Summary:
Zip code 29574 in Mullins, South Carolina, is served by a single high school, Mullins High, which enrolls 557 students in grades 9-12 within the Marion 10 school district.
Mullins High is the only option for families in this area, so its performance defines the local educational experience. The school shows a mixed picture. On the positive side, its graduation rate of 88.4% beats both the district (87.1%) and state (86.7%) averages, and its English 2 proficiency (79.72%) is strong, outpacing the district by nearly 9 points. Algebra 1 proficiency (65.09%) is also right in line with state averages. However, the school faces serious challenges. Most concerning is the dramatic academic decline from the 2024-25 to 2025-26 school year: English 1 proficiency plummeted from 62.16% to 39.33%, and U.S. History fell from 61.06% to 41.31%. This caused the school's state ranking to drop from the 51st percentile to the 29th percentile in a single year. Chronic absenteeism is a critical issue, with 42.4% of students missing significant school time—nearly double the state average of 22.3% and well above the district's already-high 31.1%.
Despite spending a substantial $16,688 per student, the school's results in most subjects fall below state benchmarks, suggesting that funding alone isn't addressing the root causes of underperformance. The ranking history is volatile, showing a remarkable recovery from the 6th percentile in 2023-24 to the 51st percentile in 2024-25, only to collapse again—pointing to possible instability in leadership or teaching staff. While Mullins High is a relative bright spot within the Marion 10 district (which ranks 74th out of 75 districts statewide), the combination of extreme absenteeism, steep test score drops, and inconsistent performance makes it a school in urgent need of targeted interventions in attendance and literacy support.
