Carolus Online Academy

Carolus Online Academy is a large, alternative public charter school in Columbia, SC, serving 1,786 students in grades K-12 through a fully virtual learning environment, and it is part of the School Public Charter School District.

For parents considering this online option, the most pressing concern is student engagement and completion. The school's graduation rate is just 52.4%, compared to the state average of 86.7%, and its dropout rate of 12.2% is nearly six times the state rate. Chronic absenteeism affects 48.5% of students—more than double the state average—which is especially telling for an online school where attendance requires self-direction. This stands in stark contrast to other virtual schools in the area, such as School Connections Academy (0.4% chronic absenteeism) and South Carolina Virtual Charter School (1.2%), suggesting the challenges at Carolus are not inherent to online learning but rather to the school's specific support systems. Academic proficiency is also consistently low; for example, 8th-grade math proficiency was just 1.3% in 2024-2025, versus the state's 32.4%. One bright spot is English 2, where 77.17% of students were proficient—a significant jump from 21.15% in English 1—though still below the state average.

The school operates with a high student-teacher ratio of 27.9:1, higher than nearby virtual peers, and spends $9,912 per student, less than schools like American Leadership Academy South Carolina-Lexington Campu ($11,553) and Clear Dot Charter School ($12,810). While Clear Dot Charter School shares similar academic struggles, its chronic absenteeism (22.6%) and dropout rates (2.5%) are far better, highlighting that engagement and retention are particularly acute issues at Carolus. Parents should weigh these metrics carefully when considering whether this school can provide the structure and support their child needs to succeed.
