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 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…

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…

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…

This brief provides a policy perspective into the recent NWEA research on how COVID-19 has affected student learning. It builds on previous research showing achievement levels stalling over the 2022-23 school year from the previous year. This analysis on student learning from grades 3-8 shows that academic recovery has stalled for older learners…

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, "Progress toward Pandemic Recovery: Continued Signs of Rebounding Achievement at the Start of the 2022-23 School Year" (ED627355). The two main research questions…

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…

In our report, "Learning during COVID-19: Initial findings on students' reading and math achievement and growth," we examine how school shutdowns impacted student achievement at the start of the 2020-21 school year. Using data from schools all over the country, we've built these visualizations to explore three key questions: (1) How have…

Metadata that are often captured and discarded when students take achievement tests on a computer can transform processes for identifying, monitoring, and supporting students who might benefit from social-emotional learning (SEL) interventions. This submission presents a metric called response-time effort (RTE) that relies on such metadata. The…

This simulation study examines the measurement precision, item exposure rates, and the depth of the MAP® Growth™ item pools under various grade-level restrictions. Unlike most summative assessments, MAP Growth allows examinees to see items from any grade level, regardless of the examinee's actual grade level. It does not limit the test to items…

This report examines the academic impact of the COVID-19 pandemic on Black, Indigenous, and people of color (BIPOC) students, with the goal of documenting achievement trends to provide leaders and policymakers with evidence to guide action to address educational inequities for BIPOC students. Using math and reading test data from 2.1 million BIPOC…
