WCAG 3 applies to web content, apps, tools, publishing, and emerging technologies on the web.</p> <p>We will update this page regularly as work on the WCAG 3 Draft progresses.</p> <h2 id="status-exploratory-draft">Status: Exploratory Draft</h2> <p>The May 2024 <a href="https://www.w3.org/TR/wcag-3.0/">WCAG 3 Working Draft</a> includes <strong>potential</strong> outcomes that we are exploring. The final set of outcomes in WCAG 3 will be different from this draft. Outcomes will be edited, added, combined, and removed.</p> <p>The purpose of this draft is to:</p> <ul> <li>better understand the scope of user needs and how they could be addressed in an accessibility standard,</li> <li>request assistance in identifying gaps, and</li> <li>request assistance locating and conducting research to validate or invalidate the drafted outcomes.</li> </ul> <p>Some of the outcomes are marked as needing research. We are particularly interested in assistance identifying or conducting research to support or refute them.</p> <h3 id="for-your-review">For your review</h3> <p>When reviewing this update, please focus on the Guidelines section. We did not make changes to conformance related sections.</p> <p>Please consider the following questions when reviewing the outcomes in this draft:</p> <ul> <li>What outcomes needed to make web content accessible are missing?</li> <li>What research supports or refutes these outcomes?</li> <li>Are any of these outcomes out of scope for accessibility standards? If so, please explain why.</li> </ul> <p>To provide input, please file GitHub issues at: <a href="https://github.com/w3c/wcag3/issues">https://github.com/w3c/wcag3/issues</a><br /> Or, if you are unable to use GitHub, send email to public-agwg-comments@w3.org</p> <p>Please create separate GitHub issues or email messages for each topic (rather than putting multiple topics in a single issue or email).</p> <h3 id="status-of-sections">Status of Sections</h3> <p>Each normative section has a status that 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.</p> <ul> <li><strong>Placeholder:</strong> This content is temporary. It shows the type of content or section to expect. Placeholder text will be replaced. It is hidden by default in the Editor’s draft. No feedback is needed on placeholder content.</li> <li><strong>Exploratory:</strong> The Working Group is exploring what direction to take with this section. This content is not refined; details and definitions may be missing. It is hidden by default in the Editor’s draft. We invite feedback on the proposed direction.</li> <li><strong>Developing:</strong> There is rough agreement on what is needed for this section, although not all high-level concerns have been settled. Details are included, yet they are not all agreed on. We invite general feedback on how understandable, usable, and reasonable the section is generally.</li> <li><strong>Refining:</strong> The Working Group has reach consensus on this section. It is ready for broad public review and experimental adoption. We seek feedback on feasibility and issues with implementations.</li> <li><strong>Mature:</strong> The Working Group thinks this content is ready for the final standard. Feedback should be focused on edge case scenarios the Working Group might not have anticipated.</li> </ul> <p><img src="/WAI/content-images/wcag/dialogs2.svg" alt="" style="float: right; margin-left: 2rem; width: 30%; max-width: 220px" /></p> <p><strong>There are substantial open issues that are still being discussed, particularly about testing and conformance.</strong></p> <!-- ### Review and Comments We welcome 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](https://www.w3.org/TR/wcag-3.0-requirements/). The best way to provide this feedback is by opening new [GitHub issues](https://github.com/w3c/wcag3/issues/new). Alternatively, e-mail public-agwg-comments@w3.org Please put each topic in a separate GitHub issue or e-mail. Additionally, we welcome comments on ways that the Accessibility Guidelines Working Group can better support your review, feedback, and inclusion in the process of creating WCAG 3.

The July 2023 draft has many changes that resulted from public feedback. We plan to publish updated drafts every 3-6 months.</p> <p><strong>WCAG 3 is not expected to be a completed W3C standard for a few more years.</strong></p> <p>The Working Group will focus on creating an initial set of guidelines and outcomes. Then will focus on refining the structure and conformance model. They will provide updated drafts for review throughout this process. Once the conformance approach is more stable, the Group will focus on refining the accessibility requirements (guidelines, outcomes, assertions, and support material). We will then provide material to help those wanting to transition to WCAG 3; for example, mapping between WCAG 2 and 3 requirements.</p> <p>WCAG 3 will not supersede WCAG 2, and WCAG 2 will not be deprecated, for at least several years after WCAG 3 is finalized.</p> <p>We will update this section with more specific timeline information as it is available.</p> <h3 id="wcag-3-name-formerly-silver-project">WCAG 3 Name (formerly “Silver” project)</h3> <p>The name of WCAG 3 is different from WCAG 2:</p> <ul> <li>WCAG <strong>3</strong> is W3C Accessibility Guidelines</li> <li>WCAG <strong>2</strong> is Web Content Accessibility Guidelines</li> </ul> <p>“W3C Accessibility Guidelines (WCAG) 3.0” was chosen:</p> <ul> <li>because of wide-spread familiarity with the “WCAG” acronym</li> <li>to encompass the broader scope beyond “content”</li> </ul> <h3 id="who-develops-wcag-3">Who Develops WCAG 3</h3> <p>The WCAG technical documents are developed by the Accessibility Guidelines Working Group (<a href="https://www.w3.org/WAI/GL/">AG WG</a>) (previously under the Silver Task Force) with the Silver Community Group.
