Summary:
Zip code 62366 has one high school, Pleasant Hill High School, serving grades 9–12 with 99 students. The school’s reported graduation rate is 79%, compared with 90% statewide, while chronic absenteeism is 22%, slightly below Illinois’s 24%. Its clearest current academic strength is 11th-grade ACT science: 61% proficient, 13 percentage points above the state.
With only one high school in the area, there is no local school-to-school top or bottom; the strongest and weaker results are within Pleasant Hill’s own profile. In 2025–2026, science was 13 points above the state, while ELA was 48% proficient compared with 50% statewide, a 2-point shortfall. The school’s current math result is suppressed, so its standing in that subject is unknown. Earlier, 2024–2025 PreACT results were below state rates in all six reported grade-and-subject comparisons, with gaps ranging from 2 to 22 points. The graduation rate’s 11-point gap from the state is another area to note, while absenteeism was 1 point lower than the state figure.
Recent 11th-grade ACT results show marked improvement in science and a smaller gain in ELA: science rose 19 points, from 42% to 61%, while the state rate fell 1 point; ELA rose 6 points, from 42% to 48%, as the state fell 2 points. The school’s science position shifted from 7 points below Illinois to 13 points above, and its ELA shortfall narrowed from 10 points to 2. SchoolDigger’s reported percentile also rose from 35 to 60 to 71, though its ranked comparison group changed in size. As context, 58% of students were free/reduced lunch eligible in 2024–2025, and the student–teacher ratio was 8.6. These figures describe the school but do not explain its results; with just one school, they cannot show how these characteristics compare across local schools.
