How we compare income gaps
“Typical” means the median gap across 66 schools for reading and 66 for math. The comparison uses 2026 California 7–12 schools with at least 20 tested students in each income group and a reported low-income student population. Each school counts once. Its gap is non-low-income proficiency minus low-income proficiency, including negative gaps. California state test data
