It was a 4-star school from 2015–16 through 2020–21, with percentiles between 72 and 82, but has held 3-star status since 2021–22, with percentiles between 55 and 61 — though 2025–26 is a slight rebound from 55th percentile in 2024–25.
Among 10 nearby middle schools, St. Marys ranks 9th of 11, ahead of only Wapakoneta Junior High (59th percentile) and Lima West Middle School (8th percentile). It trails higher-performing neighbors such as St Henry Middle School (97th), Anna Middle School (91st), Coldwater Middle School (91st) and Celina Middle School (72nd). Math in grades 6 and 8 is a strength: 75.2% proficient in Math 6 (state 56.2%) and 69.2% in Math 8 (state 52.0%). Algebra I proficiency is 100%, though this likely reflects a small, selective group (district average 62.5%). Grade 7 math is the clearest weakness at 38.6%, 10 points below the state and the lowest among nearby schools except Lima West. Grade 7 ELA (59.3%) is also below state and below every nearby school except Lima West.
St. Marys serves a far more economically disadvantaged population than most neighbors: 99.33% of students qualified for free/reduced lunch in 2024–25, versus 40.17% at Shawnee, 49.43% at Celina and 47.07% at Wapakoneta Middle School. Despite this, the school exceeds state averages in Math 6, Math 8, ELA 6, ELA 8, Science 8 and Algebra I. Internally, results diverge sharply: gifted and talented students ranked 5th of 186 (97th percentile, 5 stars), while special education students ranked 425th of 579 (27th percentile, 1 star). Chronic absenteeism was 12.0% in 2025–26 — better than Lima West, Wapakoneta Junior and Shawnee, but higher than most nearby high performers. The student-teacher ratio improved to 16.3 in 2024–25, and per-student spending was $7,124 in 2018–19.
