Our combination of rigorous academics, student-centered learning, leadership, service, and internships challenges CCS students to grow as individuals.

Originally founded in 1970 as Sea Island Academy, Charleston Collegiate School (CCS) is an independent college preparatory school nestled within 50 acres on Johns Island, South Carolina.

Charleston Collegiate School provides an environment grounded in mutual respect to allow our school community to gain an appreciation and awareness of our differences. Our diversity creates an environment that fosters an appreciation of the values, skills and abilities of everyone.

CCS’s mission is to empower students in a project-based approach that values collaboration, innovation, and individuality to become resilient leaders for 21st century careers. To fulfill this mission we strive to develop students who demonstrate critical thinking and curiosity with our rigorous curriculum which is based on CCS’s Pillars of Education.


Project-Based Learning provides CCS students with the opportunity to uncover creative solutions to everyday obstacles with in-depth research and hands on application. Collaborative project skills prepare students for future professional application. CCS is deeply committed to the PBL educational model.

Financial Literacy & Entrepreneurship courses are an incubator for collaboration, brainstorming, and business planning. Our students are introduced to financial concepts early on so they have ample time to develop and nurture their entrepreneurial spirit as they grow. From this curriculum, CCS students learn how to start a business from idea to execution.

Leadership through Outdoor Education provides students with participatory opportunities to learn risk management concepts, effective communication skills, and group leadership in an outdoor setting. CCS’s 30 acre campus is equipped with an Outdoor Leadership Education Center (OEC). Our OEC is certified by the Association of Challenge Course Technologies (ACCT) and includes nature trails, kayak programs, tidal swamp and dock, plus a low ropes course with team building elements that are unique to our campus and curriculum.

The rigor of CCS’s curriculum reflects a deliberate transition away from Advanced Placement and Dual Credit coursework to an Advanced Learning model of College Prep and Honors classes, which are equivalent to International Baccalaureate Standard Level (SL) and Higher Level (HL) courses, respectively.
