Everyone agrees that accessibility is important. We should make things usable for people with disabilities. That’s the common wisdom. And it’s not wrong. But it’s woefully incomplete.
The hard truth is that treating accessibility as a final QA step is a recipe for disaster. It’s expensive, it’s demoralizing, and it leads to rushed, compromised solutions. True accessibility is built in, not bolted on.
This isn’t about compliance for compliance’s sake. It’s about building better, more robust digital products for everyone. It’s about smart workflow. It’s about good business.
Let’s break down what a real accessibility QA process looks like, and how to integrate it from the ground up.
1. Understanding the Core Principles
Before you can test, you need to understand what you’re testing for. The Web Content Accessibility Guidelines (WCAG) are the international standard. They’re based on four principles, often remembered by the acronym POUR:
- Perceivable: Users must be able to perceive the information being presented (it can’t be invisible to all of their senses).
- Operable: Users must be able to operate the interface (the interface cannot require interaction that a user cannot perform).
- Understandable: Users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond the user’s understanding).
- Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
These principles are the bedrock. Everything else flows from them. Don’t just skim them. Understand what they mean in practice for the interfaces you’re building.
2. Keyboard Navigation: The Unsung Hero
The most common and impactful accessibility issue? Lack of keyboard operability. Many users, including those with motor impairments or who use screen readers, navigate interfaces solely with a keyboard. If your design isn’t keyboard-friendly, it’s fundamentally broken for them.
Checklist Items:
- Can all interactive elements (links, buttons, form fields, menus) be reached using the Tab key?
- Is the focus indicator clearly visible? Can you tell which element is currently selected?
- Does the focus order make logical sense? (e.g., left to right, top to bottom)
- Can you operate all functionality (dropdowns, modals, accordions) using only the keyboard? (Enter, Space, Esc, Arrow keys)
- Is there a way to
Frequently asked questions
What are the core principles of web accessibility?
The core principles are Perceivable, Operable, Understandable, and Robust (POUR), as defined by the Web Content Accessibility Guidelines (WCAG).
How often should accessibility testing be performed?
Accessibility testing should be integrated throughout the entire design and development process, not just at the end. This includes design reviews, content creation, development, and final QA.
What are common accessibility issues to look for?
Common issues include lack of keyboard navigation, insufficient color contrast, missing alt text for images, non-descriptive link text, and lack of clear focus indicators.
Can automated tools catch all accessibility problems?
No, automated tools can catch some issues, but they cannot identify all accessibility barriers. Manual testing, especially with assistive technologies, is crucial.
