Cascade Senior High School is a public high school serving grades 9–12 in Clayton, IN, with 537 students in the Mill Creek Community School Corp. It is rated 70th of 415 Indiana high schools in 2025–2026 — 83rd percentile, 4 stars — while its district ranks 31st of 374 districts, 92nd percentile, 5 stars. The school was a 5-star school in several earlier years and has been at 4 stars since 2022–2023. Graduation rates are excellent: 97.6% in 2024–2025 versus the state’s 89.7%. Chronic absenteeism is 11.3%, below the state’s 16.7%, though higher than the district’s 7.5%.
Academically, Cascade Senior High School shows a clear split: strong reading and weaker math. Its SAT Evidence-Based Reading and Writing score is 71.32%, the second-highest among nearby schools behind only Brownsburg High School at 75.78%. SAT math is 27.13%, only 1.5 points above the state’s 25.6% and far below top nearby schools, which score in the low-to-mid 40s. Biology ILEARN End-of-Course is 52.31%, down from 63.7% the prior year and below the district average of 57.08%. Compared with Danville Community High School, graduation, attendance, and Biology are very similar, but Danville’s SAT math is 41.41%, making math the clearest gap.
Among nearby schools, Cascade Senior High School outperforms Mooresville High School, Monrovia High School, and Eminence Junior-Senior High School, but trails Brownsburg High School, Tri-West Senior High School, Plainfield High School, Avon High School, and Danville Community High School. Resources do not look like the obvious hurdle: its 13.7 student-teacher ratio is the second-lowest nearby after Eminence Junior-Senior High School, and spending is $11,508 per student, below the nearby median. Its free/reduced lunch rate of 25.88% is lower than most peers except Tri-West Senior High School, so the math lag is not explained by higher poverty. Reported major student subgroups are all rated 4 stars, with special education improving substantially. Overall, this is a solidly above-average school with strong graduation, attendance, reading, and subgroup results; the main improvement areas are math and the recent Biology decline.
