ATAG 2.0 is now w3c recommendation

Authoring Tools Accessibility Guidelines (ATAG) 2.0 is now recommended by W3C since 24 September 2015. This document has been produced as part of the W3C Web Accessibility Initiative (WAI). The goals of the AUWG are discussed in the Working Group charter.

What is ATAG 2.0?

The Authoring Tool Accessibility Guidelines (ATAG) 2.0 provides guidelines for designing web content authoring tools that are both more accessible to authors with disabilities (Part A) and designed to enable, support, and promote the production of more accessible web content by all authors (Part B).

Structure of ATAG2.0


ATAG 2.0 is divided into two parts, each reflecting a key aspect of accessibility with respect to authoring tools. Part A relates to the accessibility of authoring tool user interfaces to authors with disabilities. Part B relates to support by authoring tools for the creation, by any author (not just those with disabilities), of web content that is more accessible to end users with disabilities. Both parts include normative “Conformance Applicability Notes” that apply to all of the success criteria within that part.


Under each part are several high-level principles that organize the guidelines.


Under the principles are guidelines. The guidelines provide the basic goals that authoring tool developers should work toward in order to make authoring tools more accessible to both authors and end users of web content with different disabilities. The guidelines are not testable, but provide the framework and overall objectives to help authoring tool developers understand the success criteria. Each guideline includes a brief rationale for why the guideline was included.

Success Criteria

For each guideline, testable success criteria are provided to allow ATAG 2.0 to be used where requirements and conformance testing are necessary, such as in design specification, purchasing, regulation, and contractual agreements. In order to meet the needs of different groups and different situations, multiple levels of full and partial conformance are defined.
