In this research, we propose a methodology for evaluating web accessibility with respect to disabled users, especially the vision-impaired and the hearing-impaired. Two stages are involved in our approach. In the first stage, we adopt barriers proposed by the Barrier Walkthrough method to classify possible barriers for each group of users on a web page. In addition, this method proposes checkpoints of WCAG (Web Content Accessibility Guidelines) as barrier causes. All barriers found at this stage would be transformed into the relevant checkpoints. In the second stage, the severity of barriers is assessed by analyzing violated checkpoints. Our formula will also calculate accessibility value from the violated checkpoints. The result of our approach can identify whether the evaluated web pages are suitable for different groups of the disabled.
