Teacher value-added models (VAMs) must isolate teachers' contributions to student achievement to be valid. Well-known VAMs use different specifications, however, leaving policymakers with little clear guidance for constructing a valid model. We examine the sensitivity of teacher value-added estimates under different models based on whether…

This article investigates the use of teacher value-added estimates to assess the distribution of effective teaching across students of varying socioeconomic disadvantage in the presence of classroom composition effects. We examine, via simulations, how accurately commonly used teacher value-added estimators recover the rank correlation between…

One of the modifications of the Elementary and Secondary Education Act (known as the No Child Left Behind Act) gave parents of low-income students in low-performing schools a choice of Supplemental Educational Services (SEdS). SEdS include tutoring or other academic support services offered outside the regular school day, at no charge to students…

Pay for performance plans are spreading across the country due to the Obama administration's $4 billion Race to the Top initiative, which places a high priority on merit pay. Through a program that involved public accountability and bonuses, the state of North Carolina awarded more than $1 billion in school-based performance bonuses for meeting…

By incorporating two theoretical frameworks this study examines how school characteristics shape first-grade reading ability-grouping practices, and how this, in turn, affects students' reading achievement. The author uses the data from the Early Childhood Longitudinal Study and applies the propensity-score method to examine whether first-grade…

The purpose of the current study was to test the efficacy of a supplemental phonological awareness focused intervention delivered by community-based paraeducators with preschool children (M = 4.73 years) in eight Head Start classrooms in the rural Midwest. Participating children were randomly assigned to small groups within classrooms, which were…

This article provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions. The article (a) provides new empirical information about the values of parameters that influence the precision of impact estimates (intraclass correlations and R[superscript 2] values) and…

This article reports the effects of a comprehensive elementary school-based social-emotional and character education program on school-level achievement, absenteeism, and disciplinary outcomes utilizing a matched-pair, cluster-randomized, controlled design. The "Positive Action" Hawai'i trial included 20 racially/ethnically diverse schools (M…

Prior research estimating the effect of Catholic schooling has focused on high school, where evidence suggests a positive effect of Catholic versus public schooling. In this article, we estimate the effect of attending a Catholic elementary school rather than a public school on the math and reading skills of children in kindergarten through fifth…

Expanded instructional time has become increasingly popular as a strategy to improve the academic outcomes of low-skilled students, particularly in the 9th grade. We evaluate the efficacy of a double-period algebra policy initiated in the Chicago Public Schools in 2003. This policy required all students with 8th-grade test scores below the…

This article presents a randomized experiment evaluating a computer-assisted tutoring program. The software program, Alphie's Alley, provides reading tutors with assessment and planning tools and performance support. It provides students with animated presentations and engaging activities. In a yearlong study involving 25 schools using the Success…
