Research brief
Boys regain the advantage in middle school STEM skills: Post-COVID trends in gender achievement gaps
May 2025
Description
Building on NWEA’s previous research series examining the impacts of COVID-19 related disruptions to learning, this study investigates how boys’ and girls’ achievement levels in STEM skills were affected. It starts by analyzing five years of data from three national assessments – TIMMS, NAEP, and NWEA’s MAP Growth – to estimate trends in gender gaps in 8th grade throughout the pandemic. The study then examines a sample of MAP Growth data from two million students to determine whether gender gaps widened among low- and high-achieving students. Finally, it explores whether enrollment in 8th grade Algebra varied by gender during and after the pandemic.

Should kindergartners be redshirted? Costs likely outweigh academic benefits
This research brief examines the data on holding back five-year-olds from starting kindergarten – a practice known as redshirting. Using national data from over three million kindergartners from NWEA’s MAP Growth K-2 assessment, this study explores redshirting trends between fall 2017 and 2025. It also follows a kindergarten cohort (2021-22) through the third grade, examining whether there were academic advantages for redshirted students.
