Original Research by School Decision on Mater Academy Biscayne North Miami Beach Middle School
Mater Academy Biscayne North Miami Beach Middle School is a public charter school serving sixth through eighth grade, located on NE 12th Avenue in Miami, Florida, and operating as part of the Miami-Dade charter landscape under the Miami-Dade district umbrella. Its address places it near the North Miami Beach area, in a dense urban setting that reflects the broader character of Miami: multilingual, majority-Hispanic, and shaped by the rhythms of a large coastal city.
The school is mid-sized for a middle school serving three grades. Its student body is predominantly Hispanic, with Black and white students each representing meaningful shares of enrollment. Just over half of students qualify for free or reduced-price lunch, meaning the school draws from a cross-section of working- and middle-class families. Data on English learner rates and students with IEPs were not available in the provided records, so parents of students in those populations may want to ask the school directly about supports.
On Florida's FAST assessments, the academic profile here is genuinely strong, particularly in math. Sixth graders tested at a level that puts nearly the entire cohort at proficiency, which is a standout result by any reasonable measure. Seventh and eighth graders in math also show proficiency well above what most middle schools post statewide. ELA results are solid in sixth grade, with a modest stepdown through seventh and eighth, where roughly three in four eighth graders reached proficiency. That pattern, reading proficiency trailing math by a consistent margin across grade levels, is worth a follow-up conversation with the school about how literacy is developed in the upper middle grades. Science is tested only at eighth grade in Florida's system; the result there is positive, with roughly two-thirds of students reaching proficiency, though it sits below the math performance. Trend data was not available, so whether these results represent improvement, stability, or a shift is unknown.
The enrollment data carries a curiosity worth noting: eighth grade shows no students enrolled, yet eighth-grade assessment results are reported. This likely reflects a timing gap between the roster snapshot and testing data, but a family enrolling an incoming sixth grader can reasonably expect the full three-grade structure to be present.
The housing market surrounding the school has seen a meaningful pullback in home values over the past year, with the local zip code dropping more than the statewide average, which itself has softened. Rents have edged down slightly as well, though they remain at a level where a substantial portion of income goes toward housing costs. By national affordability benchmarks, the Miami market is expensive relative to household income. Families considering this area should weigh that the current price softening may represent a buying window or simply reflect broader Miami-Dade demographic shifts: the county publicly reported losing residents in the most recent year, driven in part by an immigration slowdown, and Miami-Dade Public Schools has seen district-wide enrollment decline.
That enrollment decline has a direct practical consequence. As of spring 2026, the Miami-Dade district was weighing closing or consolidating up to nine schools, with some campuses being reconfigured into new grade structures including K-8 and 6-12 models. Families moving into the area should confirm this school's status and boundaries before assuming a stable assignment. Charter schools operate under their own charters and are somewhat insulated from district boundary changes, but it is worth verifying directly.
On the district finance side, Miami-Dade voters approved a property tax increase several years ago to fund teacher pay and school safety staffing; that higher rate is set to expire in 2027 unless voters renew it, which matters both for homeowners calculating costs and for anyone thinking about staffing stability in the years ahead.
A state cell phone policy affecting all Miami-Dade schools, including charters, is also in motion, with Florida moving toward a full school-day restriction. Families with strong feelings either way about phone access during school hours should monitor how that plays out, as the statewide policy is expected to be finalized by end of 2026.
Comparison proficiency data relative to other Miami-Dade county districts was not computed due to the small number of entities in the comparison set, so a wider benchmark context is not available here.
