Summary

Quincy Senior High School is a public school serving grades 9–12 in Quincy, Illinois, with 1,847 students in Quincy School District 172. Its clearest academic concern is 11th-grade ACT performance: in 2025–2026, proficiency was 39% in English language arts, 28% in math, and 39% in science—11, 12, and 9 points below state results, respectively, and below every nearby school with a reported score.

Results vary by grade and subject: 10th-grade science is a local bright spot, while 11th-grade ACT scores are below nearby reported results in every subject. Quincy’s 10th-grade science proficiency was 40%, third among five nearby schools and higher than Unity High School at 30% and Seymour High School at 32%, though still below the state’s 48%. Attendance is another concern: 40% of Quincy students were chronically absent in 2025–2026, compared with 24% statewide, 28% in the district, and about 11%–22% at nearby schools. Graduation was 83%, versus 90% statewide.

Recent results are mixed: 9th- and 10th-grade math proficiency rose between 2024–2025 and 2025–2026, but 11th-grade ACT ELA fell from 49% to 39% and math from 37% to 28%. Chronic absenteeism also declined, from 43% in 2021–2022, but remains high. SchoolDigger rates Quincy 402nd of 620 schools, at the 35th percentile and 2 stars, down from the 56th percentile the prior year; the district is at the 20th percentile and 1 star. Quincy is much larger than nearby schools and has a higher student-teacher ratio: 18.7:1 in 2024–2025, compared with a nearby-school average of 10.8:1. Its free/reduced lunch eligible share was 55% in 2024–2025, compared with a nearby-school average of 40%; these figures are context, not explanations for results. SchoolDigger’s rankings for how well the school serves Special Education Students and Multi-racial Students were especially low in 2025–2026, at the 5th and 3rd percentiles, respectively, compared with the school’s overall 35th percentile.
