This study uses the metafrontier Malmquist-Luenberger index to measure changes in the productivity of 4587 schools in the Colombian education system. Public and private schools are differentiated and all the schools participated in the Saber 11 standardized test between 2014 and 2017 in the subjects of mathematics, reading, sciences, social and citizen sciences and English. This methodology is appropriate to measure productivity while using good and bad outputs in the educational context. The general results indicate deterioration in both sectors; this behavior is due to the change in best practices and the change in efficiency. Large gaps are also found between departments.

本研究使用 metafrontier Malmquist-Luenberger 指数来衡量哥伦比亚教育系统中 4587 所学校的生产力变化。公立和私立学校是有区别的，所有学校在 2014 年至 2017 年期间参加了数学、阅读、科学、社会和公民科学以及英语科目的 Sabre 11 标准化考试。这种方法适用于衡量生产力，同时在教育环境中使用好的和坏的输出。总体结果表明这两个部门都在恶化；这种行为是由于最佳实践的变化和效率的变化。部门之间的差距也很大。
