How we compare income gaps
“Typical” means the median gap across 301 schools for reading and 302 for math. The comparison uses 2026 California 7–8 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
