===Evaluation and Repair Tools Working Group (ERT WG)===
The Evaluation and Repair Tools Working Group develops technical specifications that support the accessibility evaluation and repair of Web sites. It also maintains a database of tools for evaluating Web sites and for making them more accessible ("repair", "retrofitting").
The working group consists mainly of developers of such tools and researchers.
Current work focuses on
* '''Evaluation and Report Language (EARL)''': a language for expressing evaluation reports in a machine-readable way<ref>{{cite web|url=http://www.w3.org/TR/EARL10-Schema/ |title=Evaluation and Report Language 1.0 Schema |publisher=W3.org |access-date=28 July 2013}}</ref><ref>Evaluation and Report Language 1.0 Guide</ref>
