Much research has been done on the effectiveness of Supplemental Instruction programs, (Peer Assisted Study Sessions, PASS, in Australasia). Less research has emerged on on students' reasons for participating in PASS and their perceptions of the effectiveness of the program. In this article, we will report on a small improvement-focused research project at one university. Our particular focus will be to reflect on the survey tool we used and how we could improve the design and administration of this tool. Implications of the survey findings for improving the training program of PASS leaders in this institution will also be discussed.
