Summary:
Horizon Science Academy Dayton High School is the only school in this data set and operates as its own district, so there are no other schools in the area to compare against — the only benchmarks available are the school's own results over time and Ohio statewide averages. It is classified as a high school but actually serves grades 6 through 12, with 300 students and a 12:1 student–teacher ratio in 2024-2025. Located at 250 Shoup Mill Rd in Dayton, it is the only place where 6th, 7th, and 8th grade students are visible in the data, since the area summary counts zero middle schools.
Academically, every one of the school's 12 current test measures sits below the state average, by an average of nearly 33 points. The composite school average was 25.5% proficient in 2025-2026 versus 58.4% statewide, up from 21.4% versus 58.2% the year before. The strongest results are 7th grade ELA at 50% and Geometry at 32.4%; the weakest are 8th grade Science at 12.2% against 61.2% statewide, English II at 18.4% versus 62.7%, and Algebra I at 18.9% versus 61.6%. Middle-grade math has not exceeded 20% proficiency in any grade in either year. The school ranks in the bottom decile of Ohio high schools — 10th percentile, 1 star — though its 2023-2024 result of 21st percentile remains its best position.
Two numbers stand out in opposite directions. The graduation rate is 93.1%, the strongest figure in the record, and it sits alongside very low end-of-course proficiency — a tension worth asking the school about directly. Meanwhile, chronic absenteeism is 67.8%, meaning roughly two of every three students missed at least 10% of the school year. Note that the free/reduced-lunch figure is not reported, and the only spending figure, $8,324 per student, dates to 2018-2019 and does not reflect current funding.
