A few weeks ago, the MOOCAP project published the first of a set of Open Educational Resources (OERs) on accessibility. Our first OER introduced the concept of accessibility. Our second OER is about a related concept: conformance testing. This new resource consists of a short text in Microsoft Word format and a video on YouTube. The focus is on testing conformance against the Web Content Accessibility Guidelines (WCAG) 2.0, which is the de facto standard for web accessibility. Both the text document and the video are available under a Creative Commons licence.
