Conformance evaluation determines how well web pages or applications meet accessibility standards. W3C’s Website Accessibility Conformance Evaluation Methodology (WCAG-EM) is an approach for determining conformance to Web Content Accessibility Guidelines (WCAG).
- WCAG-EM Overview: Website Accessibility Conformance Evaluation Methodology
- A short page with basic information to get you started. We suggest you read it before going to the full WCAG-EM document.
- WCAG-EM Report Tool: Website Accessibility Evaluation Report Generator
- Helps you generate evaluation reports according to WCAG-EM. It does not do the checking for you. It helps you follow the steps of WCAG-EM and it generates a report from the input you provide.
- Template for Web Accessibility Evaluation Reports
- Suggests information to include in a report.
- ATAG Report Tool
- Helps you generate a report on how a tool meets Authoring Tool Accessibility Guidelines (ATAG). Authoring tools are software and services used to create web content – such as content management systems (CMS) and what-you-see-is-what-you-get (WYSIWYG) HTML editors.
- Accessibility Conformance Testing (ACT) Rules
- Describe how to test conformance of accessibility standards such as WCAG and WAI-ARIA. ACT Rules are primarily used by developers of test tools and methodologies. Accessibility testers may find some rules helpful for evaluating edge cases consistently.
Specifications for expressing test results (EARL) and for writing accessibility test rules (Accessibility Conformance Testing (ACT) Rules Format) are introduced in Evaluation Standards Overview.

|Often you'll want to do conformance evaluation:
||Icons for each stage: open box with a check mark; round "i"; magnifying glass on a computer; and shopping trolley.|
||All icons are integrated in a skyrocket icon. A document with the list of accessibility issues.|
|To do effective conformance evaluation, you need expertise in:
||Icons are shown in turn: conformation evaluation words; award ribbon; paint brush and coding icon; assistive technologies icons; and finally people figures.|
|You'll probably also want to use evaluation tools to be more efficient.||A tool box with a gauge moving up.|
|"WCAG-EM", the "Website Accessibility Conformance Evaluation Methodology", provides a structure for your evaluation process.||WCAG-EM, Website Accessibility Conformance Evaluation Methodology. A magnifying glass with the word accessibility.|
|It describes a process to:
||Text boxes load one after the other: define scope; explore assets; select sample; evaluate sample; and report findings.|
|WCAG-EM also recommends involving real users with disabilities during evaluation, to help you address the real-life experience of your website users.||A person in front of a computer displaying a website. Passes and fails are marked.|
|The open source WCAG-EM Report Tool helps you follow the methodology, record the outcomes, and download a report of your evaluation.||WCAG-EM Report Tool. A progress bar shows the various stages of the evaluation methodology. A record document is displayed in the computer screen and downloaded.|
|Web accessibility: essential for some, useful for all.||Icons around a computer: hand; eye; brain; ear; and mouth with sound waves.|
