The national curriculum plays a critical role in ensuring consistency across education systems, providing a framework for learning objectives and assessment. It establishes a common set of standards that schools must follow, helping to guarantee that all students receive a foundational education that meets national expectations. This uniformity can facilitate the transfer of students between schools and regions. However, critics argue that a rigid national curriculum may stifle local autonomy and innovation in teaching, suggesting a need for a balance between consistency and flexibility to cater to diverse student needs.
