Best High Schools in Zip Code 45833

ZIP code 45833 in Delphos, Ohio is home to exactly one high school: Jefferson High School, a public campus serving grades 6 through 12 with roughly 265 students in the Delphos City district. Because it is the district's only secondary campus, the district's numbers are essentially the school's own numbers rather than a separate comparison point. It is a small, rural school where a majority of students — 59.25% — qualify for free or reduced-price lunch, and the student-teacher ratio is a relatively modest 14.3. With all seven grades in one building, each individual grade level holds only about 35 to 45 students, so a single class can swing a subject's results considerably.

Academically, the school still beats the Ohio average in four of six tested subjects. American History is its strongest result at 88.2, about 15 points above the state, while Biology (81.6) and English II (75.0) both improved over the prior year and sit well above state averages. American Government scored 78.3, though that was an 11.7-point drop. Math is now the clear weak spot: Algebra I came in at 59.5 and Geometry at 41.5, the only two subjects below the state average. Geometry is the striking story — it fell from 76.3 to 41.5 in one year, turning from the school's best subject into its worst.

The broader trend is a steady slide in statewide standing: Jefferson ranked in the 87th percentile in 2023–24, the 81st in 2024–25, and the 61st in 2025–26, with its star rating slipping from 4 to 3. Chronic absenteeism is another concern at 25.7% — about one in four students missing 10% or more of school days — well above the district's 16.5% and the only measure where the school trails its own district. The graduation rate is 91.5%. Parents should weigh the three-year ranking trend more heavily than any single subject's one-year swing, since small cohorts make year-to-year changes volatile.
