Summary
Jefferson Middle School in Delphos, OH, is a grades 5–8 school in the Delphos City district serving 248 students in a small northwest Ohio community. In 2025–2026, it ranked 377th of 1,046 Ohio middle schools (64th percentile, 3 stars), while the district ranked 227th of 773 (71st percentile, 4 stars), so the middle school is currently below its district’s overall standing.
Jefferson’s biggest academic strength is English language arts and science: in 2025–2026, proficiency was above the state in ELA and science at every tested grade, including 6th-grade ELA at 78.9 versus the state’s 56.0. Math is the clear weakness, especially in 5th grade (47.4 versus 59.1 statewide) and 8th grade (44.4 versus 52.0). Nearby schools such as Columbus Grove Middle School, Spencerville Middle School, Bath Middle School, Shawnee Middle School, Parkway Middle School, and Crestview Middle School posted 8th-grade math proficiency well above Jefferson’s, while Van Wert Middle School and Lima West Middle School were similar or lower. Algebra I proficiency fell from 100% in 2022–2023 and 2023–2024 to 70.6% in 2025–2026, still above the state’s 61.6% but behind nearby schools at or near 100%.
Jefferson has a high and rising economic disadvantage rate — 70.56% free/reduced lunch in 2024–2025 — yet its Low Socio-Economic Status subgroup ranked in the 81st percentile (4 stars), a genuine bright spot. Chronic absenteeism was 18.0% in 2025–2026, higher than Columbus Grove Middle School, Spencerville Middle School, Crestview Middle School, Parkway Middle School, Bath Middle School, and Shawnee Middle School. The school has declined from the 94th percentile in 2018–2019 and 93rd in 2020–2021 to 56th in 2024–2025, then rebounded to 64th in 2025–2026. Class size and per-student spending look similar to nearby districts, so the most promising improvement levers are math instruction in grades 5–8, Algebra I preparation, and reducing absenteeism while preserving strong literacy, science, and low-SES outcomes. It outperforms Lima North Middle School and Lima West Middle School and is roughly comparable to Elida Middle School, but trails the region’s strongest middle schools in math.
