Original Research by School Decision on O Neill Middle School
O Neill Middle School serves grades seven and eight in Downers Grove, a western Chicago suburb in DuPage County. The school sits in a diverse, densifying community marked by a walkable downtown anchored by the Main Street Metra station, established neighborhoods of older and rebuilt homes, and a mix of retail, healthcare, and light industrial employers. Housing values in the area are moderate to upper-middle range for the region, and the community has been adding multifamily housing downtown while single-family areas continue their notable pattern of teardown and rebuild.
The school's enrollment is small to mid-sized for its grade band, with roughly equal numbers of seventh and eighth graders. The student body is predominantly white, with meaningful representation of Hispanic students and smaller shares of Asian and Black students. Free-or-reduced-price lunch data and information on students with IEPs or English learners were not available.
On state testing, O Neill shows a clear subject and grade pattern. In English language arts, performance is strong: seventh graders proficient or above at roughly four-fifths, and eighth graders at roughly three-quarters. Science results for eighth grade are solid at roughly two-thirds proficient. Mathematics, however, is the softer subject area. Seventh-grade math hovers near three-fifths proficient, while eighth-grade math drops to roughly two-fifths proficient. Across all tested grades, participation rates are very high, exceeding ninety-nine percent. State assessment proficiency criteria shifted this year, making year-to-year comparisons unavailable from the data provided.
Within DuPage County's school districts, O Neill's overall proficiency index—an average across all tested subjects and grades—places it above the midpoint. That positions it in the middle to upper-middle band regionally, though the mathematics results, particularly in eighth grade, suggest a parent may want to look into what support or curriculum strategies the school has in place for students in that subject.
The school is part of Downers Grove Grade School District 58, which is undergoing substantial change. A community-approved facilities bond approved in November 2022 is funding renovation and expansion of all thirteen district buildings through summer 2026, including new secure entry vestibules, HVAC upgrades, and notably, expansions to both middle schools. The bond raised the district property tax rate, a cost that families weigh when considering the area. Beginning the 2026-27 school year, the district shifts from a K-5 / 6-8 model to a PK-5 and 6-8 model, moving sixth graders into the middle schools. This will affect where younger siblings attend school and is intended to ease overcrowding at the elementary level. Since O Neill has been expanding in preparation, this transition will reshape the composition and capacity of the school.
O Neill does not sit in the downtown core but rather on a neighborhood campus in a residential area. The school serves a community with easy access to the Metra station for commuters and a downtown with independent shops, restaurants, and community events, though civic and family life tends to center in neighborhoods rather than in a single downtown hub. Major local employers include healthcare providers, Dover Corporation, Pepperidge Farm, and the school district itself. For families considering Downers Grove, the ongoing physical modernization of schools and the upcoming grade reconfiguration are central considerations alongside the area's housing costs and its combination of suburban and urban-oriented amenities.
