Summary:
Porter Township School Corp contains a single high school, Boone Grove High School, which serves grades 9–12 in Valparaiso, Indiana, with an enrollment of 467 students. Because it is the only high school in the district, the most useful comparisons are against Indiana averages and against the school's own prior-year results. The school reports a 12.9 student-teacher ratio, 27.19% free/reduced lunch participation, and $13,266 in per-student spending for 2023–24.
Boone Grove's strongest results are in completion and engagement. Its district is ranked 52 of 374 in Indiana — the 86th percentile, with 4 stars — and the school's own rank has climbed from 136 of 432 in 2023–24 to 85 of 415 in 2025–26, moving from 3 stars to 4 stars and rising from the 69th to the 80th percentile. The 2024–25 graduation rate was 97.7%, well above the state's 89.7%. Chronic absenteeism was 9.9%, far below the state's 16.7%, though slightly above the district's 8.2%.
Test scores tell a more mixed story. SAT Evidence-based Reading and Writing dropped from 70.97 in 2024–25 to 51.89 in 2025–26, moving from 16.47 points above the state to essentially tied with it (51.9). SAT Mathematics fell from 35.48 to 23.58, moving from 10.08 points above the state to 2.02 points below it (25.6). Biology moved the other way, rising from 32.73 to 68.63; no state Biology value is provided for 2025–26, so that score cannot be state-benchmarked. Overall, this is a school with strong completion and engagement metrics and an improving rank, offset by a sharp recent SAT decline.
