The Silver Task Force is part of the Accessibility Guidelines Working Group of the W3C. The Silver Task Force and the W3C Silver Community Group are performing the preliminary work for the successor to the Web Content Accessibility Guidelines (WCAG) 2. The guidelines will be named W3C Accessibility Guidelines (WCAG) 3.0 which reflects the anticipated broader scope beyond web content, but preserves the familiar acronym of WCAG.

The W3C Accessibility Guidelines (WCAG) 3.0 First Public Working Draft (FPWD) has been published. The is an early draft and is the first of many drafts. The document is not expected to become a W3C Recommendation for a few more years. It is not ready to be implemented yet, as we expect many changes from public feedback and continuing work.

Anyone who would like to participate should read the Welcome to Silver quick-start guide.

What is Silver?

The objective of the Silver Task Force is to perform preliminary research and development for a successor to the Web Content Accessibility Guidelines (WCAG). Code-named "Silver", these guidelines will address the process of making content and functionality accessible to people with disabilities, including the roles of content authoring, user agent support, and authoring tool support. These guidelines will provide a base for continued evolution of accessibility standards.

The Silver project now has an official name. The work will be called W3C Accessibility Guidelines (WCAG) 3.0.

Silver Task Force and Community Group is currently writing the draft for the First Public Working Draft of WCAG 3. The current work is available for reading below.

Participation in the Silver Community Group is open to the public. Interested people can join the the W3C Silver Community Group to be placed on the mailing list and join conference calls. See the Participation Options and the meeting section below for more information on participation. See Welcome to Silver for those who are starting to work on Silver.

Current Work

September 2021 - The group is preparing to publish the Q3 2021 Working Draft. The new material in the working draft will include:

  • User Generated Content Conformance section and glossary definition. This improves the accessibility of user generated content by requiring platforms hosting user generated content to:
    • identify the user generated content,
    • identify the steps taken to improve accessibility of user generated content, and
    • meet new outcomes for third party content specific to guidelines (for example, provide a mechanism for users to enter alternative text for images). The example of the new outcome was not approved by AGWG for publishing, but can be viewed in the editors draft.
    • Platforms that meet these requirements can claim conformance for user generated content.
  • Reduce the ambiguity in testing with revised tabs and content sections in Methods and Tests. This is the result of joint work with the Accessible Conformance Testing (ACT) Task Force. The complete example is Decorative Images. All the existing Methods are moving to the new format, but the groups responsible for the content have not had the opportunity yet to update the material, so other Methods will have "To be done" sections. We expect it to be completed in a future draft.
  • WCAG3 Explainer first draft. This moves much of the explanatory material from WCAG3 into a separate document to improve usability.
  • Error Prevention - new guideline that illustrates a migration of WCAG 2.1 success criterion based on analysis of user needs. This was not approved by AGWG for publishing in a Working Draft, but can be viewed in the Editor's Draft.
  • [ New Methods for Text Alternatives]. This was not approved for publishing in a Working Draft, but can be viewed in the Editor's Draft.

The group has begun work on the next draft and plans to refine the prior topics and address these additional topics:

A Project Plan for Conformance is comprehensive plan with milestones to address the broad topic of Conformance.

WCAG to Silver Migration

Drafts of Other WCAG success criteria to migrate to Silver

We are migrating a few current WCAG 2.1 success criteria to Silver to test our process. See the SubGroups section above for details of active work. Other drafts of the migrated success criteria under development that do not have currently active work are:

  1. Audio Description draft from AccessU face-to-face (May 2019)
  2. Pause Stop Hide (from original plain language prototype) is also a midrange difficulty SC, but is very long - First (rough) draft ready
  3. Language of Environment - adapting 3.1.1 Language of Page - sketched out showing how Methods could be written for user agents, authoring tools, and emerging technologies.
  4. Sensory Characteristics (from original plain language prototype) is midrange difficultly SC - not started
  5. Timing (example of merging levels) - not started
