Summary:
Zip code 83877 contains one public middle school, Post Falls Middle School, serving grades 6–8 with 746 students in the Post Falls District.
Post Falls Middle School is the only middle school in this zip code, so it serves as the primary middle-level education provider for the area. The school shows a clear strength in English Language Arts, with 61.6% proficiency in 2025–2026, outperforming both the district (58.6%) and the state (54.0%). Science is also a hidden strength, as 8th graders posted a 49.4% proficiency rate, exceeding the state average by 6.5 points. However, math is more of a challenge, with 43.2% proficiency matching the state average but trailing the district's 45.8%.
Breaking down math by grade, 7th graders stand out with 47.7% proficiency—well above the district and state—while 6th and 8th graders fall to 40.7% and 41.5% respectively. ELA proficiency improves steadily from 61.0% in 6th grade to 62.3% in 8th grade, a positive sign for literacy development. The school has consistently earned 3 stars from the state, with its percentile ranking rebounding from the 53rd percentile in 2024–2025 to the 64th percentile in 2025–2026. Chronic absenteeism sits at 12.1%, slightly above the district's 12.0% but below the state's 13.8%, and about 38.6% of students are eligible for free or reduced-price lunch.
The most notable takeaway is the gap between subjects: ELA proficiency is 18.4 points higher than math. Rank improvement in 2025–2026 appears driven largely by strong ELA gains, while math remains an area for intervention, especially in 6th and 8th grades. Overall, Post Falls Middle School offers a solid academic experience with clear strengths in literacy and science, but families should be aware that math performance is only average compared to state peers.
