Before the 2020-2021 school year, policymakers and parents confronted the uncertain trade-offs implied by the health, educational, and economic consequences of offering instruction remotely, in person, or through a hybrid of the two. Most public schools in the United States chose remote-only instruction, and enrollment fell dramatically (i.e., a…

This study examined whether pre-K benefits persist through the end of first grade and the extent to which persistence differs based on outcome domains, subsequent classroom environments, and key subgroups of children. Data from 2,351 children living in a large and diverse county in Virginia revealed that the initial benefits of pre-K for academic…

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,…

This study was designed to assess the effects of states' adoption of more rigorous standards as part of the current wave of standards-based reform on student achievement using comparative interrupted time series analyses based on state-level NAEP data from 1990 to 2017. Results show that the effects of adopting more rigorous standards on students'…

The public narrative surrounding efforts to improve low-performing K-12 schools in the United States has been notably gloomy. But what is known empirically about whether school improvement works, which policies are most effective, which contexts respond best to intervention, and how long it takes? We meta-analyze 141 estimates from 67 studies of…

This study examines the impacts of two AmeriCorps programs, Minnesota Reading Corps and Wisconsin Reading Corps, where AmeriCorps volunteers provide literacy tutoring to at-risk kindergarten through third-grade (K-3) students utilizing a response-to-intervention framework. This evaluation replicates a prior randomized controlled trial evaluation…

Prior research has shown that English learner (EL) classification is consequential for students; however, less is known about how EL classification affects student outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using a national data set (Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 or…

This study examines growth in language and math skills during the summer before kindergarten; considers variation by family income, race/ethnicity, and dual language learner status; and tests whether summer center-based care sustains preschool gains. Growth in skills slowed during summer for all children, but the patterns varied by domain and…

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…

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'…

This article explores how the associations between student achievement and achievement growth influence our understanding of the role schools play in academic inequality. Using nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), we constructed parallel growth and lagged score…
