SchoolMap aggregates publicly available federal and state education data. All datasets are updated annually.
The CCD is the U.S. Department of Education's primary database on public elementary and secondary education. It provides directory information for every public school and local education agency (LEA) in the country — including name, address, phone, grade span, type, and operational status.
Student enrollment counts broken down by grade, race/ethnicity, and sex. Used for total student counts, gender ratios, and racial/ethnic demographic breakdowns shown on each school and district page.
Students eligible for free or reduced-price lunch under the National School Lunch Program. Used as a proxy for the share of low-income students in a school or district.
Full-time-equivalent (FTE) teacher counts per school, used to compute the student-to-teacher ratio.
Smarter Balanced Assessment Consortium scores for California public schools and districts — Math and ELA (English Language Arts) proficiency rates for all tested students. Used to compute SchoolMap's 0–10 performance ratings. Only entities with ≥ 100 tested students are scored.
Latitude and longitude coordinates for public schools, used to place school pins on the map.
School district boundary polygons from the U.S. Census Bureau, used to draw district shapes on the map.
Data currently reflects the 2024–2025 school year for directory and enrollment data, and the most recent available year for SBAC assessment scores.
