This handbook aspires to engage and involve parents, caregivers and the community to join the mission of developing every learner into a global citizen. To achieve this, parents, caregivers and the community will need to be empowered with the necessary GCED knowledge and skills too. In this handbook, GCED related concepts are introduced, alongside adaptable step-by-step action plans and best practices collected across the Asia-Pacific region to support parents and the community to take action in developing GCED competences in learners.
