Original Research by School Decision on Lalumier Elem School
Lalumier Elementary School serves the early grades—prekindergarten through third grade—in Centreville, now part of the consolidated city of Cahokia Heights in St. Clair County, Illinois. The school enrolls a small population, with the bulk of students concentrated in the lower grades. The student body is predominantly Black, with a small number of Hispanic and multiracial students and a handful of white students.
The school sits in a low-income, flood-prone neighborhood that has experienced decades of disinvestment. Centreville was historically an independent city but merged with Cahokia and Alorton in 2021 to form Cahokia Heights. The area remains characterized by aging mid-20th-century housing, high poverty, and chronic stormwater flooding that affects daily life. The housing market in the zip code is affordable relative to the state and national benchmarks, with median listing prices well below those benchmarks, though the supply of listings has grown. The broader Metro East labor market offers work in health care, food service, retail, and skilled nursing, and the school district itself is a sizable employer.
State testing data available for third grade in the most recent year shows both reading and math proficiency well below the midpoint among districts in St. Clair County. Only a small share of third graders scored proficient or above in either subject. The school does not report free-or-reduced-price lunch counts or special education and English learner rates, so those details are not available. Because Lalumier serves only grades PK through 3, it does not administer state assessments in the upper elementary grades, which explains why data appears only for grade 3.
The parent district, Cahokia Unit School District 187, is undertaking a major long-term investment: a new high school is scheduled to open in fall 2026 on donated land, financed through lease certificates rather than a property tax increase. That capital project reflects the district's effort to modernize aging facilities across its system. For families considering this school, the key question is how early-grade instruction aligns with their child's needs and learning style, since the school is small and serves the youngest students before they move into the broader district in fourth grade and beyond. A parent may want to look into the school's instructional approach, class sizes, and support for early literacy and numeracy development, as the third-grade proficiency data signals an area of concern relative to county peers.
