Supplemental Instruction (SI)

What is Supplemental Instruction?

Supplemental instruction (SI) is a peer-led, informal study group designed to help students succeed in academically demanding courses by:

  • teaching new ways to break down and understand difficult material
  • preparing students for lectures and exams
  • offering a friendly place to ask questions, make mistakes and share study tips
  • improving student confidence and performance
  • offering three regularly scheduled, weekly sessions for each SI supported course

Students who attend at least three SI sessions earn at least half a letter grade or better in the course.

Who can attend a session?

SI is free and open to all students enrolled in courses offering supplemental instruction.

Who leads the sessions?

SI sessions are led by a peer who holds a cumulative 3.5 or higher GPA and has either already successfully taken the course or mastered the material. SI leaders attend the course lectures for courses they lead, and they tailor their sessions to match the needs and pace.
