Summary:
O Fallon CCSD 90 has five elementary schools serving PK–5 or K–5, with enrollments from 421 to 598 students. In 2025–26, the five-school averages were 68% in all-grades ELA, 61% in all-grades math, and 66% in grade 5 science, compared with state rates of 56%, 40%, and 48%. The most important takeaway is that every school exceeded the state rate in these subjects, but school results still varied substantially.
Delores Moye Elementary School led all-grades ELA at 74%, while J Emmett Hinchcliffe Senior Elementary School narrowly led math at 67.9%, just 0.3 points above Delores at 67.6%. At the other end, Laverna Evans Elementary School scored 58% in ELA and 50% in math—the lowest in the group, 17 points below the ELA leader and 18 points below the math leader. Estelle Kampmeyer Elementary School led grade 5 science at 72%; Marie Schaefer Elementary School was lowest at 60%. Leaders also shift by grade: Delores leads grade 3 ELA and math, while Kampmeyer leads grade 4 and grade 5 ELA.
Recent changes were mixed: the average ELA score rose 3 points from 2024–25 to 2025–26, while math edged down by less than a point; the average lead over the state narrowed in both subjects. Science rose 7 points on average, including a 29-point increase at Evans, which ranked second in science despite its lower ELA and math results. SchoolDigger gives Delores an 86th-percentile ranking and four stars, compared with Evans at the 61st percentile and three stars. For context, 2024–25 free/reduced lunch eligible shares ranged from 20% at Hinchcliffe to 42% at Evans; student–teacher ratios ranged from 14.5 at Delores to 20.0 at Evans. These measures describe school contexts, not explanations for test results.
