This training guide—and its companion; The Gambia’s Handbook on Multi-Grade Teaching—went through a process of development that was uniquely participatory and highly interactive. It was developed under the leadership of project LIRE and the Technical Working Group in The Gambia (TWG). This manual was further enriched with inputs and contributions from education officials and teachers involved in the LIRE multi-grade program. TWG members were drawn from key stakeholders from within and outside the Ministry of Education. Members are seasoned curriculum developers and planners with years of experience in curriculum and materials development.
