Summary:
Zip code 61548 has four schools—two elementary schools, one middle school and one high school—with reported assessment results spanning grades 3–11. The elementary and middle schools’ scores are above the state in every reported grade-level comparison, and Metamora High School is also above the state in grade-11 ACT proficiency: 63% in ELA, 60% in math and 60% in science, compared with state results of 50%, 40% and 48%. The most important finding is that strong state comparisons coexist with sizable differences among local schools and grades.
Germantown Hills Middle School stands out in grades 5–8 ELA, leading its same-grade comparisons in all four grades; in grade 8, it scored 94%, versus 67% at Metamora Grade School, a 27-point gap. The grade-8 math gap is even wider: 86% at Germantown Hills Middle versus 44% at Metamora Grade, a 42-point difference. But the lead changes by grade and subject: Germantown Hills Elementary School leads grade 3 ELA and math, while Metamora Grade leads grade 4 math by 3 points and grade 5 science by 2 points. Germantown Hills Middle leads grade 8 science by 16 points.
Recent changes are mixed rather than uniformly upward: across the three IAR schools, the all-grades ELA average rose 2 points from 2024–25 to 2025–26, while math was essentially unchanged; the state improved in both subjects, slightly narrowing the local average advantage. High-school trends also differ by subject: Metamora High’s grade-11 ACT ELA fell 5 points, math rose 1 and science fell 2. SchoolDigger rankings moved from the 76th to the 84th percentile for Metamora Grade, while Germantown Hills Elementary shifted from the 93rd to the 91st and Germantown Hills Middle from the 97th to the 96th. Reported free/reduced lunch eligible shares in 2024–25 ranged from 17% to 22%; student-teacher ratios ranged from 13.8 to 15.4, offering context but not a simple explanation for score differences. Because schools cover different grade spans, same-grade comparisons are more useful than all-grades averages.
