Sangamon Valley CUSD 9


Summary:

The Sangamon Valley CUSD 9 district in Illinois serves students from preschool through 12th grade across 4 schools: 2 elementary schools, 1 middle school, and 1 high school. While the district faces challenges with high chronic absenteeism and economic disadvantage, one school stands out as a top performer - Sangamon Valley Intermediate School.

Sangamon Valley Intermediate School is the highest-performing school in the district, with the best proficiency rates on state assessments in both English Language Arts (65.2%) and Mathematics (53%). The school also holds a 4-star rating from SchoolDigger, the highest in the district. In contrast, Sangamon Valley High School has seen a decline in its statewide ranking, dropping from 235 out of 697 Illinois high schools in 2023-2024 to 460 out of 698 in 2024-2025.

Across the district, high rates of chronic absenteeism, ranging from 25.4% to 25.4%, and free/reduced lunch eligibility, from 59.79% to 66.91%, suggest equity concerns and the need for the district to address these challenges. While student-teacher ratios are relatively low, the inconsistent performance across schools indicates that the district should focus on improving academic outcomes, particularly at the middle and high school levels.
