Summary:
Southwestern Con School Shelby County contains just one high school, Southwestern High School, a small combined middle/high school serving grades 7–12 with 264 students in Shelbyville, Indiana. Because Southwestern Con School Shelby County has only this one high school, all high-school analysis centers on it, and the school is naturally the standout in the area. It has a 12:1 student-teacher ratio, spent $12,738 per student in 2023–2024, and 43.18% of students qualified for free or reduced lunch in 2024–2025.
Southwestern High School's most striking feature is a dramatic turnaround in 2025–2026. It climbed from 305th of 429 schools (29th percentile, 1 star) in 2024–2025 to 112th of 415 (73rd percentile, 4 stars) in 2025–2026 — a jump of 193 rank positions from roughly the bottom third to the top third. Graduation is a clear strength at 97.6% in 2024–2025, equal to the district and well above the state's 89.7%. Reading and ELA are consistently strong: ELA All Grades reached 57.95% (above the district's 46.74%), 8th grade ELA hit 65.85% against a state rate of 44%, and SAT Evidence-based Reading and Writing was 57.69% versus the state's 51.9%. Biology End of Course produced the largest single-year gain in the data, rising from 7.89% to 52.83% (+44.94 percentage points).
Math is the clearest weakness. Math All Grades was 31.82%, below the district's 46.55%, and both 7th grade math (31.91%) and 8th grade math (31.71%) trailed state rates of 35.9% and 34.2%. SAT Math improved from 10% to 23.08% but still fell short of the state's 25.6%. Chronic absenteeism was 16.5%, essentially matching the state's 16.7% but 6.1 percentage points above the district's 10.4%, so attendance is worth monitoring. With only 264 students, percentages can swing widely from year to year, which is important context for the large Biology and ranking gains.
