Estimates of school voucher impacts on educational attainment have yet to explore heterogeneities in socioeconomic status among disadvantaged minority students. We theorize reasons for these heterogeneities and then estimate experimentally the differential impacts of voucher offerson college enrollment and graduation rates for minority and non-immigrant students from moderately and severely disadvantaged backgrounds.The findings are obtained from a privately sponsored, lottery-based voucher intervention in New York City that began in 1997. College enrollment and degree attainment as of the fall of 2017 were obtained from the National Student Clearinghouse. We find no significant effects of offers on minority students from severely disadvantaged backgrounds but significant effects of six to eight percentage points on those from moderately disadvantaged households. Similar results are obtained for students born of non-immigrant mothers. Some policy implications are discussed.
Concerns about the breadth of the U.S. income distribution and limited intergenerational mobility have led to a focus on educational achievement gaps by socio-economic status (SES). Using intertemporally linked assessments from NAEP, TIMSS, and PISA, we trace the achievement of U.S. student cohorts born between 1954 and 2001. Achievement gaps between the top and bottom deciles and the top and bottom quartiles of the SES distribution have been large and remarkably constant for a near half century.These unwavering gaps have not been offset by overall improvements in achievement levels, which have risen at age 14 but remained unchanged at age 17 for the most recent quarter century. The long-term failure of major educational policies to alter SES gaps suggests a need to reconsider standard approaches to mitigating disparities
