Data limitations
- Graduation uses state cohort data. Coursework, offerings, and SAT/ACT counts use the latest available federal CRDC extracts, which can lag current graduation data.
- SAT/ACT data is count-only in this extract; without an enrollment denominator, we do not treat it as a participation rate.
- HS Decoded Rank is alpha-only: it summarizes how the school's grade 10/11 test scores compare to expectations from its demographic context, ranked against other HSs in the same metro / state / rural cohort. Graduation, AP, and SAT/ACT data above are descriptive context — they are not yet blended into the composite rank. The achievement-vs-decoded quadrant below plots context-adjusted ACHIEVEMENT (alpha) against raw achievement; it is NOT the growth-based composite shown for elementary and middle schools, because a single-tested-grade high school has no consecutive-grade cohort ladder from which to build a growth signal.

- Methodology published
This score uses state assessment data, NCES enrollment data, and Census ACS 5-year neighborhood data. The Decoded Rank adjusts for school context — student demographics, ELL/SPED service rates, and the socioeconomic profile of the surrounding tract — and shows how the school performs relative to expectation, not in absolute terms.
SchoolDecoder is one signal, not a verdict. Decoded Rank is a context-adjusted residual, not a causal claim about teaching quality. See full methodology →
