Supplemental Instruction (Peer-Led Learning Support)

Supplemental Instruction (Peer-Led Learning Support) 2025 - 2026 Academic Year

Supplemental Instruction (Peer-Led Learning Support) sessions offer students the opportunity to master course material within a community of learners. The SI (Peer-Led Learning Support) program gives students an environment to engage with content, ask questions, and review lecture material with their peers. SI (Peer-Led Learning Support) currently supports courses in Biology, Chemistry, Economics, Math, Physics, and Psychology. Learning with a group of peers is a powerful tool!

• SI (Peer-Led Learning Support) sessions are facilitated by peer leaders  (known as SI (Peer-Led Learning Support) Leaders) who have successfully completed the course at UC San Diego. These leaders are trained in facilitating sessions that encourage students to work together to learn course material. 
• SI (Peer-Led Learning Support) sessions meet weekly for 80 minutes
• SI (Peer-Led Learning Support) sessions are offered in a hybrid model, with in person and virtual sessions offered.

Program assessment over 5 years demonstrates that participation in Supplemental Instruction (Peer-Led Learning Support) supports students in obtaining a half letter grade higher than peers not participating in the program.

This year, we will be offering in-person and virtual session options for select courses. Please review the SI (Peer-Led Learning Support) Schedule for more information regarding your course.
