Original Research by School Decision on Lisle Elementary School
Lisle Elementary School serves a diverse student body in a stable DuPage County suburb with a mixed-use character. The school is a regular public elementary building housing roughly three-quarters of a small to mid-sized elementary enrollment, spread across pre-K through fifth grade, with each grade from kindergarten through fifth containing a cohort of around standard elementary size. Demographically, the enrollment reflects Lisle's suburban diversity: the student population is majority white, with meaningful shares of Hispanic, Black, and Asian students and a smaller population of students identifying with multiple races. No data on free-or-reduced-price lunch status, students with IEPs, or English learners was available, so a parent would want to contact the school directly to understand how much economic or academic need the building serves.
On state testing, the school shows a clear performance gradient by grade level and subject. In math, third and fourth graders are proficient at above-average rates within the county district comparison set, with mid-range to strong performance. Fifth grade math proficiency drops notably, suggesting a potential transition point or content shift that may warrant attention. In English language arts, the pattern is more consistent, with fourth and fifth grades performing above the county midpoint and third grade near it. Science proficiency in fifth grade (the only grade tested) sits slightly below the county median. Overall, the school's proficiency index across tested subjects and grades places it above the midpoint among the county's schools, a meaningful signal that the teaching and learning environment produces results in line with or better than many peers. Families should note that grade six data is missing because the school does not serve middle grades; Lisle Junior High serves grades six through eight.
The school occupies a position within a district in transition. Lisle CUSD 202 is in the midst of a multiphase renovation of its sole junior high school, where the school's students will go in sixth grade. That renovation work, which included summer 2024 activity and continued through summer 2025 with HVAC, health and safety, and security updates, is a lasting upgrade to the building families' children will eventually attend. The district is also operating under a three-year teacher contract approved in 2024 that sets salary growth through the 2026-27 school year and reflects ongoing reliance on local property taxes to fund nearly all district revenue, which shapes the district's budget environment going forward.
Lisle itself is a suburban village with both residential and corporate character. It sits west of Chicago in DuPage County and combines established tree-lined neighborhoods with a downtown core along Main Street near a Metra BNSF station, and a separate corporate corridor along I-88 housing major employers including Navistar and Molex. The village is in active infill redevelopment, with new townhouse and single-family developments approved or under construction aimed at adding housing closer to downtown. Housing values in the area reflect a middle-to-upper-suburban market, stable with modest year-over-year appreciation. The Metra station and downtown retail district anchor local civic life, while the Morton Arboretum to the north is a major regional recreational draw. Pace bus service connects to Naperville.
For a parent or resident evaluating this school, the elementary testing results suggest solid instruction in core subjects, particularly in the mid-elementary grades, with a dip in fifth grade math that may merit discussion with the school. The broader school environment and support structures are not detailed in available data, so questions about class size, arts and enrichment programming, special services, or school culture would be worth pursuing directly with the building.
