This article discusses the importance of monitoring education for sustainable development and global citizenship as outlined in Goal 4, Target 7 of the 2030 Agenda for Sustainable Development. While progress has been made in mainstreaming these concepts into education policies, curricula, and teacher training, simply tracking inputs and processes is not sufficient. A more rigorous approach is needed to ensure learners acquire the knowledge and skills aligned with the goals of sustainable development and global citizenship. UNESCO's existing mechanism for monitoring relies on member state reports that often have low response rates and quality, so it requires complementing with other assessment methods focused on learning outcomes.
