Accessibility standard
WCAG 2.2 AA
The global technical standard for accessible digital experiences.
Applies to: EveryoneWhat it is
The Web Content Accessibility Guidelines are the international benchmark for digital accessibility.
WCAG 2.2 AA is the level most laws, contracts, and procurement rules reference today.
It is structured around four principles: Perceivable, Operable, Understandable, and Robust.
Who must comply
- Anyone building public-facing web or mobile experiences
- Vendors selling to governments, enterprises, or education
- Teams contractually required to meet accessibility standards
Key requirements
- Perceivable: alt text, captions, color contrast, resizable text
- Operable: full keyboard support, focus visible, no seizure-inducing motion
- Understandable: clear language, consistent navigation, helpful errors
- Robust: clean semantic markup, valid ARIA, parseable code
Risks of non-compliance
Failing WCAG is the underlying cause of nearly every accessibility lawsuit and procurement disqualification.

How Scale helps
Every site we build ships to WCAG 2.2 AA by default. For existing sites, we audit, remediate, and certify.
