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.
