Best Middle Schools in Zip Code 83805

Zip code 83805 is served by a single public middle school, Boundary County Middle School, which enrolls 336 students in grades 6 through 8 in Bonners Ferry, Idaho, and operates within the Boundary County District. Because it is the only middle school in the area, it is the clear standout by default, but it also stands out for its strong academic performance. Math proficiency is a notable strength: 56.4% of all students are proficient in math, compared to 43.1% statewide, and 8th grade math reaches 61.6% proficiency, a remarkable 20.4 percentage points above the state average. The school also posts strong 8th grade English Language Arts results, with 64.6% proficiency versus 54.5% statewide.

Consistency is another hallmark of this school. It has earned a 4-star rating in each of the past three school years and ranked in the 73rd, 70th, and 75th percentiles respectively, improving its position in 2025–2026 despite more schools being added to the comparison. Overall ELA proficiency of 59.6% and all-grades math of 56.4% both exceed district and state averages. However, the school’s chronic absenteeism rate of 23.1% is dramatically higher than the district rate of 13.6% and the state rate of 13.8%, meaning nearly one in four students is chronically absent. Additionally, 7th grade ELA proficiency of 54.3% is the one tested area that falls below the state average of 56.8%, suggesting a targeted area for intervention.

In prior-year testing, science proficiency was 46.7%, slightly above the state average of 42.6% but below the district average of 50.9%. About 42% of students qualify for free or reduced lunch, reflecting a moderate poverty rate, yet the school still maintains above-average academic results. With a student-teacher ratio of 18:1, class sizes are reasonable and may support the strong math outcomes. The most recent spending data from 2018–2019 shows $9,688 per student, though more current figures would be needed for a full funding picture. Overall, Boundary County Middle School is a solid, above-average school with exceptional math performance and consistent 4-star ratings, with its primary challenge being chronic absenteeism and a slight dip in 7th grade ELA.
