Summary:
Zip code 83530 in Grangeville, Idaho, is served by two schools in the Mountain View School District: Grangeville Elementary/Middle School, serving grades PK-8 with 505 students, and Grangeville High School, serving grades 9-12 with 244 students. The district ranks 56th out of 101 Idaho districts, putting it in the middle of the pack statewide.
Grangeville High School is the clear standout in this area. It ranked 7th out of 112 Idaho high schools in 2024-2025, a 94th-percentile, five-star performance. Although it dropped to 39th of 122 schools in 2025-2026, it remains in the 68th percentile. That year the school posted exceptional ISAT results, with 82.9% ELA proficiency and 73.8% science proficiency — roughly 30 points above state averages. It also benefits from a 15.3:1 student-teacher ratio, roughly $15,000 in per-student spending, and a chronic absenteeism rate of 12.5%, better than the state's 13.8%. Its graduation rate of 82.5% matches both the district and state exactly.
Grangeville Elementary/Middle School presents a more mixed picture. It ranked in the 36th percentile in 2025-2026, a modest improvement from the 23rd percentile the previous year. The school shows genuine strengths in early-grade reading — 3rd grade ELA proficiency reached 59.6%, more than 11 points above the state — and it outscored the state in 5th, 7th, and 8th grade ELA as well. Math, however, is a clear weakness: overall math proficiency is 36.1%, seven points below the state average, with 4th grade a particularly large 18-point deficit. The school also faces more challenges than its high school counterpart, with 47.5% of students eligible for free/reduced lunch versus 32.4% at the high school, and chronic absenteeism of 14.9%, slightly above the state. Its 6th grade ELA score of 35.4% is a striking outlier worth monitoring.
