About
The Global Citizenship Schools Trustmark is a support and certification initiative for whole-school global citizenship education (GCED). It gives schools a structured framework to develop global competence across the curriculum and to engage the wider community in that work.
Schools build and grow their GCED practice using the Trustmark's quality standards, frameworks, and tools, and are then assessed against GCF 1002:2025, the first independent quality standard for whole-school GCED certification.
The Trustmark helps schools organize and connect their efforts across six dimensions: governance and leadership, teacher and staff capacity, teaching and learning, student agency, partnerships, and review. It is curriculum-agnostic. Schools at any stage of their GCED journey, and within any curriculum framework, are eligible to apply.
The Global Citizenship Schools Trustmark support is offered through Global Citizenship School Services, Germany. The Certification is offered by the Global Citizenship Foundation.

The Global Citizenship Schools Trustmark is open to schools worldwide at any stage of their global citizenship education journey. Any formal school or educational institution serving learners from early years through to the end of secondary education is eligible, including independent schools, international schools, state-funded schools, and schools operating within national or international curriculum frameworks.
The Trustmark is curriculum agnostic. There is no requirement to follow a specific curriculum or programme model, and no minimum level of existing GCED practice is required to apply. Schools beginning to formalise this work and schools with established practice are equally eligible.
The certification process is conducted in English. A working proficiency of B2 level or above (CEFR) is required for the school coordinator and staff directly involved in documentation and assessment.
Participation in the 2026-27 Founding Cohort is by invitation following an expression of interest. The cohort is capped at 25 schools. Selection will reflect curricular and geographic diversity.
