This report analyses the progresses made by Cambodia, Colombia, Mongolia and Uganda in the development and piloting of GCED tools, designed within the framework of UNESCO Asia-Pacific Centre of Education for International Understanding (APCEIU)’s and International Bureau of Education (IBE)’s three-year cooperation project, “Global Citizenship Education Curriculum Development and Integration”. Based on the needs identified through the situational analyses carried out during Phase I, the four countries have developed tailored tools to mainstream GCED in their own context and piloted them during Phase II. Through an in-depth analysis of the tools as well as of their piloting processes, this report aims at understanding the extent to which GCED concepts are embedded and integrated into these tools and the way in which these tools contribute to the overall GCED teaching and learning practices in each context. What results from the findings is that the four countries, despite some setbacks due mainly to the strict timeline, have made significant progress in developing innovative strategies to integrate GCED principles into their education policies and practices. Finally, this report concludes with the suggestions for these tools to be effectively implemented during Phase III, particularly for this project, and for any further initiative around GCED areas.
