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…

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 aimed to describe 1-year changes in students' vocabulary in written narratives. Secondary aims included examination of accuracy and the relationship between lexical diversity and achievement. Participants included 749 students in first through eighth grades. Within-subjects 1-year change in diversity, productivity, and accuracy was…

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…

Preschool programs provide opportunities to improve early childhood educational outcomes as well as long-term outcomes, such as improved educational attainment, improved socioeconomic status, and improved health in adulthood. However, recent studies of long-term impacts have shown equivocal results, with some educational gains occurring…

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…

Extensive literature highlights positive outcomes experienced by students whose parents and teachers have strong relationships, but less is known about the factors that influence parent-teacher relationship strength. Using data from "The Impact of Grade Retention: A Developmental Approach," we identify parent-level predictors of the…

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…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

This research brief examines the continuing impact of the COVID-19 pandemic on student achievement and progress toward academic recovery. Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also tracked the gap in…

This is the technical index for the research brief "Education's Long COVID: 2022-23 Achievement Data Reveal Stalled Progress toward Pandemic Recovery." Using data from 6.7 million U.S. public school students currently in grades 3-8, the study examined academic gains in the 2022-23 school year relative to pre-pandemic years. It also…
