Summary:
Zip code 83631 is served by a single high school, Idaho City High School, part of the Basin School District, operating as a small combined junior/senior high school serving grades 7 through 12 with 126 students, a favorable 10.9 student-teacher ratio, and 41.27% of students eligible for free/reduced lunch.
Academically, Idaho City High School has experienced a troubling decline in its statewide standing. The school's percentile ranking fell from the 53rd percentile (3 stars) in 2023–2024 to the 23rd percentile (1 star) in 2025–2026. While math proficiency improved from 26.7% to 31.0% and science from 25.0% to 30.6% over the past year, the school remains below state averages in every tested subject. English language arts proficiency fell dramatically from 58.3% to 45.1%, dropping below the state average of 54.0%. The largest gaps are in End of Course ELA (45.0% vs. 61.3% state), 8th grade math (28.6% vs. 41.2%), and 8th grade ELA (42.9% vs. 54.5%). In all grade-level and course tests, the school's scores trail Idaho statewide averages, with End of Course ELA showing the greatest shortfall at 16.3 points.
There are some noteworthy strengths. Chronic absenteeism sits at just 14.5%, far better than the district rate of 24.0% and nearly matching the state's 13.8%. The graduation rate of 82.5% exactly matches both district and state averages, though it still means about one in five students does not graduate on time. With only 126 students spread across six grade levels, the school offers a close-knit environment and a low student-teacher ratio that supports individualized attention. Per-student spending of $10,840 (2018–2019) suggests meaningful investment, yet academic outcomes continue to lag. For parents, Idaho City High School offers strong attendance engagement and a supportive small-school atmosphere, but the recent drop in literacy proficiency and the falling star rating are cause for careful consideration and possible targeted support.
