WCAG 3.0 Guideline Categories
WCAG 3.0 replaces the 4 POUR principles (Perceivable, Operable, Understandable, Robust) with 12 functional categories. This shift moves from abstract principles to concrete, outcome-focused groupings that better reflect how people actually use digital products.
From 4 Principles to 12 Categories
The familiar POUR framework served accessibility well for over 15 years. WCAG 3.0 evolves this into 12 granular categories that better capture the full spectrum of user needs.
All 12 Guideline Categories
Each category groups related accessibility outcomes together. Categories marked as "New" or "Expanded" represent areas where WCAG 3.0 goes significantly beyond what WCAG 2.x covered.
Images and Media
Covers alternatives for visual and audio content across nine guidelines: image alternatives, figure captions, non-text alternatives, transcripts, captions, audio descriptions, sign language, single sense, and accessible media players. This category ensures all non-text content has an equivalent accessible form.
Maps to: WCAG 2.x Guideline 1.1, 1.2
Text and Wording
Addresses readable, clear language support including reading level, language identification, abbreviations, and plain language requirements. Ensures textual content is understandable by the widest possible audience.
Maps to: WCAG 2.x Guideline 3.1
Interactive Components
Focuses on keyboard and pointer focus management, interactive controls, focus order, and visible focus indicators. Ensures all interactive elements are discoverable, operable, and communicate their state clearly.
Maps to: WCAG 2.x Guideline 2.1, 2.4
Input/Operation
Covers keyboard, pointer, speech, and gesture input methods. Ensures users can operate content through any input modality without being locked into a single mechanism, and that complex gestures have simple alternatives.
Maps to: WCAG 2.x Guideline 2.1, 2.5
Error Handling
Addresses error detection, prevention, and correction. Users must be informed of errors in an accessible way, given suggestions for correction, and provided the ability to review and undo submissions.
Maps to: WCAG 2.x Guideline 3.3
Animation and Movement
Protects physical safety by addressing seizure risks, motion sickness, and distracting animations. Requires that animations can be paused, stopped, or hidden, and that flashing content stays within safe thresholds.
Maps to: WCAG 2.x Guideline 2.3
Layout
Ensures recognizable, navigable page structures with proper visual hierarchy, contrast, spacing, and responsive design. Covers both visual presentation and the underlying semantic structure that assistive technologies rely on.
Maps to: WCAG 2.x Guideline 1.3, 1.4
Consistency Across Views
Ensures predictable navigation and consistent behavior across different views, pages, and states. Significantly expanded from WCAG 2.x to cover multi-step processes, cross-platform consistency, and pattern predictability.
Maps to: WCAG 2.x Guideline 3.2 (expanded significantly)
Process and Task Completion
Addresses cognitive accessibility by ensuring multi-step processes are manageable, progress is saved, and users can complete tasks without excessive cognitive load. This category is largely new territory not covered by WCAG 2.x.
Maps to: Largely NEW in WCAG 3.0
Policy and Protection
Covers risk mitigation, algorithmic fairness, and organizational policies that protect users from harm. This entirely new category addresses dark patterns, bias in automated decisions, and privacy considerations for people with disabilities.
Maps to: Entirely NEW in WCAG 3.0
Help and Feedback
Ensures support mechanisms are available, discoverable, and accessible. Significantly expanded beyond WCAG 2.x to include contextual help, feedback channels, documentation accessibility, and human support options.
Maps to: WCAG 2.x Guideline 3.3 (expanded)
User Control
Addresses assistive technology compatibility, user customization, and personalization options. Significantly expanded from WCAG 2.x Robust principle to include user preferences, settings persistence, and adaptive interfaces.
Maps to: WCAG 2.x Guideline 4.1 (expanded)
What's New in WCAG 3.0 Categories
While many WCAG 3.0 categories map directly to existing WCAG 2.x guidelines, several represent entirely new territory or significant expansions.
NewEntirely New Categories
Category 9: Process and Task Completion
Cognitive accessibility for multi-step tasks, progress saving, and reducing mental load. WCAG 2.x had no direct equivalent for this critical area.
Category 10: Policy and Protection
Algorithmic fairness, dark pattern prevention, and organizational responsibility. Reflects the modern digital landscape where automated systems can create accessibility barriers.
ExpandedSignificantly Expanded Categories
Category 8: Consistency Across Views
Goes well beyond WCAG 2.x Guideline 3.2 to cover cross-platform consistency, multi-step process predictability, and pattern coherence.
Category 11: Help and Feedback
Expands beyond error assistance to include contextual help, accessible documentation, feedback channels, and human support options.
Category 12: User Control
Evolves the Robust principle into comprehensive user agency, covering personalization, settings persistence, and adaptive interface support.
