   How it was computedvalue = published 5-year cohort graduation rate, by cohort entry year

   1. Read the district's graduation CSV and store the 5-year rate by cohort 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.

   To confirm you have the same file: download it from the URL above, then run shasum -a 256 <downloaded file> Copy command — 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.
