An EU Project


Project Results

Accessibility Conformance Testing (ACT) Rules
Includes writing, reviewing, implementing, and validating “Accessibility Conformance Testing (ACT) Rules”. About 55 rules were developed through the project so far, with another 15 to follow this year. This is the result of project deliverables D1.1, D1.2, and D1.3, which are continually developed through the W3C ACT Rules Community Group (previously Auto-WCAG Community Group, which has been renamed).
Prototype large-scale monitoring
Includes open source tool to visualize and compare accessibility test results gathered from different sources, including conformance evaluation reports and accessibility statements. It uses the Open Format for Accessibility Test Results developed by the project as the backbone for open linked data on accessibility.
Norwegian national observatory
Includes running and documenting Pilot Monitoring in accordance with the EU Web Accessibility Directive (WAD), as well as documenting the local WCAG Interpretion and ACT Rules mappings. These reports provide practical insights on an example national monitoring initiative with many key take-aways for the project and beyond.
Portuguese national observatory
Includes processing test results from multiple tools that provide output in the open format developed by the project (see corresponding project deliverable listed below). These tools include the open source engines from Siteimprove, Deque, and University of Lisbon developed through the project. These implement ACT Rules to provide consistent results.
Updated WCAG-EM Report Tool
Includes all the Success Criteria from WCAG 2.0 and 2.1, as well as user-interface improvements to support the selection between these two standards. This version also includes a new “Import” functionality to allow importing of test results, for example from automated testing tools. Further improvements are currently in planning.
Developing an Accessibility Statement
Includes guidance on how to develop accessibility statements for websites, mobile applications, and other digital content, as well as a free and open source accessibility statements generator tool. More information in the blog post How to Create Accessibility Statements.
Open Format for Accessibility Test Results
Includes the definition of an open data format to express accessibility test results. It is a JSON-LD 1.0 serialization of the EARL 1.0 Schema, and is implemented by the open source Alfa and aXe Reporter testing engines.

About the Project

WAI-Tools, Advanced Decision Support Tools for Scalable Web Accessibility Assessments, was an Innovation Action project, co-funded by the European Commission (EC) under the Horizon 2020 program (Grant Agreement 780057). The project started on 1 November 2017 for a duration of three years. WAI-Tools drove web accessibility evaluation and repair through:

WAI-Tools achieved this by carrying out key efforts in the vendor-neutral environment of the World Wide Web Consortium (W3C). WAI-Tools drew together key expertise from industry, public bodies, and research to develop common understanding of web accessibility requirements.
