Public school data, translated for comparison.
School Atlas is a national normalization layer for public K–12 accountability data.
State education systems publish school performance information using different methodologies, definitions, and reporting structures. School Atlas translates those public data sources into a consistent framework for cross-state comparison.
School Atlas does not generate measurements. It standardizes publicly reported state education data into a common structure for researchers, analysts, and policymakers.
Each school receives a normalized School Atlas Score (0–100) derived from publicly reported state accountability metrics.
Metrics vary by school level and state availability, and may include reading proficiency, math proficiency, graduation rate, chronic absenteeism, college readiness, student-teacher ratio, and academic growth.
Scores are calculated using a versioned, auditable policy framework. School Atlas scores are not rankings, ratings, or judgments of school quality. They are standardized representations of publicly available data.
Because states publish different levels of information, School Atlas displays a data completeness tier for every school. This tier reflects data availability only, not school performance.
Currently includes Oregon, Arizona, and California for the 2025 academic year. Washington is in progress. Additional states are added as normalization pipelines are completed and validated.
School Atlas uses publicly available data from state education agency accountability systems, the NCES Common Core of Data, and NCES attendance zone boundary datasets.
Data reflects the most recently available academic year published by each state.
