We investigate student mobility in a choice-based system that has gone to scale, New Orleans, to gain insight into an underlying improvement mechanism of choice-based reform and its potential equity-related consequences. In contrast to typical analyses of mobility, this study distinguishes incumbent school characteristics that can cause students to search for a new school (“push” factors) from those features that can draw families to a new school (“pull” factors). We find evidence consistent with school performance playing both push and pull roles. However, for low-achieving students, the push of low performance at incumbent schools is stronger than the pull of high performance at potential destinations, implying that low-achieving students are more successful in exiting low-performing schools than they are in finding higher-performing schools to attend.

学校表现的推力和拉力：来自新奥尔良学生流动性的证据


我们调查了新奥尔良基于选择的系统中的学生流动性，该系统已经规模化，以深入了解基于选择的改革的潜在改进机制及其潜在的公平相关后果。与典型的流动性分析相反，本研究区分了可以导致学生寻找新学校的现有学校特征（“推”因素）和可以吸引家庭去新学校的特征（“拉”因素）。我们发现与学校表现一致的证据，既发挥了推力作用，也发挥了拉力作用。然而，对于成绩不佳的学生来说，在现有学校的低成绩的推动力比潜在目的地的高成绩的拉力更大，这意味着成绩差的学生离开成绩差的学校比找到更高的学校更成功。参加的表演学校。
