WCAG 3.0 is a future version of the Web Content Accessibility Guidelines currently under development by the W3C. Sometimes referred to as the Silver project, it proposes a new structure for evaluating accessibility that includes outcome-based testing, scoring models, and broader coverage of digital technologies beyond traditional websites.
WCAG 3.0
Key facts about WCAG 3.0
- Published by: World Wide Web Consortium (W3C)
- Status: Working Draft (not yet finalized)
- Type: Next-generation accessibility guidance framework
- Project name: Originally developed under the Silver project
- Proposed model: Bronze, Silver, Gold conformance levels
- Scope: Websites, mobile apps, software platforms, and emerging technologies
What is the WCAG 3.0 definition?
WCAG 3.0 refers to the next generation of the Web Content Accessibility Guidelines, expanding the framework introduced in WCAG 2.0, WCAG 2.1, and WCAG 2.2 being developed by the World Wide Web Consortium (W3C). The new version aims to expand accessibility guidance beyond traditional web content and introduce a more flexible scoring model for evaluating accessibility across websites, applications, and emerging technologies.
WCAG 3.0 is still evolving. For a deeper explanation of the proposed framework and expected changes compared to WCAG 2.x, see our guide to WCAG 3.0.
WCAG 3.0 meaning
WCAG 3.0 stands for Web Content Accessibility Guidelines version 3.0.
These guidelines are part of an international effort to improve accessibility for people with disabilities when interacting with digital content, such as:
- Websites
- Mobile applications
- Software platforms
- Digital documents
- Emerging technologies
The guidelines are developed by the World Wide Web Consortium (W3C) through its Web Accessibility Initiative (WAI).
WCAG provides technical recommendations that help designers, developers, and organizations create digital content that is usable by people who rely on assistive technologies.
Why WCAG 3.0 is being developed
Earlier versions of WCAG, including WCAG 2.0, WCAG 2.1, and WCAG 2.2, introduced success criteria designed to improve accessibility for websites and digital interfaces.
However, accessibility needs and technology environments have evolved significantly. WCAG 3.0 is being developed to address several challenges in the existing framework.
These include:
- Limited guidance for emerging technologies
- Difficulty measuring accessibility outcomes
- A pass or fail evaluation model that can be restrictive
- Accessibility needs beyond traditional web pages
WCAG 3.0 aims to introduce a more flexible and comprehensive approach to evaluating accessibility across digital experiences.
The Silver project
WCAG 3.0 has often been referred to as the Silver project, which was the early working name used during its development.
The goal of the Silver initiative is to create a more adaptable accessibility standard that can evolve alongside new technologies.
Key ideas explored in the Silver project include:
- Outcome-based accessibility evaluation
- Expanded guidance for different user needs
- Improved testing methods
- Scoring models rather than strict pass or fail criteria
The term “Silver” is still sometimes used in discussions about WCAG 3.0 development.
Key differences between WCAG 2.x and WCAG 3.0
WCAG 3.0 introduces several structural changes compared with earlier versions of the Web Content Accessibility Guidelines.
Topic | WCAG 2.x | WCAG 3.0 |
|---|---|---|
Scope | Primarily web content | Broader digital technologies |
Coverage | Websites and web applications | Websites, mobile apps, software, and emerging technologies |
Evaluation model | Pass or fail success criteria | Proposed scoring and outcome-based evaluation |
Structure | Success criteria grouped by levels (A, AA, AAA) | More flexible framework designed to evolve with technology |
Outcome-based evaluation
Earlier WCAG versions focused heavily on technical success criteria.
WCAG 3.0 introduces outcome-based testing, which focuses more directly on whether users can successfully interact with content.
Accessibility scoring model
Instead of a strict pass or fail system, WCAG 3.0 proposes a scoring model that evaluates accessibility performance across different criteria.
This approach may provide a more nuanced way of measuring accessibility improvements.
Is WCAG 3.0 finalized?
No. WCAG 3.0 is still under development and has not yet been finalized.
The W3C continues to release working drafts as part of the standards development process.
Organizations that are currently improving accessibility generally continue to focus on WCAG 2.1 and WCAG 2.2, which are widely referenced in accessibility regulations and industry guidance.
Future regulatory frameworks may eventually reference WCAG 3.0 once it becomes a stable recommendation.
WCAG 3.0 and accessibility regulations
Many accessibility laws and policies reference WCAG as a technical benchmark for digital accessibility.
Examples include:
- ADA digital accessibility guidance in the United States
- Section 508 standards for federal agencies
- The European Accessibility Act
- Public sector accessibility regulations in several countries
While these regulations currently reference earlier WCAG versions, WCAG 3.0 may influence future accessibility policies once it becomes finalized.
For example, the ADA Title II digital accessibility rule references WCAG 2.1 Level AA as the accessibility standard for government websites and mobile applications.
