Challenges to curriculum planning include limited funding, lack of school facilities, insufficient teaching and learning resources, issues with teaching staff quality and quantity, and poor time management. Specifically, developing countries struggle due to rising student and teacher populations but decreasing education budgets. Schools have shortages of classrooms, libraries, and equipment. There is also limited procurement of instructional materials and resources. Success depends on qualified teachers, but teaching staff can be inadequate. Additionally, administrators and teachers sometimes mismanage learning time.
