Summary:
Three schools serve students from prekindergarten through grade 12 in zip code 61360: Seneca Grade School North Campus (PK–4), Seneca Elementary School South Campus (grades 5–8), and Seneca High School (grades 9–12). The clearest broad strength is at the two lower-grade campuses: in 2025–2026, both were above the state in all-grades English and math, with their average math result 19 percentage points above the state.
North Campus led the lower-grade schools in all-grades math at 64%, compared with 54% at South Campus and 40% statewide; North also narrowly led in English, 68% to 67%. South had standout results in eighth-grade English (82%, 19 points above the state) and sixth-grade English (77%, 19 points above), but seventh-grade English was 50%, 8 points below the state. At Seneca High, grade 11 ACT English (60%) and science (54%) exceeded state results by 10 and 6 points, while math (30%) was 10 points below.
Results changed in different ways across schools and subjects. From 2024–2025 to 2025–2026, North and South each improved in all-grades math, and their average advantage over the state grew by 5 points; their average English advantage narrowed by 2 points. Seneca High’s ACT results also rose—by 6 points in English, 9 in math, and 11 in science—but math remained below the state. SchoolDigger’s latest rankings placed South at the 77th percentile, North at the 76th, and Seneca High at the 65th. For 2024–2025, student-teacher ratios were 10.4 at South, 9.3 at North, and 9.9 at the high school; all reported free/reduced lunch eligible figures for that year, ranging from 32% at the high school to 37% at South, as context rather than an explanation of results.
