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.
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.

Public Working Drafts
No official W3C working drafts have been published. We are currently working on a version that will become the First Public Working Draft.
- Master Branch in Github - this is the latest version with broad agreement. It is the least complete. Other branches represent proposals in various stages of development.
- Proposal for the minimum viable product for the First Public Working Draft of WCAG3 - the list of what AGWG and Silver agree should be in the First Public Working Draft. T-shirt estimate spreadsheet (in progress)
- Branch with Headings updates to illustrate Jake's proposal - 11 May 2020
- Editor's draft with changes from VF2F meeting - This is based on discussions at the Silver Virtual Face to Face meetings and subsequent Silver meetings.
older versions still needed for reference

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:
- Audio Description draft from AccessU face-to-face (May 2019)
- Pause Stop Hide (from original plain language prototype) is also a midrange difficulty SC, but is very long - First (rough) draft ready
- 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.
- Sensory Characteristics (from original plain language prototype) is midrange difficultly SC - not started
- Timing (example of merging levels) - not started
Drafts of New Content Proposals from Task Forces and Prototypes
from Cognitive Accessibility Task Force (COGA)
- Clear Language - see Clear Language Subgroup
- Enable APIs
from Low Vision Task Force (LVTF)
- Point of Regard - Original - edits added from LVTF | Silver Draft of Point of Regard - Charles Hall
- Text Spacing - Original | Silver Draft of Text Spacing - not started
from Other Sources
- XR Subgroup
- Locate the User - this came from the Information Architecture prototype testing to test the concept of new guidance that is difficult to test using true/false statements (success criteria). It has sample tests and methods. The idea and some text comes from the Design Patterns for Mental Health website. It was inspired by a blog by Dave Swallow - A web of anxiety: accessibility for people with anxiety and panic disorders.

W3C default time zone is US Eastern Time. There are several weeks in the spring and fall when the US changes to daylight saving time before other parts of the world. In that case, the US Eastern Time is used as the base time zone. Check the World Clock Meeting Planner to determine the time in UTC and other timezones.
Please note that the WebEx can call you, so that you do not incur long distance charges (cell minutes may still apply). You can select Call Me from the Audio options and enter the phone number you wish WebEx to call. This also works for international calls.
