This article on web accessibility illustrates a study on the accessibility quality index of government services websites related to 10 countries after its implementation of web-accessible guidelines. This assessment is performed to analyze the website's compliance with the latest WCAG 2.0 guidelines and ARIA rules published by the World Wide Web Consortium (W3C). The intent of this research is to determine whether the implemented guidelines are reflecting and usable as per norms or not. Research also includes quality index differences that are stats how different tools are analyzing the same website and differ on quality issues. The WCAG 2.0 guidelines support web accessibility implementation, and we are referring to the Website Accessibility Conformance Evaluation Methodology (WCAG-EM) to refer to how easily disabled people can access websites. It is observed that the majority of the websites do not achieve an acceptable level of compliance. From this research, we conclude that most of the evaluation tools are different in providing exact accessibility issues present on a specific website, and this caters to final quality index differentiation. This research was specifically performed on government services-related websites because the majority of disabled people are using government services for day-to-day operations such as banking, education, policies, registrations, taxes. With multiple manual testing iterations, it was found that several non-compliance errors are present on these websites. Changing the defect count of every tool on the same website on two different occasions results in more work planning for developers; with this observation, there is a significant amount of work that needs to be done in this area where tools need to be more robust w.r.t accessibility issues.
