The COVID-19 pandemic posed a significant problem for K-12 education. To prevent the spread of the virus, the educational community mandated school closures shifting instructional practices from a traditional face-to-face model into a remote instructional model (Bailey et al., 2021; Bawa, 2020; Domina et al., 2021; Onyema et al., 2020; Wyse et…

The problem is that Connecticut school principals face time allocation challenges impacting their ability to ensure student growth in reading and mathematics. With the knowledge of which actions have the greatest impact on student growth, principals can make strategic use of time to increase student achievement. The gap in the literature is that…

This quantitative, causal-comparative research study investigated whether school configuration has an impact on the reading performance of sixth-grade students by comparing the End-of-Grade (EOG) reading assessment Grade Level Proficiency (GLP) scores of sixth-grade students in K-8 configured schools to sixth-grade students enrolled in 6-8 grade…

It is now well established that the COVID-19 pandemic had a devastating and unequal impact on student achievement. Test score declines were disproportionately large for historically marginalized students, exacerbating preexisting achievement gaps and threatening educational and economic inequality. In this paper, we use longitudinal student-level…

Background or Context: Dual language education aims to foster the development of bilingualism, biliteracy, sociocultural competence, and academic skills in all school subjects. Early correlational research suggests that participation in dual language education is associated with higher achievement. Recent studies leveraged more comprehensive sets…

This study examined the impact of knowledge-building curricula on raising reading achievement for students from high-poverty backgrounds. The overall purpose of the study was to contribute to our understanding of curricula that may be effective in closing achievement gaps for students from lower socioeconomic backgrounds compared to…

In this brief we examine how variability in students' math and reading test scores changed across the pandemic, including whether increased dispersion was concentrated at one part of the test score distribution. Using reading and math assessment data from a sample of 8 million students in grades 3-8 in 24,000 public schools who took MAP Growth…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

Background: After elementary school, students in Germany are separated into different school tracks (i.e., school types) with the aim of creating homogeneous student groups in secondary school. Consequently, the development of students' reading achievement diverges across school types. Findings on this achievement gap have been criticized as…

Using a dataset that includes over 17 million students from across all 50 states, we estimate the causal impact of making structural transitions into middle school (in grades 4, 5, 6, or 7) on student math and reading achievement trajectories. This dataset provides an ideal opportunity to engage in the valuable scientific practice of conducting…

Introduction: Increasing evidence has shown that student mobility is negatively correlated with individual students' and schools' academic performance (Hanushek, Kain, & Rivkin, 2004; Lara, Mizala, & Repetto, 2011; Sun & Pan, 2014). However, the negative impact may be due to the switching behavior or it could be only a side effect of…

This report focuses on the COVID-19 pandemic in the Kalamazoo Public Schools District in Kalamazoo, Michigan, which closed its doors to students from mid-March 2020 to June 2021. During this time, instruction transitioned from face-to-face to virtual, with students having three options for virtual instruction. In addition to individual KPS student…

We study the distributional effects of remote learning using a novel approach that combines preference data from a conjoint survey experiment with administrative records of student outcomes. The experimentally derived preference data allow us to account for selection into remote learning while also studying selection patterns and treatment effect…

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage…

The present study investigates the effects of participation in academic extracurricular activities on student achievement in mathematics and reading in the course of secondary schooling. We use 2 samples of nonmandatory all-day schools that are part of the National Educational Panel Study (NEPS): N = 1,131 fifth graders at 43 schools were followed…
