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…

The purpose of this study was to analyze the impact of the reading program, System 44, on students with learning disabilities in grades six and seven at a small rural middle school. The middle school implemented the reading program during the 2018-2019 school year to assist students reading below grade level to "catch up" or close the…

This "ex post facto," causal-comparative quantitative study assessed the math and English language arts (ELA) 7th to 8th-grade academic growth among Black students enrolled in Philadelphia's black-operated public charter schools, non-black operated charter schools, and traditional public schools while controlling for 6th-grade exam…

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…

Background/Context: Increasing evidence suggests a connection between racial differences in rates of exclusionary discipline (suspensions/expulsions) and academic achievement by (Losen & Martinez, 2020; Reardon et al., 2018). Black students receive out-of-school suspensions and expulsions at disproportionately higher rates, which is associated…

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…

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…

Improving youth science comprehension is critical to youth development, yet this intended outcome is often overlooked in terms of how Extension programs are delivered. The purpose of the study reported in this article was to determine through the assessment of potential student growth whether applying features of a youth science comprehension…

This longitudinal study examined the outcomes of Project Excite on reducing minority students' achievement gaps in STEM over 14 years. Project Excite was designed to provide intensive supplemental enrichment and accelerated programming for high-potential, underrepresented minority students from third through eighth grades to better prepare them…

Using four-wave longitudinal reading and mathematics data (4th to 7th grades) from a large urban school district, growth curve modeling was used as a tool for examining three research questions: Are achievement gaps closing in reading and mathematics? What are the associations between prior-achievement and growth across the reading and mathematics…

The study examined differences in reading achievement and mastery skill development among Grade-6 students with different language background profiles, using cognitive diagnosis modeling applied to large-scale provincial reading test performance data. Our analyses revealed that students residing in various home language environments show different…

Extending the school day through programs that will supplement core courses, such as offering intensive, after-school tutoring or small-group study sessions in reading and mathematics, is one method districts use to boost school performance and narrow educational achievement gaps between students of different racial and economic backgrounds (Redd…
