This practical guide for higher education institutions highlights why the role of Inclusion Officer is essential for promoting diversity, equity and accessibility, particularly in the context of international mobility programmes such as the Erasmus+ programme. With insights from interviews, case studies and practical advice, it shows how Inclusion Officers can help universities address systemic barriers, support underrepresented groups and embed inclusive practices into policies, student services and internationalisation strategies. The guide was developed in cooperation with the Academic Cooperation Association (ACA).
