The document discusses the curriculum development system (CDS) and its goals of achieving unity, continuity, and quality in a school's curriculum. The CDS is a four-stage process that includes conceptualizing, operationalizing, and institutionalizing to establish a coordinated, coherent curriculum that is planned, developed, and controlled. This ensures all staff are working towards common learning outcomes, the curriculum is not disrupted by changes in leadership, and high quality is maintained in developing students.
