Such requirements have actively engaged Human-Computer Interaction (HCI) research community to ensure that IT interfaces can be used on an equal basis by users with disabilities and older users. It is therefore essential that the interface is easy to use and that it meets the expectations and needs of all users. The advancement and diffusion of technology, particularly the Internet, requires providing quality and easily accessible information. These requirements confirm the relevance of the role of the interface as the main element of user interaction with information systems. The development of interfaces that satisfy users with different needs, use their motor and perceptual, cultural and social skills is not a simple task. According to several experts and pioneers in HCI, interfaces must be built respecting the principles of user-centric design, using a high level of use and in compliance with the guidelines of basic accessibility so that all the aspects of a user’s experience (UX) in such environments are considered and covered. We realize that interfaces are still an important research, worth exploring for its potential to create accessible personalized interfaces. That’s the aim of this work when proposing a methodology for assessing dynamic websites accessibility which can be applied throughout or in the end of the development phase. This evaluation is based on an open document made available by the World Wide Web Consortium (W3C) regarding accessibility guidelines, a standard to ensure the long-term growth of the Web through the Web Accessibility Initiative (WAI).porconference object2020-08-18cv-prod-1995512
