How we compare income gaps
“Typical” means the median gap across 3 schools for reading and 3 for math. The comparison uses 2026 California 4–12 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
