Summary:
Horizon Science Academy-Dayton is a single-school elementary district in Dayton, Ohio (4751 Sue Ann Blvd), serving grades K–5 with 182 students, so it is a small, self-contained campus rather than a network of neighborhood schools. With roughly 30 students per grade, one child is worth about 3 percentage points in any grade-level result, which means year-to-year swings should be read with caution.
The school's results are weakest in third grade, the entry point for state reading and math testing. Third grade math was 22% proficient in 2025-26 and 27.5% in 2024-25, against state rates of about 62% both years — the largest gap in the file and the most stable weak spot. Fifth grade is the school's strongest area: fifth grade English language arts hit 60% proficient in 2024-25 and 54.5% in 2025-26, the only results above 50% and the closest the school came to the state (about 16 points back). Fourth grade math reached 65% in 2024-25, within about 4 points of the state, but fell to 34.3% in 2025-26. Overall, the school averaged 32.5% proficiency in 2025-26 versus a state average of about 63.8%, and it trails the state in all seven tested grade-and-subject areas. Reading (37.5%) outperforms math (29.4%).
For parents, two things stand out. First, every tested area declined between 2024-25 and 2025-26 — an average drop of roughly 13 points — and the school's ranking slipped from the 28th percentile to the 12th, below where it stood two years earlier. Second, chronic absenteeism reached 41.3% in 2025-26, meaning about two in five students missed enough school to be flagged; that is the single largest figure in the file. On the positive side, the student-teacher ratio is a small 11.3. Note that free/reduced lunch data is not reported, and the spending figure ($8,883 per student) dates to 2018-19, so both are too limited or too old for judging current conditions.
