On December 11, 2008, the W3C published the Web Content Accessibility Guidelines 2.0 as the new W3C recommendation. WCAG 2.0 aims to be more flexible and does not rely on a specific technology. Moreover W3C/WAI claims that WCAG 2.0 has been designed to be testable as to respond to multiple demands from stakeholders. However, few implementations have been completed yet providing enough feedback about WCAG 2.0 conformance systems over a long period. This paper will discuss the need for a methodology to ensure conformance to WCAG 2.0 that takes the new constraints of this standard into account. It will propose a process for developing this assessment methodology according to specific requirements. It identifies several steps that proved to be essential towards operational results. Finally, it discusses the possible benefits of such a methodology.
