Original Research by School Decision on Somerset Island Prep
Somerset Island Prep is a small charter high school sitting on Flagler Avenue in Key West, Florida, serving students in grades nine through twelve. Its enrollment is quite small, even by the standards of a charter school serving a single high school grade band, and that intimate scale shapes nearly everything about the experience a student would have there.
The student body reflects the demographics of the Florida Keys broadly. White students make up a majority, Hispanic students a substantial share, and Black students a smaller portion. Multiracial students round out the count, with no reported Asian or Pacific Islander enrollment. A minority of students qualify for free or reduced-price lunch, a lower economic-need rate than many public high schools in Florida, though this figure is simply what the enrollment data shows rather than a signal about selectivity or access.
State assessment data was not available for Somerset Island Prep. That gap is worth naming plainly: without proficiency results or multi-year trend data, it is not possible to characterize academic outcomes from tested performance. A parent who wants a picture of how students here are performing relative to state standards would need to ask the school directly. Graduation rate data was similarly not reported. Chronic absenteeism data was also absent. For all three of those metrics, the comparison with other districts in Monroe County could not be made because the school-level figures were not present, not because the school performed poorly.
Program information was not included in the data provided, so what Somerset Island Prep offers in terms of AP courses, dual enrollment, career pathways, or extracurriculars is a genuine gap in this account. Given the very small enrollment, a prospective family should ask the school directly how broad its course catalog is and whether students can access programs at Monroe County School District campuses or through community college partnerships.
The school sits in a city that operates more like a small island community than a typical Florida municipality. Key West is the southernmost city in the continental United States, and publicly reported sources describe it as highly walkable and bikeable, particularly around its commercial center. A free bus loop circulates through major destinations on the island daily, and the city's transit department runs several routes plus a shuttle connecting Key West to Marathon. The Monroe County May Hill Russell Library, described publicly as one of the oldest libraries in Florida, anchors civic life for residents and draws visitors from across the Keys.
The housing market surrounding this school is extreme by any measure. Home values in the relevant zip code run dramatically higher than the statewide median and the national median, and they have softened slightly in the past year. Rents are also well above national norms, having ticked upward recently. The rent-to-income ratio and the estimated monthly mortgage payment both reflect a market where affordability is a real constraint for working families. Monroe County's property owners also face a direct cost change: the school district adopted a millage increase for the 2025-26 fiscal year, directing new capital revenue toward construction, safety upgrades, ADA compliance, and buses. Separately, in November 2024, voters renewed two longstanding school funding referendums that support teacher salaries and place a nurse and school resource officer at every school. District leaders had warned ahead of that vote that failure would have meant significant staffing cuts, so the renewals provide some near-term stability for district-operated schools.
For a family already living in Key West or planning a move there, Somerset Island Prep's small size may appeal to students who want a close-knit environment and less anonymity than a larger campus would offer. The missing performance data means the academic picture here is genuinely incomplete, and a parent weighing this school against other options in Monroe County should treat a direct conversation with school leadership as a necessary step rather than an optional one.
