Today, web technologies have an important role for both individuals and institutions to present information and their services. Since there are a great number of public services including accessing to information through websites, accessibility of them is essential in order to ensure equality of opportunity for people with disabilities. This study, which was designed as a descriptive one, was conducted in order to evaluate the accessibility features of university websites, which have an important place among the public institutions, in terms farkındalıof arrangements for users with visual and hearing impairments. To assess the accessibility level of websites of 179 universities in Turkey, this study employed an evaluation checklist including 20 checkpoints which had been developed in accordance with “Web Content Accessibility Guidelines (WCAG) 2.0”. The results obtained by the accessibility evaluation of university websites indicate that no website reached an acceptable accessibility level. The study discovered that there are a number of accessibility errors/drawbacks including in violation of presenting text content with the screen readers, providing text alternatives for prerecorded audio and video content, and providing sign language interpretation for prerecorded audio contents in video media. However, on the other side, there are some good practices of accessibility on most of the university websites including the visual presentation of text and images of text in an acceptable minimum contrast rate, using colors which could be perceived/seen by color-blind users, and providing users with control mechanism to pause or stop the audio or video content and to control audio volume. The results of this study could shed light on the fact that university websites are not accessible to all users. In this way, this study could help to increase awareness of the accessibility of university websites and to make changes in order to enhance web accessibility.
