Original Research by School Decision on Mariposa Elementary School
Mariposa Elementary sits on SE Mariposa Avenue in the southeastern part of Port St. Lucie, serving children from pre-kindergarten through fifth grade. It is a regular public school within St. Lucie County's district, with an enrollment that places it on the larger end for an elementary school of its grade span.
The student body is racially and ethnically diverse. Hispanic students make up the largest share, followed by white students, then Black students, with smaller Asian and multiracial populations. A substantial majority of students qualify for free or reduced-price lunch, which reflects the socioeconomic profile of the surrounding neighborhood. Data on English learner enrollment and students with IEPs were not available in the data provided, so families with those specific questions would want to ask the school directly.
On Florida's FAST assessments for the most recent school year, the academic picture is uneven and worth examining closely. In math, third-grade proficiency is relatively strong compared with what the other grades show, and fourth grade sits not far behind. Fifth-grade math, though, drops sharply, well below the first two tested grades. ELA follows a consistent but lower pattern across all three grades, with third grade performing best and fifth grade lowest. The fifth-grade science assessment, the only science result available, lands in a similar range to the weaker ELA and math numbers. The data does not include prior-year results, so trend direction is unknown. Parents considering the upper elementary years in particular may want to ask the school what supports are in place to address the gap that appears in fifth grade.
No multi-year trend data was provided, and no comparison against other schools in St. Lucie County was possible from this data set because Mariposa is the sole school entity in the comparison universe supplied. A broader picture would require looking directly at district and state-level comparisons.
The school is part of St. Lucie Public Schools, a district that has been managing rapid enrollment growth. Publicly reported information indicates the district opened its first new high school in nearly a generation in August 2025 and is building a new K-8 school expected to open in 2026. Voters recently renewed both an operating property tax and a capital-outlay sales tax, the first funding teacher pay and school resource officers on every campus along with mental-health services, the second supporting new construction and safety upgrades. Families enrolling in Mariposa should confirm their attendance-zone assignment, since the district has been updating zone boundaries as new schools come online.
Port St. Lucie itself is a large, fast-growing city that was designed originally as a sprawling residential community with little commercial infrastructure at its core. Day-to-day life around Mariposa's southeastern address is car-dependent; walkability in most of the city is limited, and the school sits away from the planned commercial districts like Tradition in the west. Parks, canals, and the North Fork of the St. Lucie River are woven through the residential areas. The county operates a fare-free transit system, though service is primarily a weekday resource.
Housing near the school, based on zip-code-level data, is priced modestly below the Florida state median and close to the national median, with values down slightly year over year. Rents have ticked up marginally over the same period. The estimated monthly cost of ownership, including a standard mortgage at current rates, runs somewhat above local rent levels, so the rent-versus-buy calculus is tighter than in some Florida markets but not extreme. For families relocating to the area, the southeastern Port St. Lucie corridor offers more attainable prices than the newer master-planned communities to the west, though it also lacks some of the amenities concentrated in those newer districts.
Graduation rate and chronic absenteeism data are not applicable here, as Mariposa serves only pre-K through fifth grade. Program-level details such as enrichment, gifted services, or after-school offerings were not available in the data provided, so those are worth asking the school about directly.
