Summary:
Zip code 82501 has six schools serving 2,181 students, from elementary through high school: three elementary schools, one middle school, and two high schools, all in Fremont County School District #25. Across the available 2025–2026 results, schools averaged below state proficiency in English, math, and science, with science showing the largest average gap (10.6 percentage points below). But results vary sharply by school and grade: the most important finding is the wide elementary-school divide, especially in grade 5, where the strongest-to-weakest gaps reached 33.5 points in English and 36.6 in math.
Rendezvous Elementary leads in several upper-elementary results: its grade 5 English proficiency was 71.6%, 10.3 points above the state, and its grade 4 and 5 math results were 63.8% and 65.2%. Willow Creek Elementary also has bright spots, including grade 3 English at 58.0% and grade 5 English at 69.8%. At the other end, Aspen Elementary School was far below the state in grade 4 English and grade 5 math: 26.4% and 28.6%, respectively. Riverton Middle School stands out in grade 6 and 7 math, exceeding state results by 6.3 and 6.1 points. Riverton High School also topped state results in grade 10 English and math, while Frontier Academy reported under 10% in all three grade 10 subjects.
Recent changes are mixed rather than consistently upward: across 24 matched school-and-subject results, the average gap from state results widened slightly by 1.1 points, though Riverton Middle School improved its grade 6 math gap by 12.8 points, while Willow Creek Elementary’s grade 4 science gap worsened by 15.5. SchoolDigger’s statewide percentile rank rose for Riverton High School from 20 in 2023–2024 to 40 in 2025–2026, but fell for Rendezvous Elementary from 62 to 33. Reported student–teacher ratios range from 10.2 at Aspen Elementary School to 16.4 at Riverton High School; the elementary schools’ reported free/reduced-lunch eligibility ranges from 39.0% at Willow Creek to 47.8% at Rendezvous, observations that do not by themselves explain achievement. Results vary in year and grade coverage, and Frontier Academy’s under-10% figures are bounds rather than exact scores.
