Supplemental Instruction (SI)

What is supplemental instruction?

Supplemental Instruction (SI) is a program in which trained tutors are embedded in face-to-face courses that have been historically difficult for students. As embedded tutors, they work closely with faculty members to offer weekly review sessions and test prep outside of the class. All SI leaders (the embedded tutors) are specially trained and have previously taken the course and earned a B+ or better. Many of our SI leaders have been recommended by faculty themselves. SI Leaders attend all class sessions to keep up with course material and create opportunities for you to discuss concepts, compare notes, learn key study strategies, and gain a deeper understanding of the content, all while working as a group with others from your class.

If you have an SI Leader assigned to one of your courses, they will be introduced to the class in the first week. You can also find SI-supported courses and scheduled SI sessions for your course.

For Faculty

Dedicated faculty are essential for high-quality SI experiences! SI faculty commit to meet at least once a week with their Supplemental Instruction Leader and to maintain regular communication with the SI Supervisor. If you are an instructor and interested in receiving Supplemental Instruction (SI) support for your course, please contact our SI Supervisor, Kyle Castro (

Please keep in mind that support is limited due to funding and our focus is on historically difficult, face-to-face courses.
