Sofia Postell 2025¶

Sofia Postell, Megan Kuhfeld, Susan Kowalski, Jazmin Isaacs. (2025). Hot test days, lower math scores: How heat affects student achievement. NWEA research brief. https://www.nwea.org/research/publication/hot-test-days-lower-math-scores-how-heat-affects-student-achievement/

q2 · i? · associational · r?

Observational analysis of roughly three million MAP Growth test events linked to daily temperature data across six states. The brief states students in high-poverty schools face "the greatest impact". No subgroup effect size is printed in the available text.

"the analysis finds that higher temperatures most strongly affect math scores, with students in high-poverty schools facing the greatest impact."

Related Claims¶

• The heat-achievement analysis links daily temperature data to MAP Growth scores for grades 3–8 in six states — related
• Heat effects on student performance may be more extreme for students in high-poverty schools where cooling conditions may be less reliable — possibly the same claim (merge candidate)
• Environmental temperatures on test days are associated with student math and reading performance, per the report this appendix documents — a broader claim this one bears on
• Higher temperatures most strongly affect math scores on test days — related
• As of 2020 about half of U.S. schools required HVAC upgrades, and many now face heat-related closures or shortened days — related
