To describe the impact of the COVID-19 pandemic on students, researchers have translated test scores into months of learning to claim how many months/years students are behind in school. Despite its perceived accessibility, there are major downsides to this translation. To inform future uses by researchers and media, we discuss in this brief how to calculate this metric as well as its trade-offs.

This visualization was developed to provide state-level insights into how students performed on MAP Growth in the 2020–2021 school year. Assessments are one indicator, among many, of the student impact from COVID-19. Our goal with this tool is to create visible data that informs academic recovery efforts that will be necessary in the 2022 school year and beyond.

The purpose of this technical appendix is to share more detailed results and describe the sample and methods used in the research in Education’s long COVID: 2022-23 achievement data reveal stalled progress toward pandemic recovery report.

New research shows progress toward academic recovery stalled in 2022-23. This research brief covers data from 6.7 million US students examining academic gains relative to pre-pandemic years as well as tracking the gap in achievement between COVID year student groups compared to their pre-pandemic peers.

New research provides evidence that student reading and math achievement at the start of the 2022–23 school year is continuing to rebound from the impacts of the pandemic, though full recovery is likely still several years away.

The purpose of this technical appendix is to share more detailed results and describe the sample and methods used in the research in Progress towards pandemic recovery: Continued signs of rebounding achievement at the start of the 2022-23 school year.

New research provides additional evidence of the uneven impacts of the COVID-19 pandemic showing that students’ math and reading test scores are more variable in spring 2022 than before the pandemic in part because the divide between high and low achievers has widened.
