Business schools are increasingly concerned about retaining and recruiting new students. We examine interactions among marketing students to consider their consequences on student satisfaction. This article's objective is to determine the drivers of satisfactory and dissatisfactory student-to-student interactions by employing a critical incident technique. In doing so, this study identifies three groups (group assignments, peer relations, and outcomes) and 11 categories of satisfiers and dissatisfiers. The study's findings advance the understanding of the impact of students-to-student interactions on student satisfaction and illustrate the importance of the management of these interactions in the context of marketing education.
