What Is Supplemental Instruction?

Supplemental Instruction (SI), created at the University of Missouri-Kansas City, is a non-remedial approach to learning that supports students toward academic success by integrating “what to learn” with “how to learn.” SI consists of regularly scheduled, voluntary, out-of-class group study sessions driven by students’ needs. Sessions are facilitated by trained peer leaders who utilize collaborative activities to ensure peer-to-peer interaction in small groups. SI is implemented in high-risk courses in consultation with academic staff and is supported and evaluated by a trained supervisor.


  1. To increase retention within targeted historically difficult courses
  2. To improve student grades in targeted historically difficult courses
  3. To increase the graduation rates of students

SI is a free service offered to all students in a targeted course. All students are encouraged to attend SI sessions, as it is a voluntary program. Students with varying levels of academic preparedness and diverse backgrounds participate.
