Supplemental Instruction (SI) is an academic assistance program that provides peer-facilitated weekly group study sessions to improve student retention and success in difficult courses. SI is available for all students in the targeted course who want to improve their understanding of course material and improve their grades.

SI sessions are regularly-scheduled, informal review sessions in which students compare notes, discuss important concepts, develop strategies for studying the subject, and predict test items. Students learn how to integrate course content and study skills while working together. The sessions are facilitated by SI tutors who attend class lectures, take notes, and act as model students.

The Supplemental Instruction program (SI) strives to positively impact academic achievement and student retention by creating and maintaining dynamic, interactive learning for individuals of all cultures, abilities, backgrounds and identities.
