We examined how children (N = 448) with separate or co-occurring developmental language disorder (DLD) and dyslexia performed on school-based measures of academic functioning between second and fourth grades. Children were recruited from 1 school district in the U.S. state of South Carolina via classroom screenings and met common research criteria…

This report is a continuation of work that examined the progress being made by districts to close the achievement gap in Kentucky (Butler and Poquette, 2019) and aims to further investigate the context in which districts are closing the achievement gap. Districts' achievement gap issues vary significantly: the size of districts' achievement gaps…

We use data from oral reading fluency (ORF) assessments to examine COVID-19's effects on children's ORF in over 100 U.S. school districts. Students' development of ORF largely stopped in spring 2020 following the onset of the COVID-19 pandemic. In fall 2020, students' gains in reading were stronger and similar to prepandemic rates. However, fall…

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…

Although research related to the Science of Reading has documented the positive effects of explicit, systematic reading instruction for all students, students from historically marginalized groups often experience differential opportunities to learn and are likely to perform lower than their peers on large scale measures of reading achievement.…

The purpose of this study is to investigate the progress being made to close the current achievement gap in Kentucky. Guiding the study is the following research question: Which districts are closing racial and socioeconomic achievement gaps at rates that exceed expectations? The authors assess districts' progress in closing racial and…

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 brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

Education has faced unprecedented disruption during the COVID-19 pandemic; evidence about the subsequent effect on children is of crucial importance. We use data from an oral reading fluency (ORF) assessment--a rapid assessment taking only a few minutes that measures a fundamental reading skill--to examine COVID's effects on children's reading…

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…

An achievement gap is defined as a significant difference in academic performance between two groups. Massachusetts Comprehensive Assessment System (MCAS) data indicate that, in Crestland Public School District (pseudonym), there is a clear achievement gap in mathematics between students with disabilities and those without disabilities,…

This study found that as early as the beginning of kindergarten and before any formal schooling began for most students, the achievement gap already existed. It was mostly related to students' poverty, ELL status, and SWD status, as well as to schools' having larger proportions of economically disadvantaged students. Students from poor families…

Using testing data from 2.1 million students in 10,000 schools in 49 states (plus D.C.), we investigate the role of remote and hybrid instruction in widening gaps in achievement by race and school poverty. We find that remote instruction was a primary driver of widening achievement gaps. Math gaps did not widen in areas that remained in-person…

This report features components of Arizona's plan under the Every Student Succeeds Act that impact the 85,000 English learners in the state regarding testing, accountability, and stakeholder engagement. Advocates can use this information to engage administrators and policymakers around improving outcomes for English learners and ensuring they…
