Original Research by School Decision on Delores Moye Elem School

Delores Moye Elementary is a school serving early grades through fifth in O'Fallon, a mid-sized suburban city in the Metro East region of greater St. Louis, about five miles from Scott Air Force Base. The school enrollment sits in the mid-range for an elementary school of this grade span, with a diverse student body; the largest group identifies as white, with sizable African American, multiracial, and Hispanic populations represented.

The most recent state assessment data shows uneven performance. In English language arts, third graders reached proficiency at a solid rate, and fourth graders also performed at a reasonable level. By fifth grade, proficiency slipped measurably lower in ELA, though it remained above half the cohort. Math proficiency started stronger in third grade but declined noticeably in fourth and fifth, with fifth-grade math proficiency falling to around two-thirds of tested students meeting the state standard. Science proficiency in fifth grade, the only grade tested in that subject, fell notably below the ELA and math results. Taken together, the school shows strength in the earliest grades and measurably weaker outcomes by fourth and fifth grade, a pattern that suggests a parent may want to look into with the school directly regarding the curriculum, instructional approaches, or support structures in the upper elementary grades.

When placed among the districts in St. Clair County, Delores Moye's overall proficiency index sits in the top quartile, indicating that the school's average performance across subjects and grades outperforms a substantial share of county schools. However, that county-level position masks the grade-by-grade softness visible in the school's own results.

O'Fallon itself is a growing community with a revitalized historic downtown district anchored by the Vine Street Market and walkable neighborhoods, though most residential development is highway-oriented suburban subdivisions. The broader area has anchors in civic recreation, the hospital system, and Scott Air Force Base. The housing market in the zip code is moderately priced, though the district itself has adopted successive large property-tax levy increases in recent years and in early 2024 approved a substantial working-cash bond without voter referendum, both facts that affect the true cost of homeownership for families in the district.

Staffing data, special-population enrollment counts, and free-or-reduced-price-lunch eligibility were not available in the school profile. The school serves only kindergarten through fifth grade, so state testing does not apply to those earlier grades.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
