The top reported proficiency rate is 90% in English language arts. The lowest is 78% in Science.
Original Research by School Decision on North Idaho Stem Charter Academy
North Idaho STEM Charter Academy sits on Rathdrum's western edge, serving students from kindergarten through twelfth grade on a single campus. As a public charter school, it operates under its own governing board rather than a traditional district, drawing families from across the Rathdrum area and the broader Kootenai County region who want a continuous K-through-12 STEM-focused education in one place.
The school's academic results on Idaho's ISAT assessments are a clear strength, particularly in mathematics. Across the elementary and middle grades, most tested cohorts show the large majority of students reaching proficiency, with several grades approaching near-universal proficiency. Science results at the tested elementary grade are similarly strong. English language arts starts strong in the early grades, with proficiency levels that rank among the higher results a parent would hope to see, but the picture grows more varied in the upper elementary and middle school years. Some grade-level results in ELA show wide reported ranges, and a parent may want to look into this further with the school to understand how literacy instruction is handled as students move into the later grades.
State testing data for the high school grades was not available in the provided materials. The school does serve a relatively small high school cohort, with enrollment tapering off after eighth grade, so some of the variability in reported results and the absence of certain high school metrics may reflect those smaller numbers. No graduation rate, advanced coursework, dual-credit, or career-pathway information was included in the data we received, so we cannot speak to those aspects of the upper grades.
The student body is predominantly white, with a small Hispanic population and smaller groups of Asian, multiracial, and other students. Free-or-reduced-price lunch data was not reported, nor were IEP or English-learner figures, so the economic and special-population composition of the school is not something we can characterize from what was provided. The total enrollment sits in the mid-range for a school covering this many grades, with fairly even distribution across the elementary and middle grades and a smaller high school section.
Rathdrum itself is a rapidly growing residential city in the Idaho Panhandle, sitting at the base of Rathdrum Mountain on the Rathdrum Prairie. It sits a short drive northwest of Coeur d'Alene and within easy reach of Spokane, Washington, at the junction of State Highways 41 and 53. The town has a historic downtown along Main Street with buildings dating to its late-nineteenth-century origins as a county seat and supply point for the Coeur d'Alene Mining District. Saint Stanislaus Church, the oldest brick church in Idaho, still stands there. Publicly reported sources describe Rathdrum as part of the Coeur d'Alene metropolitan area, and its population has grown substantially over recent census cycles as residential development spreads across the prairie. The BNSF Railway line runs through town, and the highway crossroads connect it to both northern Idaho and eastern Washington.
The housing market in the school's zip code runs well above the Idaho state benchmark and considerably above the national benchmark, with home values reflecting the broader growth pressure in the Coeur d'Alene area. Rents are moderate by comparison. A family considering this school should weigh the cost of housing in the Rathdrum area alongside the school's offerings, since the market here has been appreciating as the region draws new residents.
No comparison fact-set was provided to position this school against neighboring schools or districts, and the district brief returned little about recent changes or strategic priorities for the charter organization. What the available data does show is a school with a clear STEM identity, strong mathematics outcomes through the tested grades, solid early literacy results, and a continuous kindergarten-through-twelfth-grade pathway in a growing Panhandle community. The gaps in the record, particularly around high school outcomes, economic diversity, and special populations, are areas where a prospective family would benefit from asking the school directly.
