|The recent growth of the digitalisation of education has increased the importance of digital accessibility. In higher education, faculty members and administrative staff are the main content creators who are responsible for creating and publishing digital content for both students and university staff. Literature shows that these content creators do not have the necessary knowledge to create accessible digital content. At the same time, there is an abundance of information available online about how to create accessible digital content. However, due to the lack of time, the content creators are often not able to find the necessary information for helping them with the accessibility task they have at hand. In this study we have adopted a human-centred approach to develop an online prototype aiming at assisting content creators to create accessible content where target users have been involved in the iterative design, development, and evaluation process. A summative evaluation was also conducted with a mixed-method approach, combining observation, survey, semi-structured interview, and document inspection. The results show that the online guide is helpful for faculty members and administrative staff to improve the accessibility of their digital content. Some usability issues have been discovered and additional features and content have also been suggested by the participants, which will be the focus of future work.
