The school’s strongest finding is that it outperformed the state in every reported subject, by 20 points in ELA, 13 in math, and 12 in science.
Mascoutah Middle School is both the highest- and lowest-scoring school in this ZIP-code list because it is the only one, so that is not a meaningful local ranking. SchoolDigger gives it 4 stars and places it 253rd out of 1,126 Illinois schools, at the 78th percentile. Among the three subjects, ELA is its strongest relative result against the state, while science is its smallest state advantage. The all-grades results were 2 points below the district in ELA and 7 points below in math, though the reported grade-by-grade school and district results match.
Results rose in all three subjects from 2024–2025 to 2025–2026: ELA increased from 69% to 76%, math from 51% to 53%, and eighth-grade science from 62% to 64%. Mascoutah’s state advantage widened by 4 points in ELA and 1 point in math, but narrowed by 4 points in science. SchoolDigger’s percentile ranking also fell from the 89th percentile in 2023–2024 to the 78th in 2025–2026; that ranking is a separate measure from the test scores. The school’s 2024–2025 student-teacher ratio was 15.1:1, and 21% of students were reported as free/reduced lunch eligible that school year. Chronic absenteeism was 12% in 2025–2026, compared with 13% in the district and 24% statewide. With one school listed, the data cannot show how it compares with other nearby schools.
