Accessibility Audit
A structured assessment against WCAG, combining automated tooling with the manual testing that finds most real problems.
Definition
An accessibility audit evaluates a product against defined success criteria. Automated tools catch a minority of issues; the majority require manual testing with keyboard and assistive technology.
Craft convention. True because the industry converged on it. Breaking it costs familiarity, not correctness.
On this plate
Reach for this when
- Establishing a baseline.
- Before a release with legal or contractual accessibility requirements.
- Producing an accessibility statement.
Common mistakes
- Relying on automated results.
- Auditing pages rather than flows.
- Findings with no severity or remediation.
- No retest after fixes.
A workable audit process
- 1
Define scope
Which pages, which flows, which conformance level, which assistive technology pairings.
- 2
Run automated tooling
axe, Lighthouse or equivalent. This finds contrast, missing labels, landmark and ARIA misuse quickly.
- 3
Keyboard pass
Complete every flow with no mouse. This finds most operability failures.
- 4
Screen reader pass
At least one desktop and one mobile pairing on the primary flows.
- 5
Zoom and reflow pass
400 percent zoom, and 200 percent text-only zoom.
- 6
Cognitive and content pass
Language clarity, error recovery, timeouts, consistent help.
- 7
Report with severity and location
Criterion, what fails, where, and a concrete remediation.
