Summary:
The Troy School District is served by a single secondary school, Troy Junior/Senior High School, which enrolls 151 students in grades 7 through 12 in a small-town Idaho setting. The district is elite, ranking #6 out of 101 Idaho districts in the 94th percentile with a 5-star rating, while the school itself ranks #21 out of 122 Idaho high schools — an 83rd percentile, 4-star performance. This represents a major climb from its 3-star rating in 2012-2013, though the school appears to have peaked in 2022-2023 when it ranked #5 statewide.
Academically, Troy Junior/Senior High School outperforms the state across every tested subject. Science is the standout, with an 82.1% End-of-Course proficiency rate — nearly double the state average of 41.2%. ELA proficiency is similarly strong at 73.7% versus the state's 54.0%. Math is the relative weak spot: All-Grades math proficiency is 51.9% (above the state's 43.1%) but trails the district's 61.9% figure, suggesting stronger math performance in the district's earlier grades. The school also saw notable year-over-year declines from 2024-2025 to 2025-2026, with math dropping from 64.6% to 51.9% and ELA falling from 81.8% to 73.7%.
With a 12.8-to-1 student-teacher ratio and 33.8% of students qualifying for free or reduced-price lunch, the school delivers strong results despite serving a meaningful share of low-income families. However, its graduation rate of 82.5% sits exactly at the state average — a potential concern for a highly ranked school, though the small 151-student body means just a few students can swing the rate. Chronic absenteeism is 11.6%, better than the state's 13.8% but above the district's 9.0%. For parents, this school offers small classes, exceptional science and ELA instruction, and a top-10 district, though the recent test score declines and average graduation rate are worth monitoring.
