Summary:
ZIP code 47387 has just one high school: Tri Junior-Senior High School, a combined junior-senior high serving grades 6–12 with 458 students, located in Straughn and part of the South Henry School Corp. Because it is the only school in the area, parents should compare it mainly to its own district and to Indiana averages.
The school's strongest results are in completion and attendance. Its 2024–2025 graduation rate is 100%, matching the district and 10.3 percentage points above the state's 89.7%. Chronic absenteeism is 8.2%, below the district's 9.8% and far below the state's 16.7%. Its ranking also improved, moving from 1 star and a percentile of 16 in 2023–2024 to 2 stars and a percentile of 35 in 2024–2025, then settling at 2 stars and a percentile of 31 in 2025–2026. The district itself holds a 1-star rating and a percentile of 27, though the school and district rankings come from different lists.
Academic proficiency is the weaker side of the picture, especially in math. All-grades ILEARN math is 21.28% in 2025–2026 and 20.73% in 2024–2025, well below the district's 32.2% and 31.13%. Seventh-grade math is 8.33% against the state's 35.9%, eighth-grade math is 21.21% versus 34.2%, and SAT math is 14.81% versus 25.6%. ELA is mixed: all-grades ELA edges above the district, but grade-level results and SAT reading and writing trail the state. Science and biology also lag, with Biology End of Course at 21.57% in 2025–2026 and 24.07% in 2024–2025 against a state figure of 45.6%. Context matters here: about 49.78% of students qualify for free or reduced lunch, per-student spending is $10,361, and the student-teacher ratio is 14:1.
