Original Research by School Decision on Mater Preparatory Academy Miller
Mater Preparatory Academy Miller was a charter school located on Sunset Drive in Miami, Florida, serving middle school grades. The school is now closed, as reflected in its official status, and is no longer accepting students or operating programs.
Because the school has closed, nearly all of the data fields that would normally inform a parent's decision are absent or inapplicable. Enrollment figures, demographic composition, academic performance results, state assessment data, staffing ratios, and civil-rights metrics are all missing from the record. There is no graduation rate to report, which is expected given the middle school grade band. The absence of academic data here is not a reflection of performance; it is simply a consequence of the school's closure and the limits of what was recorded.
For a family researching this specific school, the practical takeaway is straightforward: it is no longer an option.
The broader Miami-Dade context is worth understanding for anyone navigating school choice in the area. The district is publicly reported to be managing a sustained enrollment decline, with a wave of proposed school closures and consolidations across all three of its geographic regions as of spring 2026. Families moving into Miami-Dade should be aware that attendance boundaries and school configurations are in active flux, and a child's assigned school could change before or shortly after a move. The district has also been operating under a property-tax referendum approved by voters that funds teacher compensation and campus security; that levy is set to expire and would require renewal to continue.
Housing in the zip code where this school was located sits well above both the Florida state median and the national median in home values, and rents in the area consume a substantial share of typical household income. Miami overall is a large, dense urban city with strong walkability in many neighborhoods, a layered public transit system anchored by Metrorail and the free Metromover, and a heavily service-oriented economy anchored by government, health care, education institutions, and tourism. The city's population grew through much of the 2010s, though the broader county has seen a measurable decline more recently, driven in part by slower immigration.
For any parent who encountered this listing while searching for a school, state testing data was not available, program offerings were not available, and no comparison data against neighboring districts was present in the record. The only firm conclusion the data supports is that Mater Preparatory Academy Miller is closed and should be excluded from any current school search in Miami-Dade.
