Charter Institute at Erskine

The Charter Institute at Erskine is a network of 26 public charter schools across South Carolina, serving roughly 23,000 students in elementary, middle, and high school grades, with a mix of traditional brick-and-mortar campuses and large virtual academies. Overall, the district ranks near the middle of the state (47th percentile), but that average hides a dramatic split between a handful of elite schools and several that are struggling significantly.

For parents, the standout options are clear. Brashier Middle College Charter High and Gray Collegiate Academy both achieve 100% graduation rates, near-perfect test scores, and very low chronic absenteeism, ranking in the top 5% of all high schools in the state. Langston Charter Middle is the top middle school in the network, with 80-90% proficiency in math and ELA. At the elementary level, Belton Preparatory Academy is a strong choice, jumping to the 94th percentile statewide. On the other end, Heron Virtual Academy of South Carolina has a 49.7% graduation rate and 51.1% chronic absenteeism, while Willie Jeffries School of Excellence and Clear Dot Charter School show single-digit proficiency in core subjects.

The virtual schools, which enroll over half the district's students, present a mixed picture. School Connections Academy, Cyber Academy of South Carolina, and South Carolina Virtual Charter School all have graduation rates near or above the state average and remarkably low absenteeism, but they consistently struggle with math, where proficiency often falls below 30%. Notably, higher spending per student does not guarantee better results—Calhoun Falls Charter School spends the most ($17,366 per student) yet ranks in the bottom 13th percentile, while Gray Collegiate Academy spends far less and achieves top-tier outcomes. The "middle college" model, where high schoolers learn on a college campus, appears to be the most effective approach in the network, while math instruction remains the biggest challenge across nearly every school.
