Summary:
ZIP code 83855 is served by one high school, Potlatch Junior/Senior High School, which enrolls 209 students in grades 7 through 12 in the rural community of Potlatch, Idaho. The school has shown impressive momentum in recent years, climbing from the 35th percentile statewide in 2023–2024 to the 65th percentile in 2025–2026, a move that earned it a three-star rating. This improvement stands out even more because its district, Potlatch District, ranks only in the 40th percentile overall, meaning the high school is performing above the district's average statewide standing.
Academically, Potlatch Junior/Senior High presents a split picture. At the high school level, End-of-Course exams exceed state averages in math, science, and English language arts. However, 7th and 8th grade scores lag well behind the state, particularly in 8th grade math (25.8% vs. 41.2%) and ELA (43.8% vs. 54.5%). Overall all-grades proficiency still trails the state in math (35.4% vs. 43.1%), science (38.9% vs. 42.7%), and ELA (48.5% vs. 54.0%), but the school leads its district in science and ELA. A bright spot is math: proficiency jumped nearly 10 points in one year, from 25.8% to 35.4%.
The main areas of concern are chronic absenteeism and graduation. At 16.9%, chronic absenteeism is significantly higher than the district (10.4%) and state (13.8%), which can hinder learning. The graduation rate of 82.5% matches the state average, meaning about one in six students does not graduate on time. With a relatively low free/reduced lunch rate of 33.5% and a student-teacher ratio of 14.5:1, the school has a solid foundation. Overall, Potlatch Junior/Senior High is a school moving in the right direction, especially for high school students, but focusing on middle-grade support and attendance could unlock further gains.
