What is SI?

Supplemental Instruction (SI) provides free, out-of-class study sessions led by a CWU undergraduate student who has already taken and excelled in the course. SI sessions are open to all CWU students enrolled in the SI-targeted class, and attendance at SI sessions is voluntary and confidential.

Used throughout the U.S. and the world, SI programs have proven highly successful in increasing student achievement and retention. Students who regularly attend SI sessions increase their chance of understanding the course material and improving their grade. In fact, on average, these students will earn a grade one-half grade higher than classmates who never attend SI.
