    How it was computedvalue = published 4-year cohort graduation rate (district file, indexed by cohort entry year; state file, indexed by report year)
    1. Read the district's graduation CSV (all cohorts, 4/5/6-year rates, by subgroup) and store by cohort year.
    2. 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.

    Citywide percentile, reconstructed right now

    Among 25 default-included schools with a value for this metric, year, and subgroup, this school has a higher value than 13. Midrank rule: (13 + 0/2) / (25 − 1) = 0.542.Stored: 0.542. ✓ matches

    How percentiles are computed · How peer groups are chosen

    Peer percentile, reconstructed right now

    Peer group: up to 40 of the demographically nearest schools among High / catchment / district schools; 8 of 20 peers have a value this year. This school is above 7 of them. Midrank: (7 + 0/2) / (9 − 1) = 0.875; stored 0.875. ✓ matches

    The peers and their values (8)

    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.

    To confirm you have the same file: download it from the URL above, then run shasum -a 256 <downloaded file> — the output should equal the hash above. If the publisher has since replaced the file, the hashes will differ, which is itself useful to know.

    Assumptions & 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.

    Algorithms involved: Citywide and peer-group percentiles, Peer groups: 40 nearest neighbors on demographics
