Summary:
Caston Junior-Senior High School is the only high school in Caston School Corporation, serving 435 students in grades 6–12 in Rochester, Indiana. Because it is a combined junior-senior high, its ILEARN results largely reflect middle-school grades (6–8), while its SAT, Biology End-of-Course, and graduation data reflect high school performance — an important distinction when reading its results. The student body has a relatively high free/reduced lunch rate of 60.69%, a student-teacher ratio of 12.7, and per-student spending of $12,372.
The school's clearest strengths are in science, graduation, and attendance. Sixth-grade ILEARN Science proficiency is 52.17%, about 11 points above the state's 41.2%, and Biology EOC proficiency is 59.62% in 2025–2026 and 59.46% in 2024–2025 — well above the 2024–2025 state rate of 45.6%. The graduation rate is 94.5%, above the state's 89.7%, and chronic absenteeism is 14.3%, better than the state's 16.7% but higher than the district's 12.0%. Math also improved, with all-grade proficiency rising from 36.78% to 40.63%, and grades 6 and 7 now above state benchmarks. SAT scores improved year over year in both Evidence-based Reading and Writing (30.19% to 36.76%) and Math (11.32% to 16.18%), and the school's rank moved from 242 of 429 to 228 of 415.
Challenges remain in English language arts and high-school readiness. All-grade ELA fell from 45.4% to 40.21%, and grades 6, 7, and 8 all sit below their state benchmarks. SAT results are still well below state: 36.76% in ERW versus 51.9%, and 16.18% in Math versus 25.6%. Eighth-grade Math (30.36%) is also below the state's 34.2%. The overall rating dropped from 4 stars in 2023–2024 to 2 stars in both later years, even as the district sits at the 53rd percentile with 3 stars. Overall, science, biology, graduation, and attendance are relative strengths; ELA, SAT performance, and the school's rating are the areas to watch.
