Summary

Charleston Charter School for Math and Science is a public charter school in Charleston, SC, serving 573 students in grades 6 through 12 within the Charleston 01 school district.

This school stands out for its remarkable graduation and dropout rates. With a 98.6% graduation rate and a 0.0% dropout rate for five consecutive years, it dramatically outperforms nearby traditional public high schools like North Charleston High (79.1% graduation) and Burke High (78.6% graduation). The school's mission shines through in its Algebra 1 results, where 96.96% of students score proficient, a 32-point advantage over the state average. English 2 scores are also strong at 91.2% proficiency. The school serves a diverse student body effectively, with strong statewide rankings for African American, White, and low-income students alike.

However, there are some areas to consider. While high school end-of-course exams are stellar, middle school SC READY scores in 6th-grade ELA (51.9%) and math (36.7%) lag behind district averages. The school's Gifted and Talented students ranked only in the 48th percentile in 2025-2026, suggesting the highest-achieving students may not be sufficiently challenged. Chronic absenteeism has also risen to 21.5%, though it hasn't impacted graduation rates. Compared to elite magnets like Academic Magnet High and Charleston School of the Arts, CCSMS doesn't match their raw test scores, but it offers a strong, mission-driven alternative that clearly outperforms most traditional public options in the area. At $20,489 per student, spending is higher than some peers but far more efficient than schools like Military Magnet Academy, which spends nearly double with far worse outcomes.
