WordPress Accessibility Testing Framework: End the Guesswork

This week, WordPress Accessibility Day 2025 brought together accessibility professionals from around the world to share insights on building truly inclusive websites. One session stood out for its actionable, systematic approach to a challenge many WordPress teams face: how do you actually test whether your themes and plugins meet accessibility standards?

Why This Session Matters

Rodrigo Ibraim Teixeira, a digital accessibility consultant with over 15 years of development experience, presented “Technical Checklist: Testing WordPress Themes and Plugins for Accessibility.” Rather than diving into abstract concepts, Rodrigo shared something immediately useful—a structured checklist based on Brazilian accessibility standards (ABNT NBR 17025) that directly aligns with WCAG guidelines.

For WordPress teams managing compliance requirements, this practical framework addresses a common gap: knowing you need to be accessible versus knowing exactly what to check and how to verify it.

Key Insights That Challenge Common Assumptions

Accessibility isn’t just about design choices—it’s about who can use your website. Rodrigo framed accessibility as a bridge connecting content to users. When that bridge has gaps, we exclude people. When we build it correctly, we welcome everyone.

The Brazilian standard he referenced organizes WCAG’s success criteria into actionable categories, each focusing on a critical part of user experience:

Keyboard Navigation Must Be Predictable and Escape-Proof The checklist emphasizes that keyboard interaction goes far beyond “can you press Tab?” Every interactive element needs a visible focus indicator. Tab order must follow logical reading patterns. Users must never get trapped in popups or menus. These aren’t nice-to-have features—they’re fundamental requirements for people who can’t use a mouse.

A particularly eye-opening requirement: single-key shortcuts (like pressing “S” to search) must let users turn them off, remap them, or make them context-specific. Why? Because speech recognition software users might accidentally trigger shortcuts when dictating text. This kind of nuanced consideration shows how accessibility requirements anticipate real-world usage patterns.

Images Require Context-Specific Description Strategies The session clarified something many teams struggle with: not all images need the same treatment. Decorative images should be hidden from screen readers entirely (using empty alt text). Informative images need descriptive alt text conveying meaning. Functional images (like search icons) should describe the action, not the image itself. Complex images like charts require both short alt text and detailed long descriptions.

This category-based approach eliminates the common mistake of either over-describing decorative elements or under-describing functional ones.

Tools Accelerate Detection, But Can’t Replace Understanding Rodrigo demonstrated how automated tools like WAVE and AMAWeb‘s validator can quickly identify technical issues—missing alt text, color contrast problems, structural gaps. But he emphasized something critical: these tools are assistants, not replacements for the checklist. They spot obvious code problems instantly, freeing up time for expert judgment on complex usability issues.

The testing approach combines automated scanning with manual verification using the structured checklist. This dual method catches both technical violations and experience problems that tools miss.

Why This Framework Works for WordPress Teams

What makes this approach valuable is its structure. The checklist uses a simple meets/does-not-meet/not-applicable scoring system with space for comments and code references. This makes it practical for team collaboration—developers can document exactly what needs fixing, where it’s located, and why it matters.

The framework covers the essentials systematically:

Keyboard interaction patterns and focus management
Image alternative text strategies by image type
List semantics and proper HTML structure
Headers hierarchy and landmark regions
Link clarity and navigation predictability
Form labels and error messaging
Color contrast and text readability

Each category includes both requirements (must-fix issues that prevent usage) and recommendations (improvements that enhance experience). This prioritization helps teams focus limited resources on eliminating barriers first, then improving overall quality.

Making Accessibility Testing Systematic Rather Than Sporadic

The broader implication of this session is that accessibility testing doesn’t have to be overwhelming or vague. With a structured checklist aligned to WCAG standards, testing becomes a repeatable process rather than guesswork. Teams can verify compliance systematically, document results clearly, and track progress over time.

For organizations managing WordPress sites under compliance requirements, this kind of practical framework bridges the gap between knowing you need to meet WCAG AA standards and actually verifying you’ve done it.
