Tutoring ranks among the most versatile and potentially transformative educational tools available. Dozens of randomized experiments have evaluated preK-12 tutoring programs, varying widely in approaches, contexts, and costs. This article presents results from a systematic review and meta-analysis of tutoring field experiments. We develop a…

New York City's Pre-K for All (PKA) is the nation's largest universal early childhood initiative, serving over 64,000 four-year-olds annually. Stemming from the program's choice architecture as well as the city's stark residential segregation, PKA programs are extremely segregated by child race/ethnicity. Our current study explores the complex…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

Kindergarten teachers face the challenge of integrating contemporary assessment practices with play-based pedagogy. The current study addresses this challenge by presenting a kindergarten assessment framework rooted in theory and current classroom practices, based on teacher interview and observational data collected in 20 kindergarten classrooms.…

Drawing on a 3-year interpretive study that followed a cohort of children from prekindergarten to Grade 1, this article presents results of a multiple case study, which demonstrated that although two children had the same teachers, classmates, and curricula over 3 years, their experiences in the three successive mathematics classrooms were quite…

Parental engagement is central to Head Start's two-generation mission. Drawing on research linking teacher-child racial/ethnic match to educational outcomes, the present study explores whether teacher-child match increases parental involvement in Head Start activities designed to support children and families. Using data from the 2006 and 2009…

We used multilevel analysis to examine the predictive validity of scores from the Framework for Teaching (FFT), the observation measure used most often to evaluate teachers' instruction. We investigated how well 81 kindergarten teachers' FFT scores for eight reading and eight mathematics lessons observed throughout the year predicted students'…

The present study examined the relations between teacher-child interactions, teachers' Spanish use, classroom linguistic composition, and the school readiness skills of low-income, Latinx, Spanish-speaking dual language learners (DLLs), controlling for home and teacher background characteristics, with a national probability sample of Head Start…

This study drew data from a randomized trial of a statewide prekindergarten program in Tennessee and presents new evidence on the impacts of preK on third-grade achievement using administrative data on children's neighborhood environments. Results indicate that preK had no measurable impact on children's third-grade math achievement regardless of…

Most accountability policies monitor Head Start quality at the center level by selecting a subset of classrooms within a center to represent quality. This study explores variation in classroom quality in Head Start and implications for accountability systems and children's well-being. We find that one third to one half of the variation in quality…
