Original Research by School Decision on Mater Preparatory Miller High School
Mater Preparatory Miller High School was a charter school located on Sunset Drive in Miami, and the records show it is now closed. Because the school is no longer operating, this narrative is offered as background for anyone researching it, rather than as a guide for enrollment decisions.
The school served only a middle grade band, and because of that grade range, state assessment data and graduation rate figures would not be expected in the way they apply to high schools. No academic performance data, enrollment figures, demographic breakdowns, or program information were available in the records, so those dimensions of the school's character cannot be described here.
The surrounding Miami context is worth understanding for any family weighing options in the area. Miami is a large, dense urban city with strongly differentiated neighborhoods. The stretch of Sunset Drive where this school sat falls within the South Miami area, near Coral Way's tree-lined blocks of Mediterranean Revival homes and closer still to the commercial and residential mix that characterizes that part of Miami-Dade. Publicly reported data shows the city's overall walkability is high, with downtown and inner neighborhoods among the most walkable in South Florida, a Metrorail line running through South Miami, and a free elevated people mover connecting downtown districts. Major employers in the area span county government, education, health care, and tourism, with the University of Miami, Baptist Health South Florida, and Jackson Health System among the large private anchors.
Housing in the zip code where the school was located carries prices well above Florida and national medians, with rents also running substantially higher than both benchmarks. Year-over-year, both home values and rents in this area have continued to edge upward, which matters for families evaluating what it costs to live near schools in this part of Miami-Dade.
At the district level, Miami-Dade County Public Schools is navigating real pressure from sustained enrollment decline, publicly reported to have produced proposed closures or consolidations affecting schools across all three district regions as of spring 2026. Families new to the area should be aware that school assignments can shift as boundary and grade-structure changes work through the system. A voter-approved property tax increase, set to expire in 2027 unless renewed, continues to fund teacher compensation and campus security, representing an ongoing cost for homeowners. The district has also been navigating state-level changes to cellphone policy, with Florida legislation advancing toward a required districtwide policy by the end of 2026.
Because this school is closed, families seeking a charter middle school option in Miami would need to look elsewhere within the Miami-Dade charter landscape.
