How these rankings work

Rankings use the latest available California reading and math results. Schools are compared with other California schools serving similar grade levels. Medians describe the typical local result and are not districtwide averages. Virtual schools are excluded, and cities with fewer than three scored schools are omitted from the indexed location directory.
