School choice is spreading across the U.S. at the same time that scores on the National Assessment of Education Progress (NAEP) are stagnant. We examine the association between education freedom and 8th grade student NAEP score levels and gains in states in 2019. We construct the 2019 Education Freedom Index as a composite measure of the…

Prior research has found that financial investments in North Carolina's early childhood education programs--Smart Start and NC Pre-K--generated positive effects on student achievement in reading and mathematics through eighth grade (Bai et al., 2020). The current study examined if these effects were moderated by two dimensions of educational…

The 2007 Public Education Reform Amendment Act led to 39 percent of the principals in District of Columbia Public Schools (DCPS) being dismissed before the start of the 2008-09 school year, and additional principal exits over the next few years. We measure the impact of replacing these principals on schoolwide student achievement by measuring the…

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…

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 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…

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…

The disruptions to schooling created by the COVID-19 pandemic prompted nationwide concern about negative impacts on academic proficiency, particularly for vulnerable student populations. Pennsylvania's 2021 statewide assessments offered the first opportunity since the pandemic began to assess how students across the Commonwealth were faring,…

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…

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, "Learning during COVID-19: An Update on Student Achievement and Growth at the Start of the 2021-22 School Year." The goal of this brief is to summarize student achievement…

This brief is a continuation of NWEA's ongoing research agenda focused on understanding how the COVID-19 pandemic has affected student reading and math outcomes. This report builds on previous findings to examine students' academic progress at the start of the third school year impacted by the pandemic. The goal of this brief is to summarize…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that measures trends in mathematics and science achievement at the 4th and 8th grades every 4 years. TIMSS is designed to align broadly with mathematics and science curricula in the participating education systems and, therefore, to reflect…

We use a quadratic equation to estimate trends in cohort performances in the charter and district sectors on the National Assessment of Educational Progress in 4th and 8th grade between 2005 and 2017. Data consist of over four million test observations of nationally representative samples of students on seven separate math and reading tests. We…
