Summary:
The high-school list for Sangamon Valley CUSD 9 contains one school, Sangamon Valley High School, serving grades 9–12 with 204 students.

As the area’s only listed high school, Sangamon Valley is both its sole option and the school with the standout results in the supplied data. Ninth-grade English language arts and science were bright spots: 76% were proficient in English versus 62% statewide, and 62% in science versus 47% statewide—about 15 percentage points above the state in each subject. Those results do not extend across all grades: grade 10 and grade 11 English and science results were below state figures. Completion and attendance measures were also favorable compared with the state: the 2025–2026 graduation rate was 100%, versus 90% statewide, and chronic absenteeism was 19%, versus 24% statewide.

Grade 10 was mixed, with math up 4 points and science up 6, but English down 1.
