A New Work of Synthesis
Government agencies publish raw tables; School Decision combines those sources into reporting and analysis. Every school and district record in the research corpus integrates information from approximately a dozen distinct source datasets, cross-referenced against geographic, economic, and demographic baselines.
The transformation from input to output is non-trivial and represents the substantive analytical work of School Decision.
Source Material as Input
Raw inputs are sourced exclusively from authoritative federal and state datasets: the U.S. Department of Education's Common Core of Data, the Civil Rights Data Collection, the EDGE program's geocoded school-locator file, Small Area Income and Poverty Estimates, state-level assessment exports from individual state education agencies, and macroeconomic indicators from FRED and Zillow research.
These are public-domain records, but they exist in heterogeneous formats such as fixed-width files, pipe-delimited exports, state-specific encoding conventions, and inconsistent schema across federal and state boundaries. No source publishes them in a form usable by a parent making a school-selection decision. The work of making them usable is itself the value.
Cross-Source Synthesis
Our analytical layer integrates approximately twelve distinct source datasets per school and district record in the research corpus, resolving identifier conflicts across federal and state systems and building the cross-reference machinery (NCES-to-FIPS crosswalks, EDGE geocoded coordinates, charter-status resolution) that allows a single school's record to inhabit a unified analytical frame. This integration step is not present in any source dataset.
A report on a district in Guam, rural West Texas, or Brooklyn can synthesize academic performance against state and county baselines, demographic context drawn from federal civil rights data, housing market context from Zillow, and economic context from FRED. None of which the source agencies present together. The synthesis is original work.
Comparative Analysis
For each school and district record, we compute peer-comparison artifacts that situate the entity within county, metro, and state contexts. These comparisons — academic performance percentiles relative to similar districts, demographic composition relative to county baselines, and financial metrics relative to state norms — are analytical research artifacts produced by our pipeline against the unified corpus, not a public comparison product.
No source agency publishes these comparisons. They are derivative analytical works produced by School Decision and are protected as such.
Editorial Narrative Authorship
The most substantive layer of original work is editorial narrative: paragraph-form interpretation of how a school system is changing. These narratives are not summaries of source data. They are original editorial works that synthesize multiple data sources, apply consistent analytical framing across reporting and research, and surface what the evidence shows.
The narratives are produced through a proprietary three-stage research-and-writing pipeline:
Stage 1: Research
Independent contextual research is performed against open web sources for each locale and district, surfacing parent-relevant developments like recent policy changes, capital investments, demographic shifts, and district initiatives that contextualize the analytical data. These context briefs are themselves original derivative works, drawn from media coverage and authoritative reporting, synthesized into a structured format suitable for downstream analysis.
Stage 2: Comparative Analytics
Deterministic peer-comparison artifacts are generated from the unified corpus, situating each entity within geographic and demographic peer cohorts.
Stage 3: Editorial Synthesis
A constrained editorial writing step assembles the contextual research, comparative analytics, school-level facts, and district programs into a parent-actionable narrative. The narrative follows School Decision's editorial standard: factually grounded, action-oriented, free of decontextualized rankings, and respectful of the limitations of the underlying data. Narratives explicitly omit specific figures that would reduce the editorial work to a recitation of source-data tables; the prose conveys interpretation, not transcription.
Editorial Standard
School Decision applies a consistent editorial standard across reporting and research that no source agency applies to its own data. We do not publish proprietary ratings. We do not aggregate test scores into single-number quality scores. We do not present federal civil rights data in ways that would invite reductive judgments about schools.
We surface inactive or alternative-program facilities with appropriate context rather than burying them. We attribute every factual claim to its source. This editorial frame is School Decision's editorial standard and is consistent across reporting and research.
Data Quality and Integrity
Our pipeline implements production-grade quality controls that source agencies do not apply to their published data. Every record carries immutable lineage to its originating source, version, and retrieval date. Every artifact is content-addressed with SHA-256 verification. Every state's coverage is validated against expected entity counts before deployment.
State-specific structural quirks such as Texas's Education Service Centers, New York's BOCES, and California's County Offices of Education are systematically identified and excluded from consumer-facing surfaces through a shared analytical filter rather than handled case-by-case. The corpus represents not just the integration of source data, but the application of consistent quality standards across heterogeneous federal and state sources.
What the published record covers
School Decision maintains national school and district datasets and publishes original reports in selected metros. Editorial narratives cover selected states and places. We do not claim a worldwide school census or complete original treatment of every school.
The method page explains how evidence becomes published interpretation. It is not a marketing account of the engineering pipeline.
Republication Policy
Source data is republished in its original form with attribution. Synthesized comparisons, analytical derivations, and editorial narratives are original works owned by School Decision and are not licensed for redistribution.
Researchers interested in source data should consult the originating agencies. Researchers interested in our analytical or editorial work should contact School Decision directly.
