- 2How it was computedvalue = published 4-year cohort graduation rate (district file, indexed by cohort entry year; state file, indexed by report year)
- Read the district's graduation CSV (all cohorts, 4/5/6-year rates, by subgroup) and store by cohort year.
- The state's Future Ready file also carries a 4-year rate for every school including charters; it is stored under the same key but indexed by report year.
Note: stored percentiles are computed by a batch script after loads; a difference from the live reconstruction means a newer load changed the comparison set and the batch has not been re-run.

- 7Assumptions & caveatsAssumptions and caveats
- The two publishers' rows never collide on (school, year, subgroup) because they use different year conventions; readers must check which convention a given year follows.
- Two year conventions coexist under one key — a known v1 wart flagged for normalization.
