Original Research by School Decision on Westhoff Elem.
Westhoff Elementary serves kindergarten through fifth grade in the Fort Zumwalt School District and sits in O'Fallon, Missouri, St. Charles County’s most populous suburb. O’Fallon is a largely auto-oriented community of residential subdivisions and commercial corridors along Interstates 64 and 70, with a mix of major employers such as Mastercard and True Manufacturing and an extensive parks and sports complex system. The city has seen steady suburban growth over the past two decades. Westhoff is one of many elementary schools distributed across the district, which covers most of O’Fallon. No major, parent-relevant changes were publicly reported for the district in recent years.
The school enrolls roughly five hundred students across kindergarten through fifth grade, with each grade level holding a similar-sized cohort. The student body is predominantly white, with smaller shares of Black, Hispanic, Asian, and multiracial students. About a fifth of students qualify for free or reduced-price lunch, a rate that places the school on the lower end of economic need relative to many districts in the region. Data on students with disabilities and English learners were not available; a parent may want to ask the school directly about those supports.
On state assessments, the Missouri Assessment Program, Westhoff’s results present a mixed picture. In mathematics, the share of students scoring proficient or advanced rose from grade three to grade four, then held steady at about half in grade five. In English language arts, proficiency was below half in grade three, reached roughly half in grade four, and was above half in grade five. In fifth-grade science, about half of students met the proficiency bar. Across all tested subjects and grades, the school’s overall proficiency index placed it in the bottom quartile relative to the other districts in St. Charles County. That comparison is based on a set of five districts, so the range is narrow, but Westhoff sits below the midpoint of that group. Because the school only serves elementary grades, there is no graduation rate to report.
No data was available on course offerings, staffing ratios, discipline rates, or chronic absenteeism, so those dimensions cannot be assessed here. Westhoff is a regular public school, not a charter or magnet, and its Title I status was not indicated.
Housing in the area is relatively expensive. Home values and rents in the ZIP code are above the state median and close to the national median, reflecting the broader St. Louis suburban market. The estimated monthly mortgage payment for a median-priced home is substantially higher than the typical rent, suggesting that buying is less accessible than renting for many households.
For families considering Westhoff, the school sits in a suburban context with a solid economic base and a district that serves a large, spread-out community. The academic performance is not at the top of the county’s districts, and the variation by grade and subject suggests that some cohorts may be stronger than others. Parents who place a premium on test scores may want to investigate how the school supports students who are not yet proficient and what enrichment is available for those already meeting the bar. Because Westhoff feeds into Fort Zumwalt middle and high schools, the full academic pathway matters as much as the elementary years themselves.
