We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

Closing the achievement gap has been a continuous topic of conversation in the United States for decades. School leaders have explored many ways to address the academic achievement of their marginalized student population. One approach has been the implementation of culturally relevant pedagogy and curriculum. By implementing a curriculum in which…

Public school board members are charged with the responsibility and accountability to provide governance-level advocacy for equity and excellence in public education. This qualitative study examined the perceptions of school board members in three K--8 school districts in the midwestern part of the United States regarding the 50+ year Race-Based…

Data reporting in the Australian education system produces deficit-based comparisons of academic achievement between Indigenous and non-Indigenous students. Since 2009, data from the National Assessment Program -- Literacy and Numeracy (NAPLAN) have been used by the Australian government to allow it to report on 'Closing the Gap' policy. These…

This study focused on a problem of practice at Mystic River School (MRS), a kindergarten through eighth grade school in an urban district in New England. Schoolwide diagnostic data showed a significant gap between multilingual learners (MLs) and their native English speaking peers in literacy. An analysis of this data, interviews with staff and…

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…

Australian children from regional, rural and remote (RRR) areas exhibit lower educational outcomes than their peers in metropolitan areas. The mechanisms driving the comparatively poorer educational outcomes of children in RRR areas, however, are not well understood. This paper proposes and tests two sets of factors that may be responsible for…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

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…
