Related Claims¶

• Heat effects on student performance may be more extreme for students in high-poverty schools where cooling conditions may be less reliable — a narrower finding that bears on this claim
• Higher temperatures most strongly affect math scores on test days — a narrower finding that bears on this claim
• Students in high-poverty schools face the greatest impact from hot test days — a narrower finding that bears on this claim
• The heat-achievement analysis links daily temperature data to MAP Growth scores for grades 3–8 in six states — related
