Oakville Elementary is a regular public school serving kindergarten through fifth grade in the Mehlville R-IX School District, located in the southern part of St. Louis County. The school sits in a residential area of the city, which is an independent city with a diverse economy anchored by major employers such as the Federal Reserve Bank of St. Louis, the National Geospatial-Intelligence Agency, Barnes-Jewish Hospital, and several research universities. The broader St. Louis area offers a range of cultural and civic institutions, including Forest Park, the Saint Louis Zoo, and the Missouri Botanical Garden.
The school’s enrollment is small for a K-5 building, and the student body is predominantly white. A modest share of students are from Asian, Black, Hispanic, or multiracial backgrounds. The share of students who qualify for free or reduced-price lunch is relatively low, indicating a student population that is, on average, economically well-off compared to many other public schools in the region. Data on the share of students with disabilities or who are English learners was not available.
Oakville Elementary’s academic performance on the Missouri Assessment Program (MAP) is a clear strength. In the most recent testing year, the school’s overall proficiency across tested subjects and grades placed it above the midpoint among districts in St. Louis County. In third grade, both math and English language arts proficiency rates were solid. Fifth grade results were also solid in math and English language arts, and science proficiency was strong. Fourth grade math proficiency was lower, and fourth grade English language arts results were suppressed, meaning the data was not reported, so a parent may want to ask the school directly about that grade’s performance. The school does not serve high school grades, so there is no graduation rate to report.
The school is part of the Mehlville R-IX School District. The district brief did not turn up any recent major changes such as a referendum, curriculum overhaul, or boundary shift, so a parent should check with the district office for any current developments.
Housing in the area around the school is moderately priced relative to the national market. Home values in the zip code are above the state benchmark but below the national benchmark. Rents are moderate, and the overall affordability picture suggests a market that is accessible for many families, though not inexpensive. The county housing market shows a modest increase in active listings and a slight decline in median listing price over the past year, with homes typically spending just over a month on the market.
For a family considering Oakville Elementary, the academic picture is the main draw. The school’s overall proficiency index sits above the midpoint among the districts in St. Louis County, a strong position. Third grade results in both math and English language arts were solid, and fifth grade results in math, English language arts, and science were all solid as well. Fourth grade math was a softer spot, and fourth grade English language arts data was suppressed, so a parent may want to look into this further with the school. The school does not serve high school grades, so there is no graduation rate to consider.
The student body is economically homogenous, with a relatively low share of students qualifying for free or reduced-price lunch. The school is not a charter or magnet school, and its Title I status was not reported. Data on chronic absenteeism, discipline, and staffing was not available, so a parent may want to ask the school about those areas directly. The school’s small size and elementary-only grade band mean the academic focus is on building foundational skills in a contained setting, with no high school pathways or graduation metrics to evaluate. For a family looking for a solid-performing elementary school in a stable, middle-market part of St. Louis County, Oakville Elementary presents a straightforward option with clear academic strengths in the early and upper elementary grades.
