WCAG 2.2 is the current version of the Web Content Accessibility Guidelines, and in 2026 it has become the benchmark for accessible, legally defensible websites. This pillar guide is your single starting point: it explains what WCAG 2.2 is, breaks down all nine new success criteria, shows exactly what changed from WCAG 2.1, maps the standard to the laws that apply to you, and gives you a practical path to implement and test it. Throughout, you'll find links to deeper guides on each topic so you can go as deep as you need.
TL;DR: WCAG 2.2 keeps everything from WCAG 2.1, adds nine new success criteria (focused on keyboard focus visibility, easier interactions, larger targets, and accessible authentication), and removes the old 4.1.1 Parsing requirement. Aim for Level AA, prioritize the new criteria, run an accessibility audit with the right testing tools, and bake testing into your workflow.
For a plain-English overview of what WCAG compliance requires across the standards, start here.
WCAG is developed by the World Wide Web Consortium (W3C) to make digital content accessible to people with disabilities. It is organized around four principles - POUR:
WCAG 2.2 is backward-compatible with 2.1: meeting 2.2 means you also meet 2.1. Its new criteria were identified through extensive user research and litigation analysis, with a strong emphasis on cognitive, low-vision, and motor accessibility.
Every success criterion is assigned a conformance level. Level A is the minimum baseline; Level AA is the standard most laws require and the practical target for nearly every website; Level AAA is the highest bar, reserved for specialized or high-stakes content. Unless you have a specific reason to go further, target WCAG 2.2 Level AA.
These nine criteria are the heart of WCAG 2.2. Several relate to keyboard focus management and pointer interactions:
Work through every criterion with our interactive WCAG 2.2 checklist, which lists all 55 success criteria with how to fix and test each. Run a free WCAG 2.2 scan to see which of these criteria your site currently fails.
The headline change is the nine added criteria above. The other notable change is a removal:
4.1.1 Parsing was removed. It previously required clean, valid HTML so assistive technologies could interpret content. Modern browsers and screen readers now handle malformed HTML reliably, so the focus has shifted to actual user experience rather than code validity. Clean, semantic HTML remains a best practice - it's simply no longer a formal success criterion.
WCAG itself is a technical standard, not a law - but it's the standard nearly every accessibility regulation references. WCAG 2.2 AA is quickly becoming the expected benchmark worldwide. Here's how it maps to the major frameworks:
The latest version of the Web Content Accessibility Guidelines from the W3C. It builds on WCAG 2.1 and the POUR principles, adding nine new success criteria for users with cognitive, low-vision, and motor disabilities.
Nine - covering focus visibility and appearance, dragging movements, target size, consistent help, redundant entry, and accessible authentication.
Success criterion 4.1.1 Parsing, because modern browsers and assistive tech now handle imperfect HTML reliably. Clean, semantic HTML is still best practice.
WCAG is a standard, not a law, but it's the standard most laws reference - including the ADA, Section 508, the EAA, and AODA. WCAG 2.2 AA is becoming the expected benchmark and is being incorporated into regulations like EN 301 549.
WCAG 2.2 keeps everything in 2.1, adds nine new criteria, and removes 4.1.1 Parsing. The additions emphasize focus visibility, easier interactions, larger targets, and accessible authentication and help.
Level A is the minimum baseline, Level AA is the standard most laws require and the practical target for most sites, and Level AAA is the highest level for specialized content. Most organizations target WCAG 2.2 Level AA.
Combine automated scanning tools with manual keyboard and screen reader testing. Automation catches code-level issues like contrast and missing alt text quickly; manual testing confirms judgment-based criteria such as focus order, target size, and accessible authentication.

WCAG 2.2 is an evolution, not a reinvention: master the nine new criteria, retire your reliance on 4.1.1 Parsing, and target Level AA. Audit your site, prioritize the new requirements, remediate by severity, document your conformance, and monitor continuously. Use the linked guides and tools above to go deeper on any piece - together they give you everything you need to meet the standard that defines accessible, compliant digital experiences in 2026.
