Public data
Data Sources
Assessment Data
Achievement rankings use Arizona Department of Education school-level assessment workbooks for fiscal years 2023, 2024, and 2025. The current methodology uses verified Grade 11 proficiency-band rows for ACT English Language Arts, ACT Mathematics, and AzSCI Science.
School Context Data
School identity, address, grade span, enrollment, race/ethnicity membership, virtual-status classification, locale, county, latitude, and longitude come from NCES Common Core of Data and NCES EDGE public school geocode files. Demographic percentages are suppressed when total enrollment is below 11.
Known Gaps
Economic-disadvantage context is intentionally left unavailable until a sufficiently complete Arizona source is verified. Some ADE school IDs are not yet matched to NCES; those unmatched IDs are tracked in the generated data artifact and raw data ledger.
