This brief is a continuation of NWEA's research series examining the impact of the COVID-19 pandemic on student achievement and progress toward academic recovery. Initiated in the early phase of the pandemic, this series has leveraged NWEA's large national sample of longitudinal MAP® Growth™ data to track student performance and compare it to…

The purpose of this technical appendix is to share detailed results and to more fully describe the sample and methods used in the research included in the brief, "Recovery Still Elusive: 2023-24 Student Achievement Highlights Persistent Achievement Gaps and a Long Road Ahead." The authors investigated three main research questions in…

The extent to which reading achievement is causally impacted by eligibility for special education services due to a learning disability (LD) or speech or language impairment (SLI) is currently unclear. In this registered report, we analyzed U.S. national data from the Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 (ECLS-K:…

In 2014, the municipal water source in Flint, Michigan was switched, causing lead from aging pipes to leach into the city's drinking water. While lead exposure in Flint children increased modestly on average, some children were exposed to high lead levels. Surveys of Flint residents show the water crisis was also associated with increased levels…

This report outlines the results of the 2021 Progress in International Reading Literacy Study (PIRLS) in England. PIRLS is an international comparative study directed by the International Association for the Evaluation of Educational Achievement. The aim of PIRLS is to assess and compare the reading performance of pupils in their fourth year of…

The Study of Social and Emotional Skills (SSES) is an international effort led by the Organization for Economic Co-operation and Development (OECD) with Houston Independent School District (HISD) serving as the only U.S. site. Over 3,000 15-year-old students from 45 HISD campuses participated in SSES in the fall of 2019. Social and emotional (SE)…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

"Learning A-Z" contracted with Empirical Education to study the effectiveness of "Raz-Plus" in Milwaukee Public Schools during the 2016-17 school year. "Raz-Plus" is a literacy program that includes leveled books, skills practice, and digital activities and assessments. This study focused on 3rd, 4th, and 5th grade…

We identify externalities in human capital production function arising from sibling spillovers. Using regression discontinuity design generated by school-entry cutoffs and school records from one district in Florida, we find positive spillover effects from an older to a younger child in less affluent families and negative spillover effects from a…

Although there is evidence to suggest that parent involvement (PI) in children's education positively impacts their academic success, the mechanisms of this effect are less well studied. One potential mechanism is a set of student-level motivational and behavioral factors labeled approaches to learning (ATL). The purpose of the current study was…

Rising inequality in the United States has raised concerns about potentially widening gaps in educational achievement by socio-economic status (SES). Using assessments from LTT-NAEP [Long-Term Trend assessment administered by the National Assessment of Educational Progress], Main-NAEP, TIMSS [Trends in International Mathematics and Science Study],…

The purpose of this study was to investigate whether or not a child's chronological age at the onset of kindergarten influences foundational literacy skills and if there is an impact on long-term reading achievement. Research indicates that there are several factors that influence school readiness and the foundational literacy skills that must be…

In 2016, we recorded the highest levels of reading enjoyment to date, with nearly 6 in 10 saying that they enjoy reading either very much or quite a lot. Read more about children's and young people's reading enjoyment, based on our seventh annual literacy survey which we conducted in November/December 2016. 42,406 children and young people aged…

Students' early problem behaviors in school can be disruptive and even hinder their learning and long-term success. To prevent and address these problem behaviors, schools across the country report adopting Multi-Tiered Systems of Support for Behavior (MTSS-B). The MTSS-B approach seeks to change the school learning environment by consistently…

We apply "value-added" models to estimate the effects of teachers on an outcome they cannot plausibly affect: student height. When fitting the relatively simple models that are widely used in educational practice to New York City data, we find the standard deviation of teacher effects on height is nearly as large as that for math and…
