School Efficiency and Student Sub-groups: Is a Good School Good for Everyone?

State and federal accountability reforms are putting considerable pressure on schools to increase the achievement of historically low-performing groups of students and to close test score gaps. In this article, we exploit the differences among the large number of elementary schools in New York City to examine how much schools vary in the efficiency of the education they provide to subgroups. In addition, we examine the extent to which observable school characteristics can account for the variation that exists. We find that New York City elementary schools vary in how well they educate poor students compared to nonpoor students and Asian and White students compared to Black and Hispanic students. The disparities in school efficiency measures between boys and girls are lower than for the other subgroups. There is no conclusive evidence about which school resources and characteristics are associated with more or less efficient education across all subgroups.
