Original Research by School Decision on Spring Brook Elementary School
Spring Brook Elementary is a well-performing school in the Indian Prairie District, serving about half a thousand students in a primarily residential area of Naperville. The school sits in a thriving suburb with strong family demographics and steady growth; it feeds into a district undergoing significant modernization under a recently approved bond referendum.
In math, the school shows solid performance across the tested grades. Third graders approach proficiency rates in the upper range, while fourth graders are close behind. Fifth grade shows a visible dip, with a smaller majority of students meeting the proficiency bar. This grade-by-grade variation is worth watching if you have a child approaching fifth grade, though the school's overall proficiency index places it in the top quartile among Will County elementary schools, suggesting the performance is still strong relative to peers. English language arts tracks somewhat lower than math overall, with third and fourth graders in the upper-middle range and fifth graders near the three-quarter mark. Science, tested only in fifth grade, shows proficiency rates comparable to ELA at that level.
The school enrolls a diverse student body. Roughly one-third of students are Asian, about half are white, and smaller shares identify as Hispanic or multiracial. Enrollment has held steady at a moderate size for the grade band, with fifth grade representing the largest cohort. Data on free-or-reduced-price lunch eligibility and special education or English learner populations were not available, so a parent may want to ask the school directly about socioeconomic diversity and support services.
Naperville itself is a large suburban city west of Chicago with a reputation for strong civic life centered on the Riverwalk downtown, excellent parks, and a highly ranked public library. Families tend to be affluent and education-focused; median household income is above the national benchmark, and median home values reflect a solid suburban market with modest recent appreciation. Housing costs are fairly high, though the rental market is broader. The city has active new development, including infill downtown and emerging subdivisions on the south side.
The Indian Prairie District, which operates Spring Brook, is in the midst of substantial change. In November 2024, voters approved a major bond referendum that will fund safety upgrades, infrastructure work, and learning space improvements across the district over the next several years. The tax rate is expected to hold steady even as these bonds are issued, which matters for families weighing a move into the district. Additionally, the district recently adopted a new CommonLit-based English language arts curriculum for middle schools, shifting toward more writing and critical thinking. These are the kinds of district-wide initiatives that affect the school environment and trajectory for families staying in the system through high school.
Spring Brook's test results are accessible and solid, placing it above the county median on an overall proficiency index. The school sits in one of Illinois's most established suburban districts, with active civic participation and ongoing investment in facilities. For families prioritizing a well-resourced suburban setting with strong peer demographics and consistent academic performance in the primary grades, this school offers that profile. Parents of fifth graders, or those concerned about the visible softening in that grade, should feel comfortable asking the school about supports and instruction in math and literacy at that level.
