WCAG 2.2 on Drupal: complete compliance checklist

WCAG 2.2 in 60 seconds

WCAG 2.2 (pronounced 'wuh-cag 2.2') is the World Wide Web Consortium's globally adopted standard for web accessibility, published October 2023, defining 87 testable success criteria organised under four principles: Perceivable, Operable, Understandable, Robust.

Drupal accessibility — what you are starting with

Drupal's commitment to accessibility is institutional: a dedicated accessibility maintainer, an a11y gate on core changes, and an accessibility-focused community. Drupal is the most-deployed CMS in higher education and government for this reason.

WCAG 2.2 setup checklist for Drupal

1. Use core themes (Olivero, Claro): Both target WCAG 2.1 AA out-of-box.

2. Audit contributed modules: Each module ships its own templates; audit before deployment.

3. Editor training: Use the Editoria11y module to catch authoring failures in CKEditor.

Common WCAG 2.2 failures on Drupal

• Custom modules introducing inaccessible markup

• Inaccessible WYSIWYG content from editors

• Contributed modules with weaker a11y

• Layout Builder customisations

Putting it together

Combine WCAG 2.2's AA requirements with Drupal's native tooling. Bake accessibility into your component library and editorial workflow; instrument axe-core in CI for regression.
