Original Research by School Decision on Estelle Kampmeyer Elem School
Estelle Kampmeyer is an early-grades public elementary school in O'Fallon, Illinois, serving prekindergarten through fifth grade. The school enrolls a small to mid-sized population, with enrollment spread across seven grade bands. The student body is predominantly white, with meaningful representation of Black, multiracial, Asian, and Hispanic students.
On the most recent state assessments, the school shows uneven proficiency across grade levels and subjects. In math, third graders perform above the school's median, while proficiency dips in fourth and fifth grades. English language arts tells a different story: third graders lag, but fourth and fifth graders perform notably stronger. In science, the fifth grade shows proficiency near the school's overall trend. The school participates fully in testing and maintains high participation rates. A caveat worth noting: Illinois changed its testing cut scores in recent years, which affects comparability to prior years, so year-to-year trends cannot be safely computed from this data.
When placed alongside other districts in St. Clair County, Kampmeyer's overall proficiency index sits in the top quartile, meaning the school performs above the median among its county peers. That distinction reflects solid academic standing, though parents may want to look into the grade-by-grade patterns more closely with the school, since performance is not uniform across grade levels.
The school sits in O'Fallon, a mid-sized suburban city in the Metro East region near Scott Air Force Base and about 18 miles from downtown St. Louis. The city has grown from its railroad and coal-mining roots into one of Southern Illinois' largest residential centers. It has a walkable historic downtown district anchored by Vine Street, with shops, restaurants, and weekly summer concerts, though most of the city is suburban and auto-oriented. Major civic anchors include a network of parks, the Family Sports Park with soccer and baseball fields, the O'Fallon Public Library at a civic plaza downtown, and the McKendree Metro Rec Plex. The city is investing in shared-use pathways to connect parks, schools, and trails. There is no local rail transit.
Housing in the area is moderately priced compared to national benchmarks. The median home value in the zip code is stable, and rents are climbing. First-time buyers can find entry-level homes in walkable neighborhoods near downtown and the older residential grids, while most newer neighborhoods consist of 1990s-2010s subdivisions and newer builder communities. Active listings are elevated, and the median days on market has been gradually increasing, suggesting a more balanced buyer-seller market than the prior year.
Families considering the district should be aware of recent property-tax changes. In early 2024, the District 90 Board approved a substantial working cash bond without a voter referendum, adding debt to be repaid through property taxes. Separately, the district has enacted successive large levy increases over 2023, 2024, and 2025, representing a compounding shift in the property-tax burden on homeowners. These changes are long-term commitments that affect the cost of owning a home in the district.
The school itself offers no data on special education enrollment, English learner enrollment, free or reduced-price lunch eligibility, teacher staffing levels, chronic absenteeism, or discipline. Information about course offerings, advanced programs, or school-specific initiatives was also not available. These are gaps worth filling through direct conversation with the school.
