Many educators and leaders in international schools around the globe recognize the value and urgency of global citizenship education (GCE) and the need to empower PreK-12 students to engage in authentic community engagement and active local and global citizenship. To this end, many educators use the United Nations Sustainable Development Goals (SDGs) to help students understand the most pressing issues of our time and to pursue individual and collective pathways to sustainability. Educators also may prioritize social and emotional learning (SEL); diversity, equity, inclusion, and belonging (DEIB); and service learning or community engagement to offer students opportunities to think, learn, and act as informed and reflective citizens. There is a growing awareness among international educators that this approach to educating students is foundational and critical for engagement, learning, and the transfer of knowledge and skills to address practical and identified needs in our local and global communities. As schools employ a whole-school blueprint for active global citizenship, they develop a program and culture that equips students to think in a long-term way about a positive and sustainable future.
