Grande Park Elementary is a regular public elementary school serving kindergarten through fifth grade in Plainfield, Illinois, within Community Unit School District 308. The school enrolls roughly two hundred students per grade band across a standard six-grade span, with a demographically mixed student body: just over half white students, with substantial Asian, Black, and Hispanic representation each in the range of around one-eighth of enrollment. The school sits in the Grande Park development area on the western edge of Plainfield's rapid suburban expansion, consistent with the village's positioning as one of the fastest-growing communities in Illinois.
On the most recent state assessments in English language arts and math, Grande Park's proficiency results show a pattern of moderate performance with grade-level variation. In third grade, the school reached around two-thirds proficiency in math and just under three-fifths in ELA. By fourth grade, ELA proficiency rose to nearly seven-tenths, a strength, while math proficiency dropped to roughly half, reflecting a common pattern of fourth-grade math difficulty. Fifth-grade results show math proficiency near that of fourth grade and ELA proficiency staying around three-fifths. In science, fifth-grade proficiency reached just above one-half. Participation in assessments was consistently strong across the school, with near-universal test-taking rates. A parent may want to look into what supports the school is putting in place for fourth- and fifth-grade math, where proficiency sits below the school's own ELA performance and below the school's third-grade math showing.
When compared to the other districts serving Kendall County, Grande Park's overall proficiency index places it above the median among its county neighbors, positioning it in the middle-to-upper range of district performance in the region. This context matters for parents evaluating whether the school's absolute numbers represent strength or concern within the local landscape.
The school serves a community experiencing substantial residential growth. Plainfield's housing market has appreciated over the recent period, with median home values in the area reflecting suburban proximity to Chicago. Mortgage affordability and rents are material considerations for families entering the market. The district itself is at an inflection point: in late 2024 the school board approved a long-range facility plan, and in 2025 the district began deliberations on a proposed bond referendum for the November 2026 ballot to address HVAC, roofing, and flooring needs at schools built during the early-2000s growth wave. Because the district is simultaneously retiring existing debt, officials project that property tax increases for debt service would be offset by decreases in the current debt-service burden, making this a topic worth reviewing if you are considering a home purchase in the district. The district has also made recent curriculum changes: in 2022 it replaced its K-5 social studies and junior high math curricula with project-based and problem-based inquiry materials available in English and Spanish, a shift that shapes daily classroom instruction for elementary students and families.
Data on free-or-reduced-price lunch eligibility, special education enrollment, and English learner counts were not available, so a complete picture of the school's student support landscape cannot be drawn from the materials provided. The school's website or direct communication with the school office would fill those gaps. Grande Park is a standard public elementary school without magnet or charter designation, serving its local attendance area within a district actively managing growth and aging infrastructure.
