WCAG 3 Introduction

Introduction

WCAG 3 is currently an incomplete draft. It is intended to develop into a W3C Standard in a few years. The current standard, Web Content Accessibiilty Guidelines (WCAG 2), is introduced in the WCAG 2 Overview.

The WCAG 3 documents explain how to make the web more accessible to people with disabilities. WCAG 3 applies to web content, apps, tools, publishing, and emerging technologies on the web.

This page will be updated regularly as work on the WCAG 3 Draft progresses.

Status: Draft for Review

The first incomplete, unpolished Draft, W3C Accessibility Guidelines (WCAG) 3.0 Working Draft, was published in December 2021. It included:

The latest incomplete, unapproved Editors’ Draft is available.

We received a lot feedback and are using that to rewrite the approach. We will use an interative approach to create WCAG 3, that makes content visible at various states of maturity. Each normative section is given a status. This status indicates how far along in the development process this section is, how ready it is for experimental adoption, and what kind of feedback we are looking for.

We seek input from evaluators, developers, designers, project managers, policy makers, people with disabilities, and others.

We also welcome comments on the goals and parameters in Requirements for WCAG 3.0.

The best way to provide this feedback is by opening new GitHub issues. Alternatively, e-mail public-silver@w3.org

Additionally, we welcome comments on ways that the Accessibility Guidelines Working Group can better support your review, feedback, or inclusion in the process of creating WCAG 3. Please e-mail these to group-ag-chairs@w3.org

WCAG 3 Draft Approach

Some Similar, Some Different

Goals for WCAG 3 include:

WCAG 3 is similar to previous versions in some ways. It has similar:

WCAG 3 is very different from previous versions in some ways. It has:

Structure

This WCAG 3 draft has:

More granular means they are more specific, instead of broad. That generally makes them simpler. It also means there will be more of WCAG 3 outcomes than WCAG 2 success criteria.

WCAG 3 supporting material includes:

Draft Conformance Model

The conformance model is the way to determine and communicate how well a website (or app, tool, etc.) meets WCAG. The conformance model in this draft of WCAG 3 is very different from WCAG 2. It is intended to:

We are reworking the conformance model based on feedback and we encourage additional feedback as we iterate.

Development

Timeline

The First Public Working Draft of WCAG 3.0 was published on 21 January 2021. It is the first of many drafts.

The Working Draft published on 07 December 2021 has minor changes. Many issues are still open, including testing and conformance.

The Working Group will focus on refining the structure and conformance model, and will provide updated drafts for review. Once that is more stable, the Group will focus on developing the accessibility requirements (guidelines, outcomes, and support material). After WCAG 3 is more stable, we will provide material to help those wanting to transition to WCAG 3; for example, mapping between WCAG 2 and 3 requirements.

WCAG 3 is not expected to be a completed W3C standard for a few more years. WCAG 3 will not supersede WCAG 2, and WCAG 2 will not be deprecated, for at least several years after WCAG 3 is finalized.

We will update this section with more specific timeline information as it is available.

WCAG 3 Name (formerly “Silver” project)

The name of WCAG 3 is different from WCAG 2:

“W3C Accessibility Guidelines (WCAG) 3.0” was chosen:

Who Develops WCAG 3

The WCAG technical documents are developed by the Accessibility Guidelines Working Group (AG WG) with the AG WG Silver Task Force and the Silver Community Group. These Groups are part of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI). You can learn about the development process from How WAI Develops Accessibility Standards through the W3C Process: Milestones and Opportunities to Contribute.

We welcome your comments on WCAG 3 Working Drafts. The best way to provide feedback is by opening new GitHub issues. Alternatively, e-mail public-silver@w3.org

Opportunities for contributing more directly to WCAG and other WAI work are introduced in Participating in WAI.
