The top reported proficiency rate is 42% in English language arts. The lowest is 30% in Science.
Original Research by School Decision on Horizon Elementary - 09
Horizon Elementary sits on the south side of Sioux Falls, in the Harrisburg School District, serving pre-kindergarten through fifth grade. It is a neighborhood elementary school in a district that has become the fastest-growing in South Dakota, managing steady enrollment increases and new construction to keep pace. That growth context matters for families here: the district is actively building and expanding, which can mean fresh facilities but also shifting boundaries and pressure on capacity.
On state assessments, Horizon's results tell a mixed story. English language arts is the relative bright spot, with a share of students testing proficient that sits above the school's math and science results. Math proficiency is lower, and science, which is tested only in a subset of grades, falls below that again. Participation is strong across all three subjects, so the results reflect nearly the full student body rather than a skewed subset. These are not standout numbers, and a parent weighing this school may want to look into how the building supports students who are below proficiency and what interventions or Tier II supports are in place. The state did not report average scale scores, so there is no finer-grained view of where students cluster within or below the proficient range.
The student body is predominantly white, with smaller groups of Hispanic, Black, multiracial, Native American, and Asian students. A modest share of students qualify for free or reduced-price meals, lower than what many urban elementary schools see, which generally reflects the relatively affluent south-side neighborhoods feeding into the building. The school did not report English learner or special education enrollment figures, so we cannot characterize those populations here. Class sizes across the grades are fairly even, with the largest cohort in kindergarten and the smallest in pre-kindergarten.
Horizon is part of the Harrisburg district rather than the Sioux Falls district, even though its address is in Sioux Falls. That distinction matters because Harrisburg has its own governance, feeder pattern, and growth trajectory. Publicly reported district information describes Harrisburg as the fastest-growing district in the state, with the city of Harrisburg itself expanding from a small town to a much larger community over the past two decades. The district has responded with new school construction and facility planning. For a family at Horizon, that means the elementary experience is embedded in a system under active expansion, and the middle and high school pathway a child would follow is part of that same growth story.
The surrounding community is Sioux Falls, South Dakota's largest city, publicly described as having shifted from an industrial base toward health care, finance, and retail. Sanford Health and Avera Health are the largest employers, and the absence of a state corporate income tax has drawn financial firms. Downtown offers a SculptureWalk, First Fridays, a river festival, and a paved loop trail for biking and walking. Falls Park, centered on the Big Sioux River cascades, anchors civic life. Outside the downtown core the city is largely car-dependent, with a bus network running weekdays and Saturdays. Horizon itself sits in a residential area well south of downtown, so daily life for families here is more suburban than urban.
The housing market in the school's zip code runs above the state benchmark, with home values and rents both higher than the South Dakota average. Monthly mortgage costs exceed typical rent by a meaningful margin, which affects the buy-versus-rent calculus for families moving into the attendance area. Rents have risen faster year over year than home values, a pattern worth watching for renters budgeting around the area.
Because Horizon serves only the elementary band, there is no graduation rate, no AP or dual-credit data, and no high school course access to assess. Those metrics will come into play later in the Harrisburg feeder chain. What a family can evaluate now is the quality of the early grades, the peer environment, and the growth context of the district their child would move through. The academic results at Horizon suggest a school doing steady but not exceptional work in the elementary years, in a community with strong amenities and a district investing heavily in its future.
