Many aspects of W3C Accessibility Guidelines (WCAG) 3 are in an exploratory phase, and will change substantially. We published an updated WCAG 3 Working Draft on 12 December 2024.
WCAG 3 will have similar fundamental and specific accessibility requirements as WCAG 2. WCAG 3 will have a different structure, different conformance model, and broader scope.
Please share this page as the starting point for official information about WCAG 3 now and in the future. Short link: w3.org/WAI/wcag3
Page Contents IntroductionW3C Accessibility Guidelines (WCAG) 3 is currently an incomplete draft. WCAG 3 is intended to develop into a W3C Standard in a few years. The current standard, Web Content Accessibility Guidelines (WCAG 2), is introduced in the WCAG 2 Overview.
The WCAG 3 documents will 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.
We will update this page regularly as work on the WCAG 3 Draft progresses.
Status: In-progress draftsIn December 2024, we published updated drafts:
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.
For more information on these status indicators, see the Explainer section Current Process for Creating WCAG 3.0.
For your reviewIn this WCAG 3 Working Draft, there are four updated sections that we would particularly like feedback on. The first three sections are guidelines:
For these sections, does the information under ‘Which foundational requirements apply?’ make the guidelines easier to understand and use?
The other section we would like feedback on is:
This section explains the conformance approach we are considering for WCAG 3. There are still many details to be worked out. Do you have constructive comments about this proposed conformance approach for WCAG 3?
Research neededSome of the guidelines and requirements are marked with “Needs additional research”. We are particularly interested in assistance identifying or conducting research to support or refute them.

Please create separate GitHub issues or email messages for each topic, rather than putting multiple topics in a single issue or email.
WCAG 3 Draft approach Some similar, some differentGoals 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:
The name of WCAG 3 is different from WCAG 2:
“W3C Accessibility Guidelines (WCAG) 3.0” was chosen:
For a description of the structure of the December 2024 WCAG 3 Working Draft, see the Explainer section WCAG 3.0 Structure.
Conformance approachThe conformance model is the way to determine and communicate how well content, a website, an app, etc. meets WCAG.
The conformance model in WCAG 3 will be very different from WCAG 2. It is intended to:
Developing and vetting the conformance model is a large portion of the work AG needs to complete over the next few years.
The December 2024 publications have updated information in:
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.
The Accessibility Guidelines Working Group (AG WG) has created an initial set of guidelines. In the first part of 2025, AG WG will focus on developing two or three guidelines to Refining or Mature status. We will use that experience to develop a projected timeline for WCAG 3. We expect the timeline to be available by September 2025.
For information on current timelines and activities, see WCAG 3 Publication Plan.
We will update this section with more specific timeline information as it is available.
Who develops WCAG 3The WCAG technical documents are developed by the Accessibility Guidelines Working Group (AG WG) (previously under the Silver Task Force) with 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.
