Rose Glen Elementary is the standout of the group: it is the only five-star school here, ranking 101st of 1,039 elementary schools statewide (90th percentile), with the highest average proficiency in the ZIP at 75.9% and math scores of 80.95% to 84.93% in grades 3–5. West High is also a strong performer, ranking 75th of 533 high schools (86th percentile) with four stars; its graduation rate is 96.4%, its dropout rate is 0.0%, and all tested subjects in 2025–2026 beat district and state averages. Rose Glen's chronic absenteeism of 5.1% is by far the lowest locally, well under the district's 14.9% and the state's 17.3%.

Prairie Elementary is solid but trending downward. Its rank slipped from the 87th percentile to the 73rd, and its average test score fell from about 72.5% to 66.8%, with grade 4 math dropping from 79.55% to 60.66% and grade 5 math from 76.47% to 56.52%. It still outperforms state averages and has the smallest classes in the ZIP (13.2 students per teacher) and the highest spending ($14,372 per pupil). Mill Creek Academy is improving, moving from the 32nd to the 59th percentile over three years, but its results vary widely by grade and it has the highest free/reduced lunch rate (35.8%). Absenteeism is below the state rate at every school.
