Summary:
Zip code 62257 has one listed high school, Marissa Junior & Senior High School, serving grades 7–12 and enrolling 226 students. Its latest all-grades results are mixed: in 2025–26, English Language Arts proficiency was 60%, 4 percentage points above Illinois, while math proficiency was 27%, 13 points below the state. Graduation was 89%, close to the state’s 90%, and chronic absenteeism was 16%, 7 points below the state’s 24%. With only one school listed, there is no meaningful local school-to-school comparison. The clearest takeaway is that Marissa’s ELA results exceed the state average, but its all-grades math results fall well short.
Marissa’s strongest reported comparisons are in 8th grade, while its largest shortfalls are in 11th grade. In 2025–26, 8th-grade science proficiency was 66%, versus 52% statewide, a 14-point advantage; 8th-grade ELA was 75%, versus 63%, a 12-point advantage. By contrast, 11th-grade ACT science was 29%, versus 48% statewide, and 11th-grade ACT ELA was 31%, versus 50%—19 points lower in each subject. Since Marissa is the only school in the list, it is both the local high and low; these differences show how much results vary by grade and subject, not which local school is best.
Recent results moved in different directions: from 2024–25 to 2025–26, all-grades ELA fell from 67% to 60%, narrowing its state advantage from 14 points to 4, while math rose from 23% to 27% and its state shortfall narrowed from 16 points to 13. Science also diverged by grade: 8th-grade results rose 12 points, while 11th-grade ACT science fell 15 points. SchoolDigger reports a 2025–26 rank of 420 out of 620 Illinois schools, at the 32nd percentile and 2 stars; its 2024–25 standing was the 63rd percentile, a decline of 31 percentile points, though the ranking pools differed. The school’s 9.8 student–teacher ratio and 60% free/reduced lunch eligible measure are from 2024–25 and provide context, not explanations for results.
