Accessible on Paper, Broken in Reality: Why Accessibility User Testing Changes Everything
taught by: Charlii Parker
Session Summary
Accessibility can pass every audit and still fail a real person.
This session exposes the gap between technical compliance and lived experience and shows why user testing is where accessibility becomes real.
Description
Conformance ≠ usability
Passing audits ≠ usable experiences
Assistive tech + real people expose the gaps
We’ve all seen the green audit report. The criteria are met. The issues are closed. The organisation moves on.
Then a real person tries to complete a task and the cracks appear.
In this session, I’ll unpack the gap between technical conformance and actual human experience. Drawing from real accessibility user testing sessions, I’ll share examples of products that technically met WCAG but broke down in workflow, cognitive load, recovery patterns, or interaction fatigue. Not because teams didn’t care. Not because standards are wrong. But because compliance alone doesn’t measure usability.
We’ll explore where accessibility commonly fails in the space between components, how assistive technology behaves in the real world, and why “can complete the task” is a dangerously low bar.
This is not a standards lecture. It’s a practical, evidence-based look at what happens when disabled users are brought into the testing process and how that changes design decisions, stakeholder conversations, and product risk.
If you design, build, test, approve, or fund digital products, this session will give you a clearer framework for moving beyond checkbox accessibility and toward meaningful access.
Practical Skills
- Distinguish between technical WCAG conformance and real-world usability outcomes for disabled users.
- Identify common failure points that emerge during accessibility user testing, even in products that pass audits.
- Apply practical strategies to integrate accessibility user testing into existing design, development, and governance workflows.
