Authoring Tool Accessibility Guidelines (ATAG) Overview

Authoring Tools and ATAG

Authoring tools are software and services that “authors” (web developers, designers, writers, etc.) use to produce web content (static web pages, dynamic web applications, etc.). Examples of authoring tools are listed below under “Who ATAG is for”.

Authoring Tool Accessibility Guidelines (ATAG) explains how to:

ATAG is part of a series of accessibility guidelines, including Web Content Accessibility Guidelines (WCAG) and User Agent Accessibility Guidelines (UAAG). Essential Components of Web Accessibility explains the relationship between the different guidelines.

ATAG is relevant today, as it is technology agnostic. ATAG was published in 2015 and references WCAG 2.0. We encourage you to use the latest version of WCAG 2.

Who ATAG is for

ATAG and supporting resources are also intended to meet the needs of many different audiences, including policy makers, managers, and others. For example:

ATAG at a Glance provides a short summary of the accessibility principles and guidelines in ATAG.

ATAG is organized in layers:

ATAG 2.0 is a W3C Recommendation, which is a technical standard.

Implementing ATAG 2.0 is a supporting informative document that helps readers understand and use ATAG. Implementing ATAG provides the rationale for each guideline. For each success criterion, it provides explanation of the intent of the success criteria, examples, and links to resources.

ATAG Report Tool

The ATAG Report Tool helps evaluators report on the accessibility of authoring tools. It guides you through the ATAG requirements, lets you record your evaluation results for each requirement, and generates a report of the authoring tool’s ATAG conformance.


ATAG 2.0 is available as an Authorized W3C Translation in Chinese, Simplified: 无障碍创作工具指南(ATAG) 2.0.

Who developed ATAG

ATAG was developed by the Authoring Tool Accessibility Guidelines Working Group (ATAG WG) as part of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI).

Opportunities for contributing to WAI work is explained in Participating in WAI.
