“2025 admissions” means students who sat the SHSAT as eighth graders in the 2024-25 school year and received offers for fall 2025, as in the DOE’s admissions outcomes report. “8th graders” counts the school’s eighth graders who applied to high school; “took the test” divides testers by that count when both are published. The district row adds the published counts of its schools, so its offers are a floor; the city row is the DOE’s own total. “Not listed” means the school is absent from that year’s file.
