Original Research by School Decision on Arlene Welch Elementary School
Arlene Welch Elementary School serves kindergarten through fifth grade and sits in Naperville, a large suburban city about 28 miles west of Chicago. The school draws from a diverse student population: roughly half the enrollment identifies as Asian, with the rest distributed among White, Black, Hispanic, and multiracial students. The school has no data on free-or-reduced-price lunch rates, so a reader cannot gauge economic need from that measure; data on special education and English learner enrollment were also not available.
The enrollment sits at a moderate size for its grade span, with roughly similar numbers per grade from kindergarten through fifth. The school is a regular public school within Indian Prairie CUSD 204, the district serving Naperville and surrounding areas.
On Illinois state testing, Arlene Welch's recent results show mixed academic terrain. In English Language Arts across third, fourth, and fifth grades, proficiency ranges from roughly three-in-five to just under seven-in-ten students meeting or exceeding state standards. Mathematics proficiency is lower: third grade sits at about two-in-three, fourth grade drops to about one-in-two, and fifth grade recovers slightly to roughly three-in-five. Science results appear only for fifth grade, at just under three-in-five proficiency. Data from the grade six and seven tests are missing, which reflects the fact that the school does not serve those grades. All tested students participated in the state assessment in the grades where it is offered. The results come from the Illinois Assessment of Readiness (IAR) for math and ELA; a note that Illinois changed proficiency cut scores for the 2024-25 year means comparison to prior years should be approached cautiously with the school directly.
Against a comparison group of districts in Will County, Arlene Welch's overall proficiency index—an average of the proficiency rates across tested subjects and grades—sits above the midpoint. This positions the school in the stronger half of that county cohort, though not at the very top.
The Naperville housing market where Arlene Welch draws enrollment is characterized by strong property values in the mid-range for the region and moderate rental costs. The neighborhood has a walkable downtown anchored by the Riverwalk, a roughly one-to-two-mile brick path along the DuPage River with recreation access and pedestrian connections to downtown Metra stations, schools, and shops. The area is on a slow growth trajectory, with steady residential development including new subdivisions and downtown infill projects. Major employers span healthcare, education, distribution, and consumer goods, anchored by Edward Hospital, the two main school districts, KeHE Distributors, and others. The Naperville Public Library and parks system are civic anchors.
At the district level, Indian Prairie CUSD 204 recently passed a bond referendum in November 2024 that will fund safety upgrades and infrastructure modernization across its schools over roughly two decades of repayment. The bond structure continues the existing tax rate rather than letting it decrease, a long-term commitment that affects family finances in the district. Additionally, the district has adopted a new CommonLit-based English Language Arts curriculum for middle schools—a change in pedagogy that does not directly affect this elementary school but signals the district's approach to instruction and the kind of curricular shifts families can expect as their children progress.
A parent considering Arlene Welch should view the school as one with solidly above-average proficiency in the county context, stronger performance in reading and language arts than in mathematics, and a diverse peer environment. The housing and community environment is stable and walkable in parts of Naperville, with good access to parks, recreation, and commuter transit. The district context reflects ongoing investment in facilities and curriculum modernization, with meaningful long-term financial commitments already in place.
