Debates in education policy draw on different theories about how to raise children's achievement. The "school competition" theory holds that achievement rises when students can choose among competing schools. The "school resources" theory holds that achievement rises with schools' resources per student. The "family…

Policies about reducing class size have been implemented in the US and Europe in the past decades. Only a few studies have discussed the effects of class size at different levels of student achievement, and their findings have been mixed. We employ quantile regression analysis, coupled with instrumental variables, to examine the causal effects of…

Debates in education policy draw on different theories about how to raise children's achievement. The "school competition" theory holds that achievement rises when families can choose among competing schools. The school resource theory holds that achievement rises with school spending and resources that spending can buy. The "family…

This study used a mixed-methods approach to explore the heterogeneity of effectiveness between supplemental educational services (SES) providers in the Chicago Public Schools (CPS). Using surveys of schools and SES providers, and statistical modeling, providers using college graduates and teachers as tutors were found to be more effective than…

In 2007 Georgia instituted a flexibility policy through which school districts enter into performance contracts with the state, receiving waivers from state rules, provisions, and guidelines in exchange for agreeing to meet annual accountability targets. The performance contracts are intended to incentivize innovations that increase achievement…

This paper investigates how the precision and stability of a teacher's value-added estimate relates to the characteristics of the teacher's students. Using a large administrative data set and a variety of teacher value-added estimators, it finds that the stability over time of teacher value-added estimates can depend on the previous achievement…

Class-size reduction (CSR) mandates presuppose that resources provided to reduce class size will have a larger impact on student outcomes than resources that districts can spend as they see fit. I estimate the impact of Florida's statewide CSR policy by comparing the deviations from prior achievement trends in districts that were required to…

This article examines whether performance-driven educational accountability policy enhances or hinders equity. Combining data from state policy surveys, F-33, SASS, and NAEP, the article shows that during the 1990s, the states did not address racial and socioeconomic disparities in school resources and failed to narrow the achievement gaps among…

States' policy approaches to accountability tend to divide between a primary emphasis on input guarantees and a primary emphasis on performance guarantees. In the midst of keen controversies about the impact of high-stakes testing under the No Child Left Behind Act, this article examines separate and joint effects of input-guarantee versus…
