Key Largo School, Key Largo FL - Test Scores & Data

Original Research by School Decision on Key Largo School

Key Largo School sits on the Overseas Highway at the northern end of the Florida Keys, serving children from pre-K through eighth grade as the sole public PK-8 campus in a community where civic life is strung along a single road corridor rather than gathered in any kind of town center. Families who move here understand that after eighth grade, students travel down-island to Coral Shores High School in the Tavernier and Islamorada area, making this school a complete pathway only through middle school.

The student body is sizable for a PK-8 school in an unincorporated coastal community. Hispanic students make up the largest share of enrollment, with white students the second-largest group; Black and multiracial students round out the remainder in smaller proportions. A substantial majority of students qualify for free or reduced-price lunch, which places this well above the midpoint for economic need among schools in communities of comparable size. Data on English learner rates and students with IEPs was not available in the materials provided, so a parent with questions about those support structures should ask the school directly.

On Florida's FAST assessments in the most recent school year, results are uneven and worth reading carefully by grade. Math performance is strong in third, sixth, and seventh grades, where most students are reaching proficiency, and more modest at the fourth, fifth, and eighth grade levels, where less than three in five students are meeting the standard. In ELA, fourth and seventh grades come in with solid majority proficiency; third, sixth, and eighth grades sit in the low-to-mid range; and fifth grade ELA is below half, which is the weakest single result in the data. On the statewide science assessment, results at both tested grade levels land below the midpoint. Fifth grade across both math and ELA shows a consistent dip worth noting; a parent may want to ask the school about what supports or instructional changes are being directed there. The data does not include trend information, so whether performance is improving or stable over time is not something that can be characterized here.

No multi-year trend data was available, and because Monroe County has only one school district, the comparison framework did not yield a meaningful relative ranking for this school. The academic picture comes from the state assessment results alone.

The housing market surrounding Key Largo School is among the most expensive in Florida, running far above the state and national benchmarks. Home values are well into the seven figures, with typical monthly ownership costs that far exceed what national income figures would support, and the rent burden is also high. The gap between ownership costs and rental costs is notable. Publicly reported recent development activity in Key Largo has concentrated on workforce-affordable rental housing near mile marker 95, aimed at households earning within reach of area median income, with several projects in various stages of planning and approval as of early 2026. That context matters for families considering whether this community is accessible: the private market is expensive, but targeted workforce housing is being added incrementally.

On the district side, Monroe County voters renewed two school funding referendums in late 2024, publicly reported to secure teacher salaries, school nurses, and a school resource officer at every campus, and to fund facility work. Those renewals extended an existing arrangement at no new tax cost. Separately, the district adopted a property tax rate increase for the 2025-26 fiscal year, directed toward capital needs including new construction, safety upgrades, and buses. Families buying property in the district would see that reflected in their tax bills.

The school has no reported magnet designation, and program offerings beyond the core curriculum were not available in the data provided. Key Largo itself, whatever its limitations as a car-dependent linear community, is immediately adjacent to John Pennekamp Coral Reef State Park and the Florida Keys National Marine Sanctuary, and the broader community's orientation toward marine science, diving, and the natural environment is a practical backdrop for a child growing up here, even if the school's formal programming around it is not documented in what was provided.

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.
