Original Research by School Decision on Michael Grimmer Middle School
MichaelGrimmer Middle School, a regular public school in Schererville serving grades five through eight, sits within the Lake Central School Corporation. The school draws students from a suburban Chicago town that grew rapidly for decades but has since settled into a period of slight population decline, with new commuter rail access opening in early 2026 improving regional transit connections.
Academically, Grimmer Middle School stands out within its county. On Indiana’s ILEARN assessments, the school’s overall proficiency index across tested subjects places it in the top quartile relative to districts in Lake County. That index – a composite of performance in math, English language arts, science, and social studies – reflects a level of achievement well above the median among county districts. In English language arts, a majority of students reached proficiency, while math proficiency, though lower, remained solid. Science and social studies results, tested only at certain grade levels, also showed a majority of students meeting the state’s proficiency bar. The school had full participation in the math and ELA tests, and the science and social studies participation rates were not reported, though the tested counts suggest broad coverage. Because this is a middle school, there is no graduation rate to consider, and data on chronic absenteeism was not available.
The student body numbers roughly several hundred, spread fairly evenly across grades five through eight. The demographic composition is predominantly white, with a substantial Hispanic presence, a smaller Black population, and modest shares of Asian and multiracial students. About a third of students qualify for free or reduced-price lunch, a marker of moderate economic diversity. Information on students with disabilities and English learners was not provided, so a parent may want to ask the school directly about those supports.
Schererville itself is a car-dependent suburb built around the intersection of major highways, with a small historic downtown along Old Lincoln Highway. Housing values in the area are above the Indiana state benchmark but nearly on par with the national median, and rents are moderate relative to incomes. The town’s growth has slowed markedly after a long boom, and the most notable recent infrastructure change is the opening of two Monon Corridor commuter rail stations nearby, offering a new transit option for commuters to Chicago. Within the Lake Central district, elementary school boundaries were recently updated, so families deciding where to buy or rent should check which elementary school a residence feeds into, as that pattern can influence the elementary experience before students reach Grimmer.
No data was available on course offerings, discipline rates, staffing ratios, or attendance patterns, leaving open questions about day-to-day school climate and access to advanced or support programs. The school does not operate as a charter or magnet, and its Title I status was not reported, so federal funding for low-income student supports is unclear.
For a family looking at middle schools in northwest Indiana, Michael Grimmer Middle School presents a picture of above-average academic performance within its county, set in a stable, car-oriented suburb with solid housing options and improving transit links. The student body is diverse in terms of race and economic background, though the school itself is of a typical size for a middle school. The missing pieces – special education and English learner data, discipline records, program details – are worth pursuing directly with the district to round out the picture.
