WCAG 2.2 — The 4 Principles Explained
ADAGuard tests all four WCAG principles — known as POUR — across 50+ success criteria.
Principle 1: Perceivable
Information and UI components must be presentable to users in ways they can perceive.
- 1.1.1 Non-text Content (alt text)
- 1.3.1 Info & Relationships
- 1.4.3 Contrast Minimum
- 1.4.4 Resize Text
Principle 2: Operable
UI components and navigation must be operable by all users.
- 2.1.1 Keyboard Access
- 2.4.1 Bypass Blocks
- 2.4.3 Focus Order
- 2.4.6 Headings & Labels
Principle 3: Understandable
Information and UI operation must be understandable.
- 3.1.1 Language of Page
- 3.2.1 On Focus
- 3.3.1 Error Identification
- 3.3.2 Labels or Instructions
Principle 4: Robust
Content must be robust enough to be interpreted by a wide variety of user agents.
- 4.1.1 Parsing
- 4.1.2 Name, Role, Value
- 4.1.3 Status Messages
WCAG Conformance Levels
WCAG defines three levels of conformance. ADAGuard tests Level A and Level AA.
Minimum conformance. Must pass to avoid complete exclusion of users with disabilities.
Standard conformance. Required by ADA, Section 508, EN 301 549, and most accessibility laws globally.
Enhanced conformance. Exceeds legal requirements. Not required for entire sites but recommended for key content.
WCAG Checker — FAQ
Common questions about WCAG 2.2 compliance and ADAGuard.
What is a WCAG checker?
A WCAG checker is an automated tool that scans your website against the Web Content Accessibility Guidelines (WCAG) — the internationally recognised standard for web accessibility. It identifies which success criteria your site fails and explains how to fix each issue.
What version of WCAG does ADAGuard check?
ADAGuard tests against WCAG 2.2 Level A and Level AA — the standard referenced by the ADA, Section 508, and most global accessibility regulations. Coverage spans all 4 WCAG principles (Perceivable, Operable, Understandable, Robust) with approximately 78% automated coverage.
Can automated tools check all WCAG criteria?
No automated tool can check 100% of WCAG criteria. Some criteria require human judgment — for example, whether alt text is descriptively accurate, or whether content is written in plain language. ADAGuard automates ~78% of testable criteria and flags items requiring manual review.
What WCAG level do I need to comply with?
WCAG 2.1/2.2 Level AA is the standard required by the ADA (US), the European Accessibility Act / EN 301 549 (EU — enforced June 2025), AODA (Canada), and most other web accessibility laws. Level A is the minimum and Level AAA is recommended for high-priority content but not required across entire sites. WCAG 3.0 is still a Working Draft and is not expected to be finalised before 2028.
Can I use this as a WCAG 2.1 or WCAG 2.0 checker?
Yes. WCAG is backwards-compatible: every WCAG 2.0 and WCAG 2.1 success criterion is carried forward into WCAG 2.2 (with one exception — 4.1.1 Parsing, removed in 2.2 as obsolete). A WCAG 2.2 scan therefore also tests your site against WCAG 2.1 Level AA and WCAG 2.0 Level AA — the versions still cited by AODA, EN 301 549, and many older procurement requirements.
Is this a WCAG test, a validator, or a scanner?
All three describe what ADAGuard does, with one distinction worth knowing: a traditional WCAG validator checks static HTML markup, while a WCAG test or scan loads your live page in a real browser first. ADAGuard does the latter — it renders your page with JavaScript executed, then validates the rendered DOM against WCAG 2.2 success criteria. That catches issues in dynamic content, React/Vue components, and cookie banners that static validators never see.
Do EU public-sector websites (municipalities, universities) need WCAG testing?
Yes. The EU Web Accessibility Directive has required public-sector bodies — municipalities, government agencies, universities, and schools — to meet WCAG 2.1 Level AA since 2021, including a published accessibility statement and periodic monitoring by national authorities. The European Accessibility Act extended similar obligations to private-sector e-commerce and services from June 2025. ADAGuard tests the WCAG criteria behind both laws, and running a scan is free.
How long does a WCAG check take?
A single-page WCAG check takes 10–30 seconds. A 100-page site scan takes approximately 2–3 minutes using ADAGuard's parallel scanning engine.
Can I automate WCAG checks in my CI/CD pipeline?
Yes. ADAGuard's REST API (Professional plans and above) lets you trigger scans programmatically, set a minimum score threshold, and fail your build when new WCAG violations are introduced. You can also schedule recurring WCAG audits (daily, weekly, or monthly) so compliance is monitored continuously — not just at launch.
