Westchester Elementary is a regular public school serving kindergarten through fifth grade in Kirkwood, Missouri. It is one of five elementary schools in the Kirkwood R-VII school district, the oldest district in St. Louis County. The school sits in an inner-ring suburb of St. Louis that was founded as the first planned residential commuter suburb west of the Mississippi River. Kirkwood’s original plat prohibited industrial development, reinforcing a residential character that persists today. The city has a compact historic downtown district with restaurants, shops, a farmers’ market, and a daily Amtrak stop at the landmark Kirkwood Train Station. The community is largely built out, with a stable population and high property values; the housing market in the school’s zip code reflects that affluence.
The district has made recent investments that affect Westchester families. In April 2025, voters approved a bond issue to fund capital improvements district-wide, including safety and security upgrades, HVAC replacements, and classroom additions, structured so that the debt service tax rate would not increase. That followed an earlier bond issue in 2021 that funded a new early childhood center, high school renovations, and district-wide safety upgrades. In November 2024, the school board adopted a new K-5 literacy curriculum for the 2025-2026 school year based on the science of reading, replacing the previous program. These are lasting changes that shape what happens inside Westchester’s classrooms.
The student body is predominantly white, with small shares of students who are Black, Hispanic, Asian, multiracial, or other races. A very modest share of students qualify for free or reduced-price lunch, reflecting the area’s high household incomes. Data on students with individualized education programs and English learners were not available in the records reviewed; a parent may want to follow up with the school directly on special education and language support services.
Academically, Westchester performs at a level that places it in the top quarter of all districts in St. Louis County on a combined proficiency index across tested subjects and grades. On the Missouri Assessment Program, the school’s proficiency rates in math show a pattern of declining performance from third grade through fifth grade, though each grade still reaches at least half of students scoring at the proficient or advanced level. In English language arts, third and fourth graders posted strong proficiency rates, and fourth grade was notably high. Fifth grade ELA results were suppressed and not reported. On the fifth-grade science assessment, a clear majority of students reached the proficient benchmark. The trend data available does not include prior years, so it is not possible to say whether these results represent improvement or decline over time.
Because Westchester serves only elementary grades, there is no graduation rate or college-and-career pathway data to report. Chronic absenteeism figures were also absent from the available records. Those gaps are typical for a K-5 school, but a family weighing the full K-12 experience in Kirkwood will want to look at the middle and high school outcomes separately.
The overall picture is of an elementary school with strong academic performance, set in a stable, affluent, and historically minded suburb whose school district is investing in facilities and curriculum. The student body is economically homogeneous. For a family who values high measured achievement in a low-poverty setting and is comfortable with the demographic makeup, Westchester fits that profile. Those who need more information on special education or English learner supports will need to reach out to the school, as those details were not available in the public data we examined.
