Summary
Centerton Elementary School is a small PK–4 school in Martinsville, IN, serving 126 students as part of MSD Martinsville Schools in a suburban-to-rural area southwest of Indianapolis. The headline for parents is volatility. Centerton ranked 431st of 1,015 Indiana schools in 2025-2026 (58th percentile, 3 stars) — above its district’s percentile, but well below where it sat just two years earlier, when it ranked 11th of 1,011 in 2023-2024 (99th percentile, 5 stars) and 80th of 1,005 in 2024-2025 (92nd percentile, 5 stars). With only about 126 students, a handful of children can move these percentages sharply, so a single year is worth watching rather than over-reading.
Academically, math is Centerton’s clearest strength. All-grade math proficiency was 60.78%, well above the district’s 38.73%, and both 3rd grade (57.89%) and 4th grade (62.5%) beat district and state averages. English language arts is mixed: 41.18% overall, above the district, with 3rd grade strong at 52.63% but 4th grade at 34.38% — above district yet below the state. Science is the weakest area at 34.38%, below both district (43.69%) and state (43.8%). By comparison, Green Township Elementary School — same district, similar size, PK–4 — outperforms Centerton in ELA, math, and science. Still, Centerton’s math beats most nearby schools, including Brooklyn STEM Academy, Charles L Smith Fine Arts Academy, South Elementary School of Communications, and Poston Road Elementary School.
Attendance is a genuine institutional strength: chronic absenteeism has held near 11% for years, far below district and state rates, and lower than nearly every nearby school. Two headwinds are worth monitoring. The free/reduced lunch rate climbed from 33.05% to 52.38% in two years, and the student-teacher ratio rose from 15.7 to 20 — the highest among the nearby schools compared here. Per-student spending of $11,966 is mid-range, and Centerton outranks some higher-spending peers, so money alone doesn’t explain results. Overall, this is a small, attendance-strong, math-strong school that still beats its district in ELA and math, with science and 4th-grade ELA as the areas to ask about.
