Summary:
Zip code 83854 in Post Falls, Idaho, is served by eight schools spanning pre-kindergarten through 12th grade, including five elementary schools, one middle school, one high school, and one alternative academy, with a total enrollment of roughly 3,283 students. Six of these schools belong to the Post Falls District, which ranks 34th out of 101 Idaho districts (3 stars), while the other two are independent charter/alternative options. The clear academic leader is Greensferry Elementary School, a 4-star school ranked 44th in the state with 68.2% math and 67.2% ELA proficiency, far exceeding state averages and posting the lowest chronic absenteeism (8.1%). Other district elementary schools like Prairie View Elementary and West Ridge Elementary School perform near or above state averages, while Mullan Trail Elementary School lags in ELA (49.2%) despite high spending.
The alternative schools present a stark contrast. Kootenai Classical Academy shows exceptional early grades—75.9% math proficiency in 4th grade—but collapses to 33.3% by 5th grade and 29.2% by 8th, suggesting a serious upper-grade challenge. Treaty Rock Elementary is a turnaround story, jumping from the 29th to 51st percentile in one year with a 9.4-point ELA gain. Meanwhile, Elevate Academy North is the most concerning outlier: only 8.2% math and 24.4% ELA proficiency, a 38.9% chronic absenteeism rate, and the highest poverty rate (50.3% FRL), even though its graduation rate matches the state average at 82.5%.
Chronic absenteeism closely tracks achievement—Greensferry leads both categories, while Elevate Academy sits at the bottom. Notably, resources don't predict results: Mullan Trail spends the most per student ($8,185 yet ranks in the 43rd percentile, and Elevate Academy has the lowest student-teacher ratio (13.2) but the worst academics. The middle school transition appears difficult, as River City Middle School's 6th grade math proficiency (39.4%) drops sharply below the 5th grade scores of its feeder elementary schools like Greensferry (64.5%). For parents, this zip code offers excellent options anchored by Greensferry, but significant variation in school quality, attendance, and grade-level performance means careful school choice matters.
