This study examines 4 years of small school reform in Chicago, focusing on schools formed by converting large traditional high schools into small autonomous ones. Analyzing systemwide survey and outcome data, the authors assess the assumptions embedded in the reform’s theory of change. They find that these schools are characterized by more collegial and committed teacher contexts and more academically and personally supportive student contexts. There is some evidence of decreased dropout rates and increased graduation rates for the first cohort of students but not for the second cohort. The authors do not find stronger instruction, nor do they find student achievement has improved. They discuss implications for reformers and policy makers who are interested in small schools in particular and high school reform in general.

Policymakers are implementing reforms with the assumption that students do better when attending high-achieving schools. In this article, we use longitudinal data from Chicago Public Schools to test that assumption. We find that the effects of attending a higher performing school depend on the school's performance level. At elite public schools with admission criteria, there are no academic benefits-test scores are not better, grades are lower-but students report better environments. In contrast, forgoing a very low-performing school for a nonselective school with high test scores and graduation rates improves a range of academic and nonacademic outcomes.

We investigate whether elite Chicago public high schools differentially benefit high-achieving students from more and less affluent neighborhoods. Chicago’s place-based affirmative action policy allocates seats based on achievement and neighborhood socioeconomic status (SES). Using regression discontinuity design (RDD), we find that these schools do not raise test scores overall, but students are generally more positive about their high school experiences. For students from low-SES neighborhoods, we estimate negative effects on grades and the probability of attending a selective college. We present suggestive evidence that these findings for students from low-SES neighborhoods are driven by the negative effect of relative achievement ranking. (JEL H75, I21, I24, I28, R23)
