Essential Guidelines and Standards for Accessibility Testing

Accessibility testing isn't just a best practice—it's often a legal requirement. Understanding the relevant guidelines and standards is crucial for building inclusive digital experiences and avoiding potential legal headaches. This section breaks down the key standards you need to know.

Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) are the internationally recognized benchmarks for digital accessibility. Developed by the World Wide Web Consortium (W3C), WCAG offers a set of success criteria categorized by four main principles: Perceivable, Operable, Understandable, and Robust (POUR).

• Perceivable: Information and user interface components must be presentable to users in ways they can perceive. This means providing text alternatives for non-text content, captions and other alternatives for multimedia, and making content adaptable to different presentations without losing information or structure.

• Operable: User interface components and website navigation must be usable. This includes ensuring all functionality is available from a keyboard, giving users enough time to interact with time-sensitive content, and avoiding design elements that could trigger seizures. Users should have ways to find information easily.

• Understandable: Information and the operation of the user interface must be understandable. This involves making text content readable and predictable and helping users avoid and correct mistakes.

• Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. This ensures compatibility with current and future technologies.

WCAG offers three levels of conformance: A (lowest), AA, and AAA (highest). Most organizations aim for WCAG 2.1 Level AA conformance, which provides a good balance of accessibility and practicality.

Americans with Disabilities Act (ADA) Compliance

In the United States, the Americans with Disabilities Act (ADA) prohibits discrimination based on disability. While the ADA doesn't explicitly mention websites, courts have consistently held that it applies to digital properties of businesses open to the public. This means your website and other digital services need to be accessible to people with disabilities. Failure to comply can result in lawsuits and expensive fines. Following WCAG guidelines is generally accepted as a way to meet ADA requirements for website accessibility.

Section 508 Requirements

Section 508 of the Rehabilitation Act specifically addresses accessibility in information and communication technology (ICT) used by the federal government. It mandates that federal agencies must make their electronic and information technology accessible to people with disabilities, including websites, software, and other digital content. Section 508 requires conformance with WCAG 2.0 Level AA, ensuring that federal agencies' digital services are usable by everyone. While Section 508 directly applies to federal agencies, it also influences accessibility standards in the private sector and often serves as a helpful model for organizations looking to improve their digital accessibility.
