Prairie Junior/Senior High School

Prairie Junior/Senior High School is a small, combined junior/senior high school serving 204 students in grades 7–12 in Cottonwood, Idaho, and it sits within the Cottonwood Joint District—one of the top-ranked districts in the state at 7th out of 101 Idaho districts. The school itself earned a 19th-place ranking among Idaho high schools for 2025–2026, a strong rebound from the previous year and consistent with its historical performance. Prairie students post impressive test scores: 71.7% proficiency in English language arts, 58% in math, and 49.3% in science, all well above state averages.

Compared with nearby Grangeville High School, about 15 miles away, Prairie stands out in several key areas. On the most recent end-of-course exams, Prairie outperformed Grangeville in science (59.4% vs. 45.3% proficient) and English language arts (74.2% vs. 66.7%). Prairie also has dramatically lower chronic absenteeism at just 4.7%, compared with Grangeville's 12.5% and the state average of 13.8%. The two schools serve somewhat different populations—about 21.6% of Prairie students qualify for free or reduced-price lunch versus 32.4% at Grangeville—and Prairie achieves its strong results while spending about $3,000 less per student. Both schools have small class sizes, with Prairie's student-to-teacher ratio of 14.6:1 slightly more favorable than Grangeville's 15.3:1.

There are a couple of areas worth watching. Prairie's graduation rate has declined from a peak of 97.4% in 2021–2022 to 82.5% in 2024–2025, which now matches the state average. Additionally, internal data shows a notable drop in test proficiency between 7th and 8th grade—from 72.7% to 45.7% in math and 78.8% to 62.9% in ELA—which may reflect a challenging transition year or simply a particularly strong 7th-grade cohort. Overall, Prairie is a reliably strong rural school with excellent attendance, top-tier district support, and a record of high achievement. If it can stabilize graduation rates and better understand the middle-grade dip, it should remain one of Idaho's better-performing small high schools.
