Summary:
Henry-Senachwine CUSD 5 has one high school, Henry-Senachwine High School, serving grades 9–12 with 147 students. Its 2025–2026 results are mixed by subject: English language arts (ELA) is above Illinois results where scores are available, while math is below state levels in both grades with reported results. The sharpest concern is 10th-grade science, where proficiency was 18 percentage points below the state.
Henry-Senachwine High School’s strongest relative results are in 9th-grade science and ELA: science proficiency was 58%, compared with 47% statewide, and ELA was 66%, versus 62%. Its 11th-grade ELA result was also higher than the state’s, 55% to 50%. By contrast, 10th-grade science was 30% proficient versus 48% statewide; math was also lower than state results in 9th grade (37% versus 42%) and 11th grade (30% versus 40%). The 11th-grade science result was close to the state’s (48.5% versus 47.9%). The graduation rate was 85% compared with 90% statewide, while chronic absenteeism was 22% versus 24% statewide.
Results improved overall against the state across six comparable grade-and-subject measures, but the changes varied: the average gap shifted from about 3 points below the state in 2024–2025 to about 1 point above in 2025–2026. Ninth-grade results rose notably, including ELA from 51% to 66% and math from 21% to 37%; however, 11th-grade math fell from 33% to 30%, and science fell from 60% to 49%. SchoolDigger’s ranking rose from 527th of 697 schools (24th percentile) in 2023–2024 to 272nd of 620 (56th percentile) in 2025–2026. Other context for families: the student-teacher ratio was 8.3 in 2024–2025, and 47% of students were free/reduced lunch eligible that year. With only one high school in the list, there is no school-to-school comparison; the 10th-grade ELA and math results were suppressed.
