To what extent has the COVID-19 pandemic affected student achievement and growth in reading and math, and which students have been most affected? Using data from 6 million students in grades 3-8 who took MAP Growth assessments in reading and math, this brief examines how gains across the pandemic (fall 2019 to fall 2021) and student achievement in fall 2021 compare to pre-pandemic trends. This research provides insight to leaders working to support recovery.

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. We investigated two research questions:

1. How does student achievement in fall 2021 compare to pre-pandemic levels (namely fall 2019)?
2. How did academic gains between fall 2019 and fall 2021 compare to normative growth expectations?

Using achievement data from fall and spring of grades K-8 for 840,000 students in 8,800 public schools, this study provides novel evidence on how achievement and growth differ between rural and nonrural schools. Rural students start kindergarten slightly ahead of nonrural students but fall behind by middle school. The divergence is driven by larger summer losses for rural students. In both rural and nonrural schools, Black–White achievement gaps widen during the school year.

How does schooling affect inequality in students’ academic skills? This study uses seasonal comparisons to examine the possibilities that schooling exacerbates, reduces, or reproduces overall skill inequality in math, reading, language use, and science with recent national data on US public school students spanning numerous grade levels from the NWEA MAP Growth assessment. Results suggest that schooling has a compensatory effect on inequality in reading, language, and science skills but not math skills. Theoretical implications of findings are discussed.

Black and poor students are suspended from U.S. schools at higher rates than White and nonpoor students. While the existence of these disparities has been clear, the causes have not. By comparing the punishments given to Black and White (or poor and nonpoor) students who fight one another, the study addresses a challenge that has kept prior studies from identifying discrimination in student discipline. It finds that Black and poor students are punished more harshly than the students with whom they fight.

The MAP Reading Fluency theory of action shows the hypothesized mechanisms of change and intermediate goals leading to the overarching goal of helping all students read fluently with comprehension.

To what extent did COVID-19 disruptions affect student achievement in 2020-2021, and which students have been most affected? New NWEA research aims to provide insight to inform leaders working to support recovery: using data from 5.5 million students in grades 3-8 who took MAP Growth assessments in reading and math, this brief examines how gains across the 2020-21 school year and student achievement in spring 2021 compare to pre-pandemic trends.
