Summary:
ZIP code 46738 in Garrett, Indiana contains one high school serving grades 9–12: Garrett High School, part of the Garrett-Keyser-Butler Com School Corp. With 553 students, a 12.7 student-teacher ratio, 40.14% free/reduced lunch participation, and $13,517 per-student spending in 2023–24, it is the only high school option in the area, so families here have a single public high school choice.
The school's clearest strength is completion: 99.3% of students graduated in 2024–25, well above Indiana's 89.7% rate. Test proficiency, however, tells a different story. In 2025–26, only 11.54% of 11th graders reached proficiency in SAT Mathematics, compared with 25.6% statewide, while SAT Evidence-based Reading and Writing came in at 41.54% versus 51.9% at the state level — a drop from 51.68% the prior year, when the gap to the state was only 2.82 points. ILEARN Biology improved from 24.27% in 2024–25 to 33.33% in 2025–26, though the 2024–25 state Biology rate was 45.6% and no 2025–26 state value is provided, so this gain should be viewed cautiously. Chronic absenteeism was 18.3%, higher than both the district (10.6%) and state (16.7%).
Rankings have drifted downward: 34th percentile in 2023–24, 31st in 2024–25, and 29th in 2025–26, with stars falling from 2 to 1 in the most recent year. The district itself ranks 268 of 374, at the 28th percentile with 1 star, and its graduation, Biology, SAT ERW, and SAT Math figures match the school exactly — likely because Garrett High School is the district's main high school. The takeaway for parents: graduation is strong, but math proficiency is persistently around half the state rate, reading slipped sharply, and absenteeism runs above both district and state levels. Parents should ask how the school plans to close the proficiency gap even as nearly every student graduates.
