We have much to learn from systems that have demonstrated continuous improvement, in contexts as varied as Singapore, Chile, Ghana, Slovenia, and England. While each of these countries had very different starting points, progress has been aided by the political will to measure outcomes and learn from results, define a sustainable path for change, and make smart, effective investments.
我们可以从表现出持续改善的体系中学到很多东西，比如新加坡、智利、加纳、斯洛文尼亚和英格兰。这些国家的起点大相径庭，但这些国家拿出了衡量成果、总结经验、提出可持续的变化路径以及进行精明有效投资的政治意愿，极大地推动了教育进步。
