This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The estimated effects of eighth grade reclassification on 9th, 10th, and 11th grade ELA test scores were statistically insignificant, and I can rule out negative effects less than −0.17 SDs and positive effects larger than 0.09 SDs. The negative effect on SAT reading was fairly large, with a confidence interval of −0.27 SDs to 0.05 SDs. Estimates for on-track status in 10th and 11th grades were positive but imprecise.

英语学习者重分类对高中阅读和学术进步的影响

这项研究估计了八年级英语学习者（EL）的重新分类对高中英语语言艺术（ELA）标准化考试成绩，SAT（学术能力测验）阅读以及就读于研究生状态的因果影响。我将回归不连续性设计应用于来自加利福尼亚大区的丰富行政数据。八年级重新分类对9年级，10年级和11年级ELA测试成绩的估计影响在统计学上不显着，我可以排除小于-0.17 SD的负面影响和大于0.09 SD的正面影响。对SAT读数的负面影响相当大，置信区间为-0.27 SDs至0.05 SDs。对10年级和11年级的就读状态的估计是肯定的，但不准确。
