Some claim that the PISA results are based on too wide a range of factors to be relevant, while others point out the challenges inherent in testing students in various languages and with different cultural backgrounds. Of course, comparing education across countries is not easy, but PISA remains the most useful tool yet developed for policymakers attempting to improve their national education systems.
有些人说PISA的结果基于太广泛的因素组合，这些因素之间缺乏关联，另一些人则认为测试不同语言和文化背景的学生天生具有不合理性。当然，比较国家间的教育决非易事，但PISA仍是目前试图改善国民教育体系的决策者最有用的工具。
