论文摘要

问题定义:传统上,纽约市的前8名公立学校仅根据专业高中招生考试(SHSAT)中的分数选择了候选人。已知这些分数受到学生的社会经济地位和中学的测试准备的影响,从而在教育管道中产生了巨大的过滤效果。将学生分配到学校的经典机制自然不会解决学校隔离和班级多样性等问题,这些问题多年来一直恶化。包括决策者在内的科学界通过纳入群体特定的配额和比例约束来做出反应,结果混合了。寻找有效且公平的方法来扩大获得一流教育的有效方法的问题尚未解决。 方法论/结果:我们采用一种与大多数既定文献不同的问题进行操作方法,目的是增加经济需求高的学生的机会。使用纽约市教育部(DOE)的数据,我们表明,学生获得的分数分布发生了变化,而DOE将其归类为“弱势群体”(遵循标准遵循主要基于经济因素)。我们将这一转变建模为“偏见”,这是由于低估了处境不利的学生的真正潜力。我们分析了这种偏见对种类匹配市场的影响。我们表明,当他们针对弱势群体平均表现的弱势学生的细分市场时,中央计划的干预措施可以通过奖学金或培训来大大减少偏见的影响。

Problem definition: Traditionally, New York City's top 8 public schools have selected candidates solely based on their scores in the Specialized High School Admissions Test (SHSAT). These scores are known to be impacted by socioeconomic status of students and test preparation received in middle schools, leading to a massive filtering effect in the education pipeline. The classical mechanisms for assigning students to schools do not naturally address problems like school segregation and class diversity, which have worsened over the years. The scientific community, including policymakers, have reacted by incorporating group-specific quotas and proportionality constraints, with mixed results. The problem of finding effective and fair methods for broadening access to top-notch education is still unsolved. Methodology/results: We take an operations approach to the problem different from most established literature, with the goal of increasing opportunities for students with high economic needs. Using data from the Department of Education (DOE) in New York City, we show that there is a shift in the distribution of scores obtained by students that the DOE classifies as "disadvantaged" (following criteria mostly based on economic factors). We model this shift as a "bias" that results from an underestimation of the true potential of disadvantaged students. We analyze the impact this bias has on an assortative matching market. We show that centrally planned interventions can significantly reduce the impact of bias through scholarships or training, when they target the segment of disadvantaged students with average performance.
