CED implemented the “Peace Games” project, a program for peace and citizenship education in the Putumayo department in Colombia. The Putumayo department is a region of the country where several manifestations of the Colombian armed conflict (guerillas, drug trafficking) are still visible. CED developed a professional development program addressed at teachers for the implementation of Peace Games. This involved the follow up and on-the field support for participant teachers in rural schools. The program impacted 12 rural schools in Putumayo, 77 school teachers, and 111 parents. During the term of the project, which was one academic semester, 84 visits and 103 class observations were done for the project. This project was supported by the National Ministry of Education of Colombia, with funding from the World Bank.
