The Potential of Urban Boarding Schools for the Poor: Evidence from SEED
研究了美国唯一面向贫困学生的城市公立寄宿学校SEED，通过入学抽签发现，就读该校每年使阅读成绩提高0.211个标准差、数学成绩提高0.229个标准差，且效果可能主要由女生驱动。
The SEED schools, which combine a "No Excuses" charter model with a 5-day-a-week boarding program, are America's only urban public boarding schools for the poor. We provide the first causal estimate of the impact of attending SEED schools on academic achievement, with the goal of understanding whether changing a student's environment is an effective strategy to increase achievement among the poor. Using admission lotteries, we show that attending a SEED school increases achievement by 0.211 standard deviation in reading and 0.229 standard deviation in math per year. However, subgroup analyses show that the effects may be driven by female students.
