ABSTRACT We study how the introduction of school accountability affects teacher mobility and sorting. We exploit that lower-secondary schools in Oslo became formally accountable to the school district authority for student achievement in 2003 and that the ranking of these schools, based on a value-added measure, became public information in 2005. Using a double and a triple difference estimator, we find substantially increased teacher mobility after the reform. Most teachers who changed their jobs due to the reform left the profession. Nevertheless, leaving teachers were replaced by other high-ability teachers, yielding a positive sorting effect after the second part of the reform.

学校问责制如何影响教师的流动性和教师排序

摘要我们研究学校问责制的引入如何影响教师的流动性和排序。我们利用奥斯陆的初中学校在2003年正式向学区管理局负责学生的成就，而这些学校的排名基于增值方法，在2005年成为了公共信息。差异估算器，我们发现改革后教师流动性大大提高。由于改革而更换工作的大多数教师都离开了该行业。尽管如此，在第二部分改革之后，离职教师被其他高素质的教师所取代，产生了积极的分类效果。
