Supplemental Instruction

Supplemental Instruction (SI) is an internationally recognized academic support program. SI is a voluntary program that offers free, regularly scheduled study sessions for traditionally difficult courses. SI sessions are led by current ISU undergraduate students who have successfully completed the course.

Proven to Work

Our data suggests that the more often students attend, the higher their final grades will be in the course. We recommend attending SI at least once per week.

Students who participate in SI:

  • Learn how to learn while learning what to learn.
  • Work collaboratively with peer students in a facilitated environment.
  • Receive support from a trained, educated SI Leader.

Our methods of collaborative study sessions have shown an average of over one-half letter grade improvement amongst students who regularly attend SI sessions.

We support more than 30 courses in these subject areas:

  • Accounting
  • Animal Science
  • Biology
  • Chemistry
  • Engineering
  • Math
  • Physics
  • Statistics, and more

Attending SI has tremendously improved my understanding of the course. The SI leader creates a positive learning environment where I am not afraid to ask for help or make mistakes.
