Original Research by School Decision on Macomb Montessori Academy
Macomb Montessori Academy is a public charter school in Warren, Michigan, serving students from pre-kindergarten through eighth grade. It sits on East Nine Mile Road in the 48089 zip code, on the southern edge of Warren near the Detroit border. The school is authorized by Lake Superior State University and managed by Choice Schools, with a charter that was publicly reported as renewed in 2023 and secured through 2028. For families considering enrollment, that renewal provides a window of stability for a school of this size and type.
The school is small for its grade band, with an enrollment concentrated heavily in the early grades. Kindergarten and first grade hold the largest shares of students, while upper grades taper off and seventh and eighth grade currently show no enrolled students. Pre-kindergarten also shows no enrollment, despite the grade span including it. This suggests the school's center of gravity is early elementary, and a family with older children may want to ask how the upper-grade experience is structured and whether those grades are being built out.
The student body is nearly entirely Black, and a very large share of students qualify for free or reduced-price lunch. The school does not report IEP or English learner figures, so those pictures are incomplete from the available data. No Title I status was provided either.
On Michigan's M-STEP assessments for the most recent school year, proficiency rates across math, English language arts, science, and social studies are low. In math, third grade showed a small share of students reaching proficiency, while fourth, fifth, and sixth grades had no students scoring proficient. English language arts followed a similar pattern, with sixth grade showing a modest portion proficient and the lower grades showing none. Science and social studies results for fifth grade also showed no proficient students. Tested groups in each grade are small, which means a few students moving in or out of proficiency can shift the picture considerably. Against districts in Macomb County, the school's overall proficiency sits in the bottom quartile. These results are a fact a parent will want to discuss with the school directly, particularly how the Montessori approach to learning maps onto state assessment expectations and what interventions or supports are in place.
No multi-year trend data was available, so it is not possible to say from the provided information whether these results represent a new pattern or a longer-standing one. Participation rate data was also missing from the state results. Because the school does not serve high school grades, no graduation rate applies, and that gap reflects the grade band rather than a missing metric.
Warren itself is a large, auto-oriented inner-ring suburb of Detroit and the largest city in Macomb County. Publicly reported sources describe it as sprawling across wide arterial roads with no traditional walkable downtown. The city's economy is anchored by General Motors, the U.S. Army Detroit Arsenal, and Stellantis, making it one of the most industrially focused suburbs in metro Detroit. Warren experienced rapid growth through the mid-twentieth century and has been gradually declining in population since, with an aging housing stock and no major new housing boom. The 48089 zip code, where the school sits, has home values well below both the state and national benchmarks, and rents are modest relative to broader metro-area pricing. A family buying or renting near the school would find relatively affordable housing in a mature suburban setting.
The available data did not include information on course access, staffing ratios, discipline, attendance, chronic absenteeism, or specific program offerings beyond the Montessori framework. Without those pieces, a fuller picture of the school's day-to-day environment and support structures is not possible from the data alone. A parent weighing this school would benefit from asking directly about staff continuity, classroom composition across the mixed-age Montessori model, and how the school is working to lift proficiency results given where its students currently stand.
