中文摘要
摘要 我们表明，教师的增值（VA）取决于其前任教师的 VA。为此，我们使用北卡罗来纳州的行政数据发现，上一年级教师平均 VA 每增加一个标准差，会导致该教师的 VA 下降 0.08σ。控制前任教师的分配可以消除这一偏误。在一项释放 VA 分布底部 5% 教师的基准政策下，若使用传统技术，32% 的教师将被错误解聘。我们的研究结果凸显了将教育生产的动态特征纳入教师质量估计的重要性。
Abstract
Abstract We show that teachers’ value added (VA) depends on the VA of the teachers who preceded them. To do so, we use administrative data from North Carolina and find that a one-standard deviation increase in last grade’s mean teacher VA causes a 0.08σ decrease in teacher VA. Controlling for prior teacher assignment eliminates this bias. Under a benchmark policy that releases teachers in the bottom 5% of the VA distribution, 32% of teachers are incorrectly released using traditional techniques. Our results highlight the importance of incorporating dynamic features of education production into the estimation of teacher quality.
