Cyber Academy of South Carolina

Cyber Academy of South Carolina is a statewide, fully online public charter school headquartered in Greenville, SC, serving approximately 3,280 students in grades K-12 through the Charter Institute at Erskine.

For parents considering a virtual option, the most striking advantage is attendance. Only 6.6% of CASC students were chronically absent in 2024-2025, compared to 18.7% at nearby High Point Academy, 19.7% at Legacy Early College, and a staggering 47.8% at Washington Center—all well above the 22.3% state average. The school also shows strong momentum in keeping students on track: graduation rates climbed from 76.7% in 2020-2021 to 86.6% in 2024-2025, now matching the state average, while dropout rates fell by two-thirds to just 2.1%. This is accomplished with remarkable efficiency, spending only $9,808 per student—far less than the $12,892 to $47,151 spent by nearby brick-and-mortar schools.

However, the academic picture is more challenging. While CASC students perform near state averages on the English 2 exam (81.8% vs. 83.8% statewide), math proficiency lags dramatically. In 2025-2026, only 24.2% of 3rd graders, 15.4% of 4th graders, and 14.3% of 5th graders met state standards—gaps of 35-37 points below state averages. The pattern persists into high school, with Algebra 1 proficiency at 39.3% versus 64.6% statewide. This contrast between strong persistence metrics and weak math outcomes suggests the virtual format excels at keeping students engaged and enrolled, but translating that engagement into STEM learning remains the school's biggest hurdle. For families prioritizing flexibility and attendance, CASC is compelling; for those focused on math achievement, it warrants careful consideration.
