Highest four-year graduation rates
The share of a district's cohort graduating within four years, from NYSED's official release. Reported for 96 of New York's 724 districts — all of them on Long Island, which is the only region the state publishes district-level rates for. A high rate says students finished; it says nothing about what came after, or what it cost.
