including those with photosensitivity or motion sensitivities.
6.1 Controls for Moving Content
A pause, stop, or hide option must be available for any moving or auto-updating content.
The control must be keyboard accessible within three tab stops.
The movement should not restart automatically after being paused or stopped by the user.
Auto-playing content should not last longer than five seconds unless user-controlled.
6.2 Flashing Content Restrictions
Content must not flash more than three times per second to prevent seizures (photosensitive epilepsy).
If flashing content is necessary, it must pass a photosensitive epilepsy analysis tool test.
Flashing or blinking elements should be avoided unless absolutely required.
7. Images
Images are a vital part of web design, but they must be accessible to users with visual impairments. Screen readers rely on alternative text (alt text) to describe images, ensuring that all users can understand their purpose.
7.1 Alternative Text
Informative images must have descriptive alt text.
Decorative images should use alt=”” to be ignored by screen readers.
Complex images should include detailed descriptions in surrounding text.
Functional images, such as buttons, must have meaningful alt text (e.g., “Search” instead of “Magnifying glass”).
7.2 Avoiding Text in Images
Text should be provided as actual HTML text rather than embedded in images.
Proper use of color and contrast is essential for users with low vision or color blindness. Relying solely on color to convey meaning can make content inaccessible, while poor contrast can make text difficult to read.
8.1 Use of Color
Color should not be the sole method of conveying meaning.
Graphs and charts must include labels instead of relying on color alone.
8.2 Contrast Requirements
A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text must be maintained.
9. Keyboard Accessibility
Keyboard accessibility is essential for users who rely on keyboard-only navigation due to mobility impairments. All interactive elements must be fully accessible using the Tab, Arrow, and Enter keys.
9.1 Keyboard Navigation
All interactive elements must be accessible via keyboard navigation.
9.2 No Keyboard Trap
Users must be able to navigate out of any element without getting stuck.
9.3 Focus Management
Focus indicators must be visible.
The focus order should follow the logical reading sequence.
10. Link Purpose
Links play a crucial role in website navigation, helping users move between pages and access relevant information. However, vague or generic link text like “Click here” or “Read more” can be confusing, especially for users relying on screen readers.
Link text should be clearly written to describe the destination (generic phrases like “Click here” or “Read more” should be avoided).
Similar links should be distinguished with unique text or additional context.
Redundant links pointing to the same destination should be removed.
Links should be visually identifiable with underlines or sufficient color contrast.
ARIA labels should be used when extra context is needed for assistive technologies.
11. Error Handling
Proper error handling ensures that users can easily identify and resolve issues when interacting with a website. Descriptive error messages and preventive measures help users avoid frustration and mistakes, improving overall accessibility.
11.1 Error Identification
Errors must be clearly indicated when a required field is left blank or filled incorrectly.
Error messages should be text-based and not rely on color alone.
The error message should appear near the field where the issue occurs.
11.2 Error Prevention for Important Data
Before submitting legal, financial, or sensitive data, users must be given the chance to:
Review entered information.
Confirm details before final submission.
Correct any mistakes detected.
A confirmation message should be displayed before finalizing critical transactions.
12. Zoom & Text Resizing
Users with visual impairments often rely on zooming and text resizing to read content comfortably. A well-designed website should maintain readability and functionality when text size is increased without causing layout issues.
12.1 Text Resize
Text must be resizable up to 200% without loss of content or functionality.
No horizontal scrolling should occur unless necessary for complex content (e.g., tables, graphs).
12.2 Reflow
Content must remain readable and usable when zoomed to 400%.
No truncation, overlap, or missing content should occur.
When zooming to 400%, a single-column layout should be used where possible.
Browser zoom should be tested by adjusting the display resolution to 1280×1080.
13. Form Accessibility
Forms are a critical part of user interaction on websites, whether for sign-ups, payments, or data submissions. Ensuring that forms are accessible, easy to navigate, and user-friendly helps people with disabilities complete them without confusion or frustration.
13.1 Labels & Instructions
Each form field must have a clear, descriptive label (e.g., “Email Address” instead of “Email”).
Labels must be programmatically associated with input fields for screen readers.
Required fields should be marked with an asterisk (*) or explicitly stated (e.g., “This field is required”).
Error messages should be clear and specific (e.g., “Please enter a valid phone number in the format +1-123-456-7890”).
13.2 Input Assistance
Auto-fill attributes should be enabled for common fields (e.g., name, email, phone number).
Auto-complete suggestions should be provided where applicable.
Form fields should support input hints or tooltips for better guidance.
Icons or visual indicators should be used where necessary (e.g., a calendar icon for date selection).
Dropdowns, radio buttons, and checkboxes should be clearly labeled to help users make selections easily.
