Graduation is 100% in 2025–2026 and 2024–2025. Chronic absenteeism improved from 26.0% in 2021–2022 to 12.6% in 2025–2026, but it remains higher than the district’s 7.9% and much higher than top nearby schools such as Versailles High School (3.0%), Russia High School (3.4%), Marion Local High School (3.8%), and Fort Recovery High School (4.1%). The school has a 9.1 student-teacher ratio and $13,577 per-pupil spending in 2018–2019, the highest among nearby schools.
Academically, 2025–2026 End-of-Course results are mixed but mostly above state averages. Geometry is a standout at 75.0 versus Ohio’s 43.3; Government is 88.4 versus 71.6, American History 83.1 versus 73.2, English II 72.1 versus 62.7, and Algebra I 71.7 versus 61.6. Biology is the clear weakness at 63.5, below Ohio’s 67.0 and far behind nearby high performers like Fort Recovery High School (96.4), Marion Local High School (96.4), and Russia High School (94.4). The school’s state rank has softened over time, from the 89th–90th percentile in 2015–2016 through 2018–2019 to the 72nd percentile in 2025–2026.
Subgroup results show a stark split. Low-socioeconomic-status students rank 63 of 761 (92nd percentile, 5 stars), a standout strength, while special education students rank 474 of 575 (18th percentile, 1 star), a clear concern. Locally, Ansonia High School generally does better than Greenville Senior High School, Bradford High School, and Mississinawa Valley Junior/Senior High School, but trails nearby elite schools including Marion Local High School, Versailles High School, St Henry High School, Russia High School, and Fort Recovery High School. With only 217 students, each grade is roughly 50–55 students, so year-to-year scores can swing sharply: Biology went from 87.5% to 63.5%, and Geometry from 50.0% to 75.0%.
