Treasure Village Montessori Charter School, Islamorada FL

Original Research by School Decision on Treasure Village Montessori Charter School

Treasure Village Montessori Charter School sits on the Overseas Highway in Islamorada, a linear village strung across several islands in the Florida Keys. The school serves children from pre-kindergarten through eighth grade, making it the complete K-8 pathway for families who choose it. As a charter school operating within the Monroe County district, it is publicly funded and open without tuition, though enrollment is limited and the Montessori model is a deliberate pedagogical commitment, not simply a geographic default.

The academic picture from state FAST assessments is genuinely strong, particularly in the middle grades. Math proficiency climbs sharply as students move through the upper elementary and middle years, reaching very high rates in sixth, seventh, and eighth grades. ELA follows a similar arc: proficiency in third grade is solid, dips somewhat in the middle elementary years, then recovers to strong levels by seventh grade. Science results are split: the fifth-grade cohort sits at a modest rate, while eighth-grade science proficiency is among the highest reported across any tested grade here. That pattern, where the school's older students post notably stronger results than its younger ones, may reflect the cumulative effect of the Montessori approach, a cohort effect, or simply small group sizes at each grade level. With enrollment as small as it is, a handful of students can shift any grade's result considerably, so a parent would do well to ask the school directly about how it monitors and supports students who are not yet meeting proficiency. Trend data was not available in the state's reporting, so whether these results represent improvement, stability, or a shift from prior years is not something that can be characterized here.

The student body is small enough that every grade is genuinely intimate. The school draws mostly white and Hispanic students, with a relatively modest share qualifying for free or reduced-price lunch, suggesting the school's population skews toward families with more economic stability than is typical in many Florida schools. Data on English learners and students with IEPs was not reported, so families whose children have those specific needs should ask the school directly about services and capacity.

The community surrounding the school is unlike most Florida school locations. Islamorada is a car-dependent place organized entirely around US 1, with no walkable center, limited public transit, and an economy built on fishing tourism and hospitality. Housing costs here are among the most striking characteristics of this setting: home values in the area are dramatically higher than the Florida statewide median and well above national benchmarks, and rents run at a level that consumes a large share of typical household income. The gap between what local service and hospitality jobs pay and what it costs to live on the islands is the central tension the village is actively trying to address through workforce housing efforts. Families considering a move here for this school should weigh that context carefully. The village has worked to build some affordable rental units and has ongoing planning conversations about housing, but buildable land is scarce and state growth controls limit new development.

Founders Park on Plantation Key is the civic heart of the islands, with athletic fields, a pool, courts, dockage, and the community center all in one place. The Florida Keys Overseas Heritage Trail connects some residential areas by bike, though a car remains essential for most daily needs.

At the district level, Monroe County voters renewed two school funding referendums in late 2024, sustaining local dollars that support teacher compensation, school nurses, and school resource officers at every school. The district also adopted a property tax increase for the current fiscal year to fund capital projects including new construction, safety improvements, and equipment. Both developments are relevant to families buying homes here, since the first preserves existing staffing and the second adds to property tax costs.

No information was available on program offerings, course access, discipline data, or staffing ratios for this school, so those remain gaps a prospective family would need to fill by contacting the school.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
