Data Sources & Methodology
Every figure on 901 Education carries a source citation and a data vintage. This page shows the live status of each dataset the dashboard publishes, and the standards we hold ourselves to.
Data integrity standards
- — Never display a metric without a source citation and data vintage.
- — Distinguish what the data shows from what we claim it means; interpretation is labeled.
- — When TDOE suppresses data (n<10, or proficiency <1% / >99%), we show the suppression — we never interpolate or estimate.
- — Trend over snapshot: single-year education data is almost always misleading.
- — COVID-disrupted years (2019-20, 2020-21) are flagged as anomalous.
- — Denominators are stated: graduation = 4-year cohort; chronic absenteeism = % of enrolled students missing 10%+ of days.
- — Annual fact-check pass before each data update goes live.
Primary public sources

All data is publicly released by government agencies at the aggregate level — no student-level records are collected or published. Corrections: open an issue on the project repository and it will be reviewed before the next data pass.
