Summary:
ZIP code 47929 covers Chalmers, Indiana, and contains exactly one school: Frontier Junior-Senior High School, a high school serving grades 7–12 with 270 students, part of the Frontier School Corporation. Because it is the only school in the ZIP, there is no second local school to compare against, so the most useful benchmarks are the district and the state.
The school's current profile is strong. In 2025–2026 it ranked 72nd of 415 schools — the 83rd percentile, earning 4 stars — after a 2024–2025 dip to 236th of 429 (45th percentile, 2 stars) and a 2023–2024 result of 121st of 432 (72nd percentile, 4 stars). Its 2024–2025 graduation rate was 97.5%, well above Indiana's 89.7%, and chronic absenteeism was 6.7%, below the district's 11.4% and less than half the state's 16.7%. Reading is a consistent strength: all-grades ILEARN ELA was 52.33% against the district's 42.14%, 7th- and 8th-grade ELA ran roughly 9–10 points above state, and SAT Evidence-based Reading and Writing was 58.7% versus 51.9% statewide. SAT Math jumped from 11.9% in 2024–2025 to 41.3% in 2025–2026, far above the state's 25.6%.
Math is the area to watch. All-grades ILEARN Math was 38.37%, below the district's 44.82%, and 7th-grade Math (34.69%) was slightly below the state's 35.9%, though 8th-grade Math (43.24%) beat the state's 34.2%. With 270 students and a student-teacher ratio of 11.2, small grade-level and SAT cohorts can make year-to-year swings large. Per-student spending was $13,940 (2023–2024) and 30.74% of students qualified for free/reduced lunch (2024–2025), but no district or state comparison was provided, so those figures are context only. Some state comparisons, including all-grades ILEARN and 2025–2026 Biology, were not provided.
