Mosaic Digital Academy K-12, Port St Lucie FL

Original Research by School Decision on Mosaic Digital Academy K-12

Mosaic Digital Academy K-12 is a public school in Port St. Lucie serving kindergarten through twelfth grade, operated within the St. Lucie County school district. Its enrollment is small relative to what you would typically expect from a K-12 school, and the student body is notably spread thin across all grade levels, with each grade cohort quite modest in size. The school is not a charter and carries no magnet designation. Program details were not available in the data, so the full picture of what the digital or blended-learning model looks like in practice is something a parent would want to explore directly with the school.

Demographically, the student body is roughly split between Hispanic and white students, each making up about a third of enrollment, with Black students comprising roughly a fifth and smaller shares of other backgrounds. About a quarter of students qualify for free or reduced-price lunch, which is on the lower side for St. Lucie County public schools. Data on students with IEPs or English learner designations was not reported, so families with those needs should ask the school directly about services.

State testing results from Florida's FAST assessments, reported for the 2024-25 school year, show a mixed picture across grade levels. In ELA, the school performs quite strongly in some middle grades, with sixth grade and seventh grade results standing out as high. Third grade ELA is also solid. Fourth and fifth grade ELA results are more moderate, and eighth grade falls in a similar range. Math tells a somewhat different story: third, sixth, and eighth grade results are strong, while fifth grade math is lower. Seventh grade math results were suppressed, likely due to the small size of that cohort. In science, fifth grade results are moderate and eighth grade comes in above the midpoint. These are recent single-year results with no prior trend data available to establish whether the school is improving, stable, or declining, so a parent may want to ask the school directly about how these numbers have moved over time.

A graduation rate was not reported, and civil rights outcomes data was not available. Given the school's name and apparent mission, a parent of a high schooler should ask specifically about graduation pathways, any dual enrollment or AP access, and how the digital format prepares seniors for college or career.

Because there is only one district in St. Lucie County for comparison purposes, the neighbor comparison set was too small to yield meaningful positioning on proficiency, chronic absenteeism, or graduation rate.

Port St. Lucie itself is one of the faster-growing cities in Florida, publicly reported as among the state's largest cities by population, with growth concentrated in western master-planned areas like Tradition and Southern Grove. The city was designed as a sprawling residential community with limited walkability outside a few planned pockets, so car dependence is the norm. The housing market near the school's zip code shows values that have dipped modestly year over year and now sit roughly in line with the Florida statewide median, while rents have also softened slightly. At current mortgage rates, monthly ownership costs are meaningful for a median-priced home, and rent consumes a substantial share of a typical household's income.

The St. Lucie district has been actively building to keep pace with growth, publicly reported to have opened a new high school in Tradition in August 2025 and planning a new K-8 for 2026. A voter-approved operating millage funds teacher pay, school resource officers, and mental health services, with renewal expected to go before voters again. A separate half-percent sales tax, also voter-approved, supports facilities and construction. These investments reflect a district under real growth pressure, which is context worth keeping in mind when thinking about resources and attention across schools.

Mosaic Digital Academy is likely a good fit for a family seeking a small, nontraditional learning environment with a degree of flexibility, and who can engage directly with the school on specifics around curriculum delivery, high school programming, and support services. The academic results at tested grade levels are generally encouraging, though the small cohort sizes mean results can shift substantially from year to year.

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.
