Summary
Lewistown Junior/Senior High School serves 262 students in grades 7–12 in Lewistown, Illinois, and is part of Lewistown CUSD 97. Its results vary considerably by subject and grade: students have strong 9th- and 10th-grade PreACT English and science results, but weaker results in several other areas. The clearest concern is math, where Lewistown scored below the state in every reported grade-level assessment, from PreACT through the 11th-grade ACT.
Lewistown’s strongest results are in high-school English and science. On 9th-grade PreACT English, 67% were proficient, above the state’s 61.5% and the highest reported nearby-school result; 10th-grade English was also above the state and nearby schools. In science, Lewistown led nearby schools in both grades, with 56% proficient in 9th grade and 56% in 10th, respectively 9 and 8 points above the state. By contrast, 2025–26 all-grades IAR math proficiency was 12.5%, just below the district’s 13.4% and 27 points below the state’s 39.6%. Junior-high English is another concern: 8th-grade proficiency was 26%, 37 points below the state, while 7th grade was 42%, 15 points below. The supplied 11th-grade ACT results were also below the state in every subject.
There has been some recent IAR improvement, but the longer-term gap with the state has grown: from 2024–25 to 2025–26, Lewistown’s all-grades English rose 5 points and math rose 3 points, while both results remain further behind the state than in 2023–24. SchoolDigger ranks the school in the 56th statewide percentile, 270th of 620, with 3 stars—the highest standing among the nearby schools—and its percentile has risen 31 points since 2021–22. SchoolDigger’s group measure for how well the school serves Female Students reached the 70th percentile in 2025–26, up 21 points from the prior year; its White Students percentile was 34, 22 points below the overall result. For context, the 2024–25 student-teacher ratio was 11.9, and 49% of students were free/reduced lunch eligible. The 2025–26 graduation rate was 83%, down 7 points from the previous year and 7 points below the state; chronic absenteeism was 22%, close to the state’s 24% but above the district’s 18%.
