Design systems audit checklist for WCAG 3.0 adoption

Design · 6 min read

WCAG 3.0 reframes accessibility around outcomes rather than a fixed set of checkpoints, which changes how design systems should measure success. Start by mapping your existing tokens and components to the accessibility outcomes that matter for your users—contrast, perceivability, operability, and understanding—so you can target the biggest gaps first.

Next, create an automated baseline: integrate visual contrast and semantic testing into CI using both synthetic tools (contrast analyzers, ARIA linting) and human-in-the-loop checks for keyboard and screen reader flows. Prioritize changes that affect many screens—global tokens, typography scales, and focus styles—and defer heavier UI rewrites to a roadmap tied to user impact metrics.

Finally, update documentation and governance: publish clear accessibility intent and usage guidelines in your component docs, add accessible examples and failing states, and record design decisions in your system’s changelog. Make accessibility reviews a formal gate in your release process so adjustments to tokens or components trigger an accessibility assessment rather than an afterthought.
