The preparation of teachers, and to some degree, teacher educators in the majority of countries around the world, has traditionally focused on developing understandings, skills, and attitudes appropriate for teaching in local schools. Yet the importance of global competence and intercultural understanding has never been greater. As the world is increasingly faced with expanding challenges such as increased migration due to, among other things, war, famine, climate change and global inequality, there is a demand to recognize the relevance of global competency and to educate young people to be better local and global citizens. This requires teachers and teacher educators to possess a global mindset and take a more active role in fostering that mindset in their classrooms. Moreover, in an ever-changing world, we propose that while our values may evolve, there is a critical need to ensure a greater understanding of the "other". This understanding is increasingly urgent as the interests and opinions of members of societies become more divisive, where deeply held beliefs are more polarized and polarizing (Council of Europe, 2016; UNESCO, 2021).Educating global citizens is likewise part of the Sustainable Development Goals (SDGs) agenda, which emphasizes this among other vital issues (Leite, 2022). However, while countries work to achieve the SDGs, it is necessary to incorporate further education on global citizenship into national curricula by 2030. The impetus for the SDGs is partly a deeper understanding of our interconnectedness as global citizens and a more significant "appreciation of cultural diversity and culture's contribution to sustainable development" (Chiba et al., 2021, p. 1). We believe that educating for global citizenship requires awareness and action consistent with a broad understanding of humanity, the planet, and the impact of our decisions linked to our interconnectedness. Further, we agree with Chiba and colleagues (2021) that education is "integral to the achievement of the SDGs" (p. 1). In our view, such education should distinctly focus on global citizenship.Against this background, together with the lessons learned from the multi-year Global Awareness in Teacher Education (Open GATE) collaborative project between Oslo Metropolitan University (OsloMet) and George Mason University (GMU/Mason), this forum piece attempts to draw some insights on educating global citizens. The project aimed to make the curriculum more reflective of international and global dimensions while ensuring we have more internationally competent teachers and researchers. In the project, we aimed to achieve these goals through transformed courses, opportunities for study abroad, and other formal (including research) and informal experiences for both staff and students and in collaboration with practitioners (schools and local
