Individuals involved in curriculum implementation include teachers, students, administrators, education officers, curriculum developers, academics, parents, politicians, and citizens. Teachers play a central role as they influence student learning and are knowledgeable about curriculum content and pedagogy. An effective implementation requires teachers to understand the philosophy behind the program, familiarize themselves with the content, learn new pedagogical methods, and know the various components like assessment policies. Professional development is important for teachers to successfully carry out any curriculum changes.
