Supplemental Instruction
SI is an internationally recognized approach to learning that combines “what to learn” with “how to learn.” Students in SI-supported courses attend one of three weekly group review sessions guided by trained peer leaders. SI support is proven to increase grades and retention in the course.
The College of Charleston's SI program is proudly accredited through the International Center for Supplemental Instruction
